WHAT’S NEW IN CBC ACADEMICS By Dr. Dee Belle-Oudry

t’s an exciting time for our undergraduate programs as we are launching several new courses this year. In addition to the new foundational chemistry courses central to our revamped degree plans, we are rolling out some options that will appeal to students across disciplines. Introduction to Clinical Analysis (CHEM 365) focuses on chemical measurements in the clinical realm and their impact on health care. Various facets of clinical chemistry are explored including preparation of complex samples, types of instrumentation used, and how these measurements are used to diagnose and treat disease. Scientific Fundamentals of Forensic Science (CHEM 328) explores the forensic science realm with a particular emphasis on the scientific practices and procedures involving crime scene evidence evaluation.

CAREERS IN FORENSICS ELEANORE LEICHTENBERG

recently accepted a position with the Toxicology Unit of the Tucson Police Department Crime Laboratory. I earned my Chemistry BS degree at the University of Arizona in 2015, and I conducted research under Prof. Dennis Lichtenberger. While I was involved with the U of A Chemistry Club, we had a tour of the new TPD Crime Lab on Miracle Mile. I had been heavily interested in forensic science for some time but taking that tour solidified my interest in the field. After I earned my degree, and taking a few other jobs, I found employment in Albuquerque, New Mexico at the New Mexico Department of Health Scientific Laboratory Forensic Toxicology Bureau where I gained real-world experience in a nation-

ORGANIC CHEMISTRY FOR MAJORS By Dr. John Jewett

his story began many years ago while teaching the first semester of honors organic chemistry. A student came after class to ask a question. I informed them, “we’ll see this topic next semester,” to which they responded, “I love this class, but my major only requires one semester, and I can’t fit a second one.” From this interaction, the seeds were sown, awaiting germination to develop into a one-semester course in organic chemistry. A few years later, a key goal of my sabbatical was to envision a one-semester organic chemistry class from the ground up. This task involved identifying key topics and then working backward build the curriculum, using a blank notebook

to craft the course. The most important realization was that if I taught a carbonyl-centric view of organic chemistry, the students would be exposed to most core topics. Originally, I planned to write a textbook, but teaching during the pandemic taught me the power of videos. By observing my children consume media, I learned that short videos were the key. The next few times I taught organic chemistry I created topic-based, modular preclass videos, knowing that I could eventually

reorder them. My current CHEM 246 course has 37 required pre-class videos, and 16 “bonus” videos for organophiles. During the past two years, I served as a program director for the National Science Foundation (NSF) in “the nation’s chemistry department.” This role gave me a broader perspective of

I held many positions in this lab including working in the Breath Alcohol section where we maintained over 200 of the state’s Intoxilyzer 8000s and provided monthly trainings to certify law enforcement officers in the use of the instrument, acting as Quality Assurance Coordinator for the Toxicology Bureau to ensure and monitor compliance of the lab against accreditation standards, and as a Blood Alcohol/Drug Screening section supervisor. After almost 7 years in New Mexico, I moved back home to serve the community I grew up in. I spend most of my time outside of work camping and traveling.

Laboratory Technician, an entry level position, where I was mostly making reagents and performing instrument checks, but not analyzing evidence. In 2001, I was promoted to a Forensic Scientist, in the Seized Drug section, analyzing suspected controlled substances. In 2003, I was selected to the ATF’s National Firearms Examiners Academy in Maryland, where I trained to be a firearms examiner. As a firearms examiner, I would analyze firearms evidence to try and determine if a bullet or cartridge case was fired from a particular firearm. In addition to firearms analysis, I also performed toolmark analysis, where we attempt to identify if a tool had been used in a crime.

JOHN MACIULLA

In 2012, I was promoted to a Supervising Forensic Scientist, and supervised the Seized Drug, Firearms, and Latent Print sections at our laboratory. Throughout my career, I have supervised all the forensic disciplines at the laboratory, including DNA and Toxicology. In 2015, I was promoted to Laboratory Manager, where I am today. I oversee the operations of the entire Laboratory here in Tucson. I continue to maintain my proficiency in firearms analysis and manage to work on a case now and then.

I was lucky enough to find a career using my degree that has kept me in Tucson, allowing me to continue to attend U of A sporting events. I began my career in forensics at the Arizona DPS Southern Regional Crime Laboratory, in Tucson, in 1998. I started as a

cutting edge of chemistry and acted as a palate cleanser from my old teaching processes, providing the opportunity to teach new course, to a new generation of students, in a new way. I am indebted to colleagues, both in CBC and at the NSF, for questioning and challenging my thinking, plans, and goals. A special thanks to Dr. Hamish Christie, who created an amazing new majors’ lab to go along with the course. We chat frequently to synchronize learning outcomes. “Will they learn organic chemistry?” Yes and no. Students will learn the tools that allow them to navigate the beautiful landscape that is organic chemistry. They will not see all of it, nor would they in two semester sequences. The field is too large and constantly expanding. The goal is to provide students a foundation that will allow for growth, inquiry, and blooming into whatever kind of scientist they choose ... ideally chemists and biochemists.

NEW CLINICAL ANALYSIS COURSE BRIDGES CHEMISTRY AND HEALTHCARE

new undergraduate course in clinical analysis CHEM 365—Intro to Clinical Analysis will be introduced in Spring 2026. The course integrates analytical chemistry, biochemistry, and medical diagnostics to bridge the gap between foundational chemistry and modern healthcare practice, preparing students for careers at the intersection of science and medicine. Students will gain a working knowledge of instruments commonly used in clinical labs—spectrophotometers, chromatographs, and automated analyzers—while developing essential understanding of sample handling, data interpretation, and quality control. Through case studies, they learn to identify disease

markers, validate analytical results, and understand the correlations between chemical data and physiological conditions. This curriculum innovation addresses both student demand for applied, career-relevant education and a national need for qualified laboratory professionals. As healthcare evolves with advancing diagnostic technologies and precision medicine, professionals with strong grounding in clinical chemistry principles are increasingly vital to hospitals, research centers, and public health institutions. Students also develop expertise that is directly transferable to careers in clinical diagnostics, biotechnology, pharmaceutical research, and medical technology.

UNDERGRADUATE STUDENT SUCCESSES NATALIE RAWLINGS 2025 Astronaut Scholar and Goldwater Scholar

Natalie Rawlings is a senior pursuing a dual degree in Molecular and Cellular Biology and Biochemistry. Natalie fell in love with science and research at an early age when her parents bought her a simple 400x Smithsonian microscope. Her interest in science became more directed when her grandmother was diagnosed with an aggressive form of Amyotrophic Lateral Sclerosis (ALS) and died only months later. Losing her grandmother to a rare disease with so much left to be discovered about it filled her with a desire to understand and solve complex problems involving human health. Always wanting to understand the fundamental workings of the world, Natalie joined the lab of Dr. Andrew Capaldi during her first semester at the University of Arizona to study just that—the molecular basis of disease at a cellular level. In the Capaldi Lab, she studies a fundamental metabolic pathway that governs cell growth and proliferation, which may hold the key to understanding aging, cancer, and many other complex diseases. This summer, she took the knowledge she gained about cellular metabolism to St. Jude Children’s Research Hospital. There, she studied how anti-cancer molecules directly target a pediatric bone cancer known as Ewing sarcoma. Outside of research, Natalie loves being a leader and mentoring others. In her junior year, she founded the Undergraduate Journal Club, where she hosts weekly meetings to discuss interesting scientific publications with other undergraduates. She hopes the club will get more undergraduates excited about research and science. Natalie also has entrepreneurial interests and has led the renovation of a room in the College of Medicine Tucson, which she calls the “Room for Wellbeing.” This room is an innovative approach to student wellness that integrates VR technology, massage chairs, and biophilic design to enhance student wellbeing. Rawlings hopes to pursue an MD/PhD following graduation and hopes to continue investigating the molecular basis of disease to provide more treatment options for those suffering from rare, complex conditions. She specifically aims to contribute to mechanistic discoveries in the context of autoimmune diseases and rare cancers. Natalie is incredibly grateful for the support of many phenomenal mentors at the University of Arizona and for the immense support from the Goldwater Foundation and the Astronaut Scholarship Foundation to pursue a career in research.

CALEB KONECEK

Caleb Konecek, a senior in the Department of Chemistry and Biochemistry, is pursuing degrees in biochemistry, molecular & cellular biology, and Spanish with minors in classics and professional & technical writing. Throughout his undergraduate studies, Caleb has distinguished himself as a researcher and a scholar, evident by his receiving the Thermo Fisher Scientific Antibody Scholarship Award, the Excellence Award in Biochemistry, the Royal Society of Chemistry’s Certificate of Undergraduate Excellence, and Dr. Thomas M & Candace C Grogan Scholar. As a MARC program trainee conducting research in the Charest Lab, Caleb investigates the molecular pathways responsible for chemotaxis, a complex biological process with implications in cancer. He has attended numerous university and national research conferences, even receiving an award for his poster presentation at ABRCMS 2024. His passion for the environment emerged from his leadership roles in the Students for Sustainability club and the Epsilon Eta environmental fraternity, where he led teams of students in the development of sustainable service projects across Tucson. Following graduation, Caleb plans to pursue a Master of Science in biotechnology at the University of Galway in Ireland, after which he intends to intern with MicroGen Biotech, a company based in Ireland, to gain hands-on experience in the field of bioremediation. With this degree and training, Caleb plans to return to the United States to pursue a career with the Department of Energy where he will lead the development of novel techniques in environmental restoration.

SAM LAMOTTE, OUTSTANDING GRADUATE PEER MENTOR! By Sam LaMotte

I’m an analytical/physical chemistry major in the Monti Lab. After I get my doctorate, I’m planning on going into industry or maybe a government research facility where I can take advantage of the skills I’ve gained throughout my PhD. I think it is incredibly valuable to have people available to talk to who recently went through the same things. So, CBC putting together a program to help connect new graduate students with more experienced graduate students, such as myself, is great and I’m just happy to help and give advice where I can.

Co-founder of Dragonfly Mental Health

s a freshman, I joined Matthew Cordes’ lab in Biochemistry and Molecular Biophysics (BMB) and fell in love with research. In 2008, I graduated as the College of Science Outstanding Senior with a BS/MS in BMB and a BS in Psychology. While an undergrad, I met my best friend, Emily Dykstra, and my now husband, Christopher Bauer (m. 2018), both of whom were PhD students at the time. I went to UC Berkeley for my PhD in Molecular and Cell Biology, but in 2013, a spate of suicides in my department prompted a parallel path to my research on behavioral neuroimmunology—one of advocating for academic mental health. Following my postdoc in psychiatric epidemiology at Johns Hopkins in the Department of Mental Health, I began my current role as CEO of a global nonprofit in 2020. I co-founded Dragonfly Mental Health (dragonflymentalhealth.org), which has delivered 400+ educational programs to over 65,000 academics in 42 countries. We envision a world where academics take care of their minds like elite athletes take care of their bodies and this year the International Society for Bipolar Disorder recognized us for our global impact with the Mogens Schou Award for Public Service & Advocacy.

TOMI K. SAWYER

Founder & Chief Drug Hunter, Maestro Therapeutics; Founder & President, Peptide Drug Hunting Consortium

s a graduate student, I joined the Victor Hruby lab in the fall of 1976 (Department of Chemistry in those days). I did both biology and chemistry research (this included mentorship by Mac Hadley in the Department of Biology). My personal favorite part of the science was drug design. I was fortunate to have made two peptides (NDP-MSH and a macrocyclic analog Ac-cyclo[Cys4,10]a-MSH) which were the first superagonists of the melanocortin-1-receptor (MC1R). My career skyrocketed from my graduate studies and Victor Hruby will always be my scientific father and friend. My scientific odyssey has been an awesome one, and next year (2026) I will have been a drug hunter for 50 years! My wife (Constance) and I have two sons, Thomas and Jonathon, and they each have PhDs in science (in fact, Jonathon received his PhD with Victor Hruby in 2022). Both are now entrepreneurial drug hunters working with me at Maestro Therapeutics! Over the years, I have been a designer and synthetic chemist engaged in multiple drugs that have advanced into the clinic. Three are marketed medicines and more are on the way through biotech partners of Maestro Therapeutics. I’m credited with nearly 700 publications, patents and presentations highlighting breakthrough drug modalities (peptide, peptidomimetic, small molecule, and natural product) for receptors, proteases, protein-protein interactions, and other intriguing targets underlying complex diseases.

VICTOR J. HRUBY

A PRODIGIOUS LIFE OF ADVENTURE, ODYSSEY & LEGACY Dr. Hruby’s remarkable career, his enduring service to the University of Arizona and the Department of Chemistry and Biochemistry are highlighted in this story written by one of his earliest PhD students, Dr. Tomi K. Sawyer

FRIEND, COLLEAGUE, MENTOR & SCIENTIST For all of us, including his beloved family as well as enumerable friends and colleagues of Dr. Victor J. Hruby, this article is aimed to celebrate an extraordinary professor and scientist who hailed from Valley City, North Dakota, and through his passion of education as a teacher, mentor and researcher, rose to be one of the greatest peptide scientists for over fifty years. His achievements in peptide design, chemistry, biophysics, biochemistry, and pharmacology enabled translational research and drug development with a worldwide impact. How proud all of us are to have been a part of Victor’s journey and witness his great achievements.

A VIGNETTE OF BEING ONE OF VICTOR’S STUDENTS In 1976, I started my graduate studies in Chemistry at the University of Arizona with hope of doing neuropeptide research with Dr. Hruby. After finishing my coursework and preliminary written/oral exams, I was ready to start, and instead of doing chemistry, Victor asked me to work with Dr. Mac Hadley to establish some new biological assays to be used for testing a–melanocyte-stimulating hormone (a–MSH) analogs. Unfortunately, I struggled and despite very significant effort to finally succeed, it was Victor’s uncompromising faith and confidence in me that kept me going. This was Victor’s gift to all his graduate students and postdoctoral researchers. His enthusiasm, passion, and joy were for not only science, but for his team and collaborators. As a student, it was a good day to see Victor “on a roll” with something good happening in the lab or news from one of his collaborators. All of us who worked with Victor were witness to his perpetual youth and high energy, and this also melded into his iconic persona.

ADVENTURE, ODYSSEY & LEGACY OF A RENOWN MULTIDISCIPLINARY POLYMATH To know Dr. Hruby was to know his entire personal history (from childhood and what he learned in school to virtually every major event in his life, including family, education, science, humanity, symposia, publishing, and, of course, the University

of Arizona, and his many faculty friends and colleagues) as he loved to share his life with all of us. I’m not sure if there was a single adventure that dominated over others, because both sharing science and inspiring people were as important to Victor as his latest “peptide breakthrough”. Nevertheless, one adventure signifying the first of his major achievements was that of the discovery of [Nle4, D-Phe7] a–MSH (NDP–MSH), a peptide superagonist at the melancortin-1 receptor (MC1R). After years of further preclinical research at the University of Arizona, it (Afamelanotide) was ultimately developed and marketed (Scenesse®) by Clinuvel upon recent FDA-approval (2019) for therapeutic use in the treatment of specific pigmentary diseases. In a 1980 publication in the Proceedings of the National Academy of Sciences (USA), NDP-a–MSH brought a worldwide spotlight on both Victor and me as well as Mac Hadley as a breakthrough in peptide drug discovery. Soon after NDP–MSH, another superagonist, cyclo[Cys4,11] a–MSH, became the second breakthrough in peptide drug discovery for Victor, Mac and me. Again, years later, cyclo[Cys4,11]a–MSH provided the template for which Rhythm Pharma developed a modified fragment analog, Setmelanotide (Imcivree®), that was also recently FDA-approved (2020) and marketed for therapeutic use in the treatment of rare genetically related obesity diseases. Victor’s odyssey in the design and discovery of novel peptide analogs included opioid peptides (including the d–receptor agonist DPDPE, but also many agonist/antagonist peptides modulating the m– and k–opioid receptors) as well as oxytocin, vasopressin, cholecystokinin, substance P, glucagon, and glucagon-like peptide-1. His scientific reputation for the use of conformational constraints via macrocyclization and unique amino acids to design novel peptides with highly specific pharmacological properties was highly acknowledged worldwide. Victor’s legacy reflects more than fifty years (1970s-2020s) of a mind-boggling summation of >1000 scientific publications/ patents, hundreds of symposium lectures/seminars, and a long list of awards/honors (e.g., Guggenheim Fellowship, American Peptide Society Merrifield Award, Senior Humbolt Fellowship, ACS Arthur C. Cope Scholar Award, ACS Ralph F. Hirschmann Award, Jacob Javits Neuroscience Award, NIH MERIT Award,

He is acclaimed as one of the most celebrated members of the American Peptide Society, which he co-founded (1990) and was its first president. His legacy at the University of Ari-

zona includes his teaching, mentoring and scientific research, and he was honored many times to his last academic position as Regents Professor Emeritus. One time back in the early years, Victor mentioned to me that we (i.e., all who were mentored by him) were part of the legacy of his scientific family roots which included two Nobel Laureates and he was very proud to share this gift with us to inspire and see us aspire to do good work.

The scientific family legacy of Victor J. Hruby traces back to his postdoctoral mentor, Vincent DuVigneaud (awarded the Nobel Prize in Chemistry, 1955), a renowned mentor of DuVigneaud, Max Bergmann, and Bergmann’s mentor, Emil Fischer (awarded the Nobel Prize in Chemistry, 1902).

CONCLUDING REMARKS AND A SPECIAL TRIBUTE TO VICTOR J. HRUBY On behalf of all of us who have been part of Victor’s life, this is a story of the adventure, odyssey and legacy of Dr. Victor J. Hruby written from the perspective of a student who shared fifty years of knowing him as a mentor, a scientific father, a friend and one who admired the great person that he was. Through the years, Victor and I remained very close. He attended my wedding and we (my wife and two sons) took many vacations in Arizona that included visits with Victor and his wife Pat. And just a few years before Victor retired, another Sawyer showed up to be a part of the last chapter of this story. My youngest son, Jonathon, would also receive his PhD (2022) doing research with the Hruby team and co-authoring several of

DEPARTMENT OF CHEMISTRY AND BIOCHEMISTRY | FALL 2025

Victor’s last publications, including a focus on both MC4R-targeted macrocyclic agonists and novel ultra-short GLP-1 agonists for drug discovery focused on next-generation obesity therapeutics. Indeed, and so many other graduate students and postdoctoral scholars share this great legacy because of a gifted man, Victor J. Hruby, who chose to establish his career one day in 1968 at the University of Arizona. Yes, and how very lucky we all were because of this as we also share in giving a special tribute to a remarkable human being—Victor J. Hruby.

POWERING THE CELL

INVESTIGATING HOW ATYPICAL KINASES PROTECT MITOCHONDRIAL FUNCTION By Dr. Tarjani Thaker

very cell in the body relies on a tightly regulated network of proteins and enzymes that produce energy and maintain health. When sources of energy are disrupted for extended periods, stress-inducing molecules accumulate inside cells, resulting in significant consequences for health. The Thaker Lab investigates how a unique group of proteins, known as atypical kinases, maintains cellular stability by regulating processes at the intersection of energy metabolism and cell signaling, enabling cells to respond to and recover from stress. Our current research focuses on a specific subset of kinases from the ABC1 family, which reside within the mitochondria, the cell’s main energy-producing factory. Two members of this family, ADCK3 and ADCK4, play essential roles in producing Coenzyme Q10 (CoQ10), a lipid-like molecule that fuels cellular respiration and protects cells from stress. When these kinases are disrupted, CoQ10 levels drop, leading to energy loss, cell damage, and ultimately, organ dysfunction, as seen in kidney disorders, cardiovascular disease, and certain cancers. To understand how this occurs, our team combines biochemical reconstitution, high-resolution structural methods, and systems-level omics approaches to investigate how ABC1

roteins must fold into precise three-dimensional structures to function, yet the process is highly complex and error-prone. Misfolded or aggregated proteins can be toxic, particularly in neurons, leading to neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s Disease. Molecular chaperones are central to maintaining proteostasis by assisting in folding, preventing aggregation, and managing misfolded proteins under stress. Among them, Hsp60 and its co-chaperone Hsp10 play essential roles in ensuring correct protein folding and preventing aggregation, particularly within

kinase activity and its network of protein and lipid interactions maintain mitochondrial and metabolic health. We are particularly interested in how kinase crosstalk coordinates metabolism across different cellular compartments and how disease-associated mutations disrupt this regulation. By uncovering these mechanisms, we aim to identify new strategies for restoring cellular energy balance and developing treatments for diseases associated with mitochondrial dysfunction and CoQ10 deficiency.

mitochondria—organelles often compromised in neurodegenerative disorders. In contrast to the extensively characterized bacterial Hsp60 (GroEL), mammalian Hsp60 adopts multiple conformations (monomeric, heptameric, and tetradecameric) and displays distinct biochemical properties. Despite its importance, little is known about the molecular mechanisms by which Hsp60 maintains protein homeostasis and prevents protein aggregation. In the Wälti Lab, we investigate the molecular mechanisms underlying Hsp60/Hsp10 function. We combine a variety of biochemical assays with structural biology techniques, including NMR spectroscopy and cryo-electron microscopy (cryo-EM), to study and visualize different forms of the Hsp60/ Hsp10 complex. Cryo-EM reveals chaperone conformational dynamics, while NMR spectroscopy probes interactions with substrates and co-chaperones. Using human Hsp60 together with key substrates—such as malate dehydrogenase, superoxide dismutase, the Alzheimer’s peptide Aβ, and Huntington

ed light is more than a symbol of energy, it’s the driving force behind Dr. Thomas Gianetti’s pioneering research in organic photochemistry. The Gianetti Lab designs new carbocation-based photocatalysts that absorb low-energy red light to promote challenging chemical transformations under mild, metal-free conditions. These organic dyes open new possibilities for sustainable synthesis by replacing rare metal catalysts with tunable, earth-abundant molecular systems. Beyond catalysis, the same molecular platforms are being adapted for energy storage applications, where their redox stability properties enable innovative organic redox flow battery designs.

Building on this research foundation, Dr. Gianetti founded CarbeniumTec, a University of Arizona spinout company dedicated to advancing organic flow battery technologies. Its subsidiary, Flow6 Energy LLC, focuses on developing semi-solid symmetric battery systems that merge molecular catalysis principles with electrochemical stability, offering a pathway toward low-cost, safe, and recyclable long-duration energy storage solutions.

His work has already led to several high-impact publications, invention disclosures, and patents, underscoring the translational reach of Gianetti’s science. As the 2025 Donna B. Cosulich Faculty Fellow, he continues to bridge molecular design and practical innovation. “We aim to transform how molecules capture and store energy,” Gianetti says. “Whether it’s through light-driven chemistry or next-generation batteries, our goal is to make sustainable technologies both powerful and practical.”

STAFF RETIREMENT Dr. Andrei Sanov 2025 College of Science Distinguished Achievement in Science Education Award The COS Distinguished Achievement in Science Education accolade celebrates Professor Sanov’s decades-long commitment to innovative teaching and mentorship, marking a career dedicated to bridging mathematics, physics, and chemistry to inspire students at every level. Dr. Sanov joined Arizona in 1999 and built an internationally recognized research program in photoelectron imaging spectroscopy—work that deeply informs his approach to teaching. Sanov’s philosophy rejects silos: “No area of science exists in a vacuum,” he asserts, framing chemistry education as “an application of mathematics to the molecular universe.” In collaboration with colleagues, he has pioneered several groundbreaking courses over the span of his career. Partnering with Professor Oliver Monti, he launched the graduate course in Mathematical Methods for Chemists (CHEM 581) and its undergraduate counterpart, Mathematical Physics for Chemistry (CHEM 380). Together with Regents Professor Steven Schwartz, he co-created a new quantitative general chemistry lecture series (CHEM 141-142). The original classroom modality of this course was adapted for online delivery just before COVID-19, aiding thousands of students during remote learning. The new general chemistry curriculum eventually evolved into Majors General Chemistry (CHEM181-182), where UA students majoring in Chemistry, Biochemistry, and Engineering consistently outperform national averages on standardized ACS exams. Most recently, Sanov redesigned the undergraduate course in Quantum Mechanics and Spectroscopy (CHEM 480A: Physical Chemistry II), using a “Chemistry: The Coupling Science” approach born from joint research with Professor Laura Van Dorn. Students vividly praise his impact: “Dr. Sanov is one of the best professors I’ve had here at the U of A,” shares one. “Everything seems so easy when he explains it... this was the best class at the UA that I’ve ever been in,” adds another. Sanov is now involved in the design of the Quantum Universe track in the revamped Chemistry BS curriculum, continuing to ignite scientific curiosity in the next generation.

Cindy Neal

Assistant Director, MARC Program In 1999, I was given an incredible opportunity to be part of a nation-wide program dedicated to training and preparing undergraduate STEM students to go to graduate school in pursuit of a PhD in some area of biomedical research. The University of Arizona Maximizing Access to Research Careers (MARC) program has successfully impacted hundreds of students to matriculate into many amazing PhD programs across the United States. I am so grateful to Dr. Marc Tischler for taking a chance on me, guiding me and teaching me how to best make a difference in students’ lives. I have learned so much from the students who have crossed my path. They have inspired me, motivated me to be a better version of myself and to try harder to help even more students navigate their paths. I have loved the many relationships that were created by this opportunity on campus with the staff, students and faculty involved in UROC, ASEMS, UBRP, USIP and many more. It’s funny that for many years I felt I would never reach retirement. It always seemed so far away – until it wasn’t! All of a sudden, I had hit a milestone that said I was eligible to retire. Where did the time go??? Although the actual milestone date had come and gone, I felt I still wasn’t ready to let go and wanted to keep going for a few more years. Then … earlier this year, the program I’d been part of for almost 26 years found itself terminated. At that point, it felt like the decision was made for me and would be a “natural” break. I truly appreciate Dr. Katrina Miranda for her continued support especially when the road got rough for the MARC Program. With the decision made, I could then focus on what the next chapter would look like. My husband and I moved to Texas to be closer to our grown children and grandchildren. We’re now able to attend all the fun things the grandkids have invited us to – grandparents’ day at school, baseball games, softball games and dance recitals. Another major part of retiring was the plan to travel. There are many places on my bucket list and now I just need to move through those. I’m so grateful for the career that I had and the many people who were integral parts of it. My goal was always to make some small difference in the lives of people who wanted my help and to leave things better than when I got there. I surely hope I did.

FACULTY RETIREMENTS Professor Dennis Lichtenberger My career at the University of Arizona I was incredibly fortunate to have been hired by the UA Chemistry department (purely by happenstance John Enemark had attended my PhD defense at the University of Wisconsin two years prior). I have enjoyed teaching at Arizona for 49 years, missing only a single class (due to COVID). Especially rewarding was initiating a research-focused course in computational chemistry in my first year and keeping it state-of-theart through the years. I’ve been fortunate in many research explorations and discoveries. Examples include: • Developing an instrument with unprecedented precision for measuring electron energies of neutral molecules. This instrument opened the door to numerous discoveries and rewarding collaborations in cutting-edge areas of inorganic, organometallic, and materials chemistry. • Predicting and later proving a highly stable molecule with a quadruple bond and the lowest ionization energy – strongest reducing power—of any neutral molecule (reported by Science and selected for ACS Chemistry Highlights). • Discovering an iron-sulfur-based electrocatalyst that rivals the efficiency of platinum in producing clean and sustainable hydrogen fuel from neutral water. Midway through my career at Arizona, I accepted the position of Department Head. I was fortunate that this period saw rapid growth in the department’s undergraduate enrollment and graduate program that enabled the hiring of many excellent faculty and expanding the staff and facilities. Along with this growth, one of my principal accomplishments was securing construction of the Chemical Sciences building. My greatest fortune has been sharing the excitement of science and discovery with many wonderful students – over 150 undergraduate students, 50 graduate students, and 27 postdoctoral researchers. I’ve also benefitted immensely from my colleagues, the friendly and dedicated staff, and other outstanding professors in research collaborations (over 75 faculty collaborators in total). As a “retired” Emeritus Professor, I look forward to continuing my professional work and collaborations, and exploring new scientific areas.

Professor William Montfort Looking back after years of looking forward is a challenge (lab motto: “How’s it goin’? Any data?”). But looking back brings a smile, especially for the more than 100 delightful scientists who somehow agreed to join my laboratory. They arrived from across the United States and around the world – Europe, Asia, South America, Canada and Mexico. Become a scientist, meet the world. I joined the University of Arizona for its breadth and the chance to understand how life emerges from simple molecules. While I still don’t know the answer, I’ve gained ground on the question with the help of scientists spanning Mathematics to Cancer Biology. Together, we published over 100 manuscripts. What could be more fun? Other fond memories include those of our truly enjoyable faculty and staff. The students of the Biological Chemistry Program, which I led for over 20 years. The remarkable students I taught in the classroom. The chance to Co-Led Clinical and Translational Oncology in the cancer center. I gained far more than I gave. What an experience. What’s next? I still have science to pursue, many things to learn, and new places to explore with friends, family, and my partner for life, Martha.

Regents Professor Jeanne Pemberton Hired right out of graduate school as an Assistant Professor in 1981, I have spent my entire career at the University of Arizona. Boy, was I young! I was the first woman hired to the tenure track faculty in the Department of Chemistry and was the only woman faculty member in the Department until we hired Professor Ann Walker in 1990. I arrived at Arizona with the belief that an academician should strive to excel in all facets of the job including research, education and service, and I structured my career to try to attain that ideal to the best of my abilities. Any success I have had in research has been the result of the hard work, dedication, and brilliance of my students; they were the “closed-toe shoes in the lab” who wrestled my crazy research ideas to the mat and turned them into tangible reality - for their risk taking and vision, I am forever grateful! I could not have asked for

IN MEMORIAM Dr. Hans Bohnert 1944–2025

Our friend and colleague Hans Bohnert passed away in May of this past year. Hans joined the University of Arizona Department of Biochemistry as Associate Professor in 1983. He established a robust program in desert plant biology, biochemistry, and stress survival. He was promoted to Full Professor in 1989.

Dr. Dennis H. Evans 1939–2024

Our former faculty colleague, Dr. Dennis H. Evans, passed away on March 26, 2024. Dennis was a Professor of Chemistry at Arizona from 2004-2009. He was born in Grinnell, Iowa on March 28, 1939 and began his schooling in a one-room schoolhouse. Dennis attended Ottawa College in Kansas, where he was Homecoming King, an All-American football player, and an ordained Baptist minister. After earning his chemistry degree, he pursued a PhD at Harvard under James Lingane, sparking his lifelong passion for electrochemistry. Internationally renowned for meticulous experimentation and insightful analysis, Dennis was truly an electrochemist’s electrochemist. Beyond his brilliance, he was humble, generous, and deeply loved by students and colleagues for his calm, helpful nature. Dennis is survived by his wife of 37 years, more out of a career. I wish I could say that this was my grand plan from the beginning, but I am amazed in hindsight by my good fortune! Yes, it was a lot of hard work, but yes, it was also immensely fun and constantly stimulating and rewarding. Overall, it has been one heck of a wild ride!! Retirement? Really?? Not really a word that has ever been front-and-center in my vocabulary! For the foreseeable future, my “retirement” is in name only, as I will spend the next few years finishing out my last graduate and undergraduate student researchers and wrapping up our current exciting research. As time permits, I plan to play more golf and hike, travel to see the places still on my bucket list, and to spend more time with friends and family. But, I will never lose my passion for the basic scientific discovery process (so much science to do, so little time ….), and when I finally do shutter my own lab, I hope to continue my engagement in research in the labs of my junior colleagues.

IN MEMORIAM Hans Bohnert 1944–2025

Our friend and colleague Hans Bohnert passed away in May of this past year. Hans was born and educated in Heidelberg, achieving his PhD at the University of Heidelberg in 1972, where he focused on mitochondrial DNA in plant development. Following postdoctoral studies, Habilitation and studies as an EMBL Fellow, Hans joined the University of Arizona Department of Biochemistry as Associate Professor, in 1983. He established a robust program in desert plant biology, biochemistry, and stress survival. He was promoted to Full Professor in 1989. Hans developed a large, joyful, collaborative, unruly, and outgoing group of plant biologists and biochemists on the fifth floor of Biological Sciences West. He was an excellent colleague and generous with his time, readily available with insightful suggestions and advice, often with a unique twist outside of mainstream thinking. He published extensively with Richard Jensen while in Tucson, who added analytical rigor to many of Han’s outlandish ideas. Their 1992 PNAS and 1993 Science publications are good examples, describing a transgenic tobacco plant engineered to produce mannitol, leading to protection against salt stress. Other studies involved critical plant complexes RuBisCO and PEP carboxylase, and protein import into chloroplasts. Hans left Tucson in 2001 to direct the Center for Comparative and Functional Genomics at the University of Illinois in Champagne-Urbana (UIUC), where he continued to collaborate, publish, and develop young scientists. Hans was a prolific publisher with over 350 publications and 40,000 citations, and was elected a Pioneer Member of the American Society for Plant Biology (read more). Hans retired in 2011 and returned to Tucson and desert life. He is survived by his wife, Regina, their two sons, and four grandchildren, as well as his brother, Dieter. He was a joy to know and is greatly missed.

schooling in a one-room schoolhouse in rural Iowa. Dennis attended Ottawa College (now Ottawa University) in Ottawa, Kansas, where he was, quite remarkably, Homecoming King, an All-American football player, and where he became an ordained Baptist minister. After receiving his degree in chemistry, Dennis continued his education at Harvard University, receiving his PhD in 1964 for his Dissertation entitled “Studies in Chronopotentiometry” under the direction of James Lingane, one of the most prominent analytical chemists of the time. This was the start of Dennis’ lifelong love and passion for the study of electrochemistry. Dennis was an electrochemist’s electrochemist! He was internationally renowned for his electrochemical prowess based on decades of careful experimentation and deep and insightful analysis of complex electrochemical processes. Much of his work focused on the redox chemistry of organic and organometallic systems, especially those involving nuanced electron transfer-linked structural and configurational rearrangements, and electron and coupled proton-electron transfer mechanisms by these complex redox-active molecules. His work resulted in almost 240 scientific publications with more than 11,400 citations. For his seminal contributions to electrochemistry, Dennis was awarded the American Chemical Society Award in Electrochemistry, the Manuel Bazier Award in Organic Electrochemistry from The Electrochemical Society, and the Riley Award in Electrochemistry from the Society of Electroanalytical Chemistry, and he was elected a Fellow of The Electrochemical Society. As an additional indicator of the high esteem in which his science was held, Dennis served as an Associate Editor for the Physical and Analytical Electrochemistry section of the flagship journal of The Electrochemical Society, Journal of the Electrochemical Society. Dennis started his independent academic career in the Department of Chemistry at the University of Wisconsin-Madison where he rose through the ranks to eventually become the Meloche-Bascom Professor of Chemistry before moving to the University of Delaware in 1986 with his also-chemist wife, Professor Mary Wirth. In what can only be described as an outstanding dual hire, we were able to hire both Dennis and Mary as analytical chemistry faculty members here at Arizona in 2004. During his relatively brief stint here, Dennis’ career continued to flourish with the establishment of several strong and highly productive collaborations with Professors Richard Glass and Dennis Lichtenberger. Of Dennis’ contributions to these efforts, Professor Lichtenberger recounts: “I was aware of the respect Dennis Evans was receiving in his early years at the University of Wisconsin when I was a graduate student there, but I didn’t fully appreciate what a

wonderful person he was until the fortunate crossing of our paths again at Arizona. In the early stages of our collaboration with Professor Glass, Dennis was invaluable in the discovery of a highly efficient electrocatalyst for hydrogen production. Dennis would carefully and patiently explain the subtleties of electrochemistry to me (a gas-phase spectroscopist and computational chemist up to that point) and our group. I remember he was always congenial in sharing his time and expertise with anyone and always with a friendly smile that I still see. I am tremendously thankful for Dennis springboarding my continuing work in electrocatalysis. I am also very thankful for knowing Dennis as a model for professional and personal interactions and as a model for how to live in general.” Dennis was a genuinely kind and thoughtful, humble and generous person, and he was loved by his students and colleagues alike. Always willing to offer a helping hand, his calm and steady demeanor left a lasting impression on those who had the pleasure of working with him. Dennis is survived by his wife of 37 years, Mary Wirth, a brother, two sons John and Andrew and their families, and a rich extended family. He will be missed - it was indeed our true honor and good fortune to have him as a colleague at Arizona!

Professor Richard S. Glass 1943–2025

The Department of Chemistry and Biochemistry is saddened by the passing of Professor Richard S. Glass, an extraordinary scholar, mentor, and friend whose impact on science and education spanned more than six decades. Born in New York City in 1943, Richard Glass graduated from the Bronx High School of Science, earned his B.A. in Chemistry from New York University in 1963, and completed his Ph.D. in Organic Chemistry at Harvard University in 1967 under Nobel Laureate E.J. Corey. After a brief tenure at Hoffmann– La Roche and Stanford University, he joined the University of Arizona in 1970, where he served with distinction for 55 years, since 2018 as Professor Emeritus. He was elected a Fellow of the American Association for the Advancement of Science in 1984 and authored more than 350 publications and 16 U.S. patents. Professor Glass was a pioneer in organosulfur chemistry. In addition to his independent scientific advances, he shared his expertise and elevated the works of many local, national, and international collaborators. Through these efforts he maintained countless relationships as a dedicated mentor and steadfast friend. Groundbreaking contributions were made in several areas, including but not limited to: • Sulfur-based polymers and inverse vulcanization – transforming elemental sulfur, a petroleum byproduct, into advanced materials for energy storage, infrared optics, and sustainable plastics.

DEPARTMENT OF CHEMISTRY AND BIOCHEMISTRY | FALL 2025

• Bioinspired catalysis—developing iron–sulfur hydrogenase mimics to advance the hydrogen economy and renewable energy technologies. • Electrochemistry and molecular design – elucidating fundamental principles of redox chemistry and stereochemistry. His work bridged organic synthesis, materials science, and energy science, influencing both fundamental science and applied technologies. Richard Glass was as dedicated to his students as he was to his research. He mentored dozens of graduate students and postdoctoral fellows, many of whom have gone on to distinguished careers. His graduate-level courses in physical organic chemistry were highly regarded, and he received the Faculty of Science Career Teaching Award in 1990. Students and colleagues remember him for his clarity, rigor, and generosity of spirit. Beyond his profession, Richard was known for his kindness, humility, and sense of humor and clever remarks. He loved traveling and immersing himself in other cultures and languages, fine food and wine, and collecting stamps and coins. Above all, he cherished time with his family. His passing came just days after the death of his beloved wife, Susan, his partner of 54 years—a testament to their deep bond. Professor Glass’s legacy lives on in the scientific literature, in the careers of those he mentored, and in the hearts of his family, friends, and colleagues. His contributions to science and humanity will continue to inspire generations to come. The Richard and Susan Glass Memorial Scholarship Endowment has been established by his family through the University of Arizona Foundation to support graduate students pursing a PhD in the Department of Chemistry and Biochemistry. Contributions can be made online. Additionally, you may share memories of Professor Glass or his impact.

NEW STAFF

Riley McCarty, contd. of Arts in Psychology with a minor in Business Administration. Working in Special Education taught me the value of patience, empathy, and adaptability. I learned how to communicate effectively across a wide range of abilities, advocate for individual needs, and collaborate closely with families and multidisciplinary teams to support student success. In IT Support, I learned strong technical and problem-solving skills that allowed me to best tailor support for each student. Outside of work, my full-time job is entertaining my cat, Funyun. Also, I tend to spend my free time listening to music, hiking, traveling, and playing video games. I’m really looking forward to supporting the CBC and helping things run smoothly behind the scenes.

RETIREES Professor Dennis Lichtenberger My career at the University of Arizona has been marked by good fortune in many respects. First, I was incredibly fortunate to have been hired by the UA Chemistry department (purely by happenstance John Enemark had attended my PhD defense at the University of Wisconsin two years prior). Since joining the University of Arizona, I have had the great satisfaction and fun of teaching for 49 years, missing only a single class (due to COVID). One of my most rewarding accomplishments has been initiating and continually modernizing the research-focused, state-of-the-art course in computational chemistry and molecular modeling—an area that has advanced tremendously since the course’s inception in 1977. Throughout my research career, I’ve been especially privileged to experience the joy of exploration and the thrill of discovery. Examples include: • Developing an instrument with unprecedented precision for measuring electron energies of neutral molecules. This advancement opened the door to numerous discoveries and rewarding collaborations in cutting-edge areas of inorganic, organometallic, and materials chemistry. • Measuring the photoelectron spectrum of C60 (buckminsterfullerene) shortly after its discovery. At the time, our published paper was the fourth most cited across all scientific disciplines. • Predicting and later proving a highly stable molecule with a quadruple bond and the lowest ionization energy – strongest reducing power – of any neutral molecule. This achievement was published by Science and selected for ACS Chemistry Highlights. • Discovering and continuing to develop an iron-sulfurbased electrocatalyst that rivals the efficiency of platinum in producing clean and sustainable hydrogen fuel from neutral water. Midway through my career at Arizona, I accepted the position of Department Head. I was fortunate that this period saw rapid growth in the department’s undergraduate enrollment, faculty, graduate program, staff, and facilities. Along with this growth, one of my principal goals was to secure funding and initiate the construction of the Chemical Sciences building. While I planned to achieve this goal in four years and return full-time

to my love of teaching and research, it ultimately required eight years due to frequent turnover in the University administration. My greatest fortune has been the opportunity to share the excitement of science and discovery with many wonderful and highly talented students – over 150 undergraduate students, 50 graduate students, and 27 postdoctoral researchers. I’m grateful that I had grant funds to support these students throughout their time with me. I’ve also benefitted immensely from my colleagues, the friendly and dedicated staff, and other outstanding professors in research collaborations (over 75 in total). I attribute all of my successes and recognitions to these people. As a “retired” Emeritus Professor, I plan to finish a substantial backlog of nearly completed manuscripts and continue my research and collaborations. I look forward to exploring new scientific areas and contributing to their development.

Dr. William Montfort Looking back after years of looking forward is a challenge (lab motto: “How’s it goin’? Any data?”). But looking back brings a smile, especially for the more than 100 delightful scientists who somehow agreed to join my laboratory. They arrived from across the United States and around the world—Europe, Asia, South America, Canada and Mexico. Become a scientist, meet the world. I joined the University of Arizona for its breadth and the chance to understand how life emerges from simple molecules. While I still don’t know the answer, I’ve gained ground on the question with the help of scientists spanning Mathematics to Cancer Biology. Together, we published over 100 manuscripts. What could be more fun? Other fond memories include those of our truly enjoyable faculty and staff. The students of the Biological Chemistry Program, which I led for over 20 years. The remarkable students I taught in the classroom. The chance to co-lead Clinical and Translational Oncology in the cancer center. I gained far more than I gave. What an experience. What’s next? I still have science to pursue, many things to learn, and new places to explore with friends, family, and my partner for life, Martha.

Jeanne E. Pemberton Career in Brief Hired right out of graduate school as an Assistant Professor in 1981, I have spent my entire 44-year career at the University of Arizona. Boy, was I young! In fact, when I started, I was younger than quite a few of the graduate students in chemistry at the time, which was, at times, a very weird dynamic. And speaking of Diversity, Equity and Inclusion, I was the first woman hired to the tenure track faculty in the Department of Chemistry. In fact, I was the only woman faculty member in the Department until we hired Professor Ann Walker in 1990; that intervening period was not without its challenges but was made immeasurably more bearable by the continued support and encouragement of faculty colleagues Mike Burke, John Enemark, and Dennis Lichtenberger, who always had my back. As it turned out, I was the first woman to rise all the way through the tenure track ranks to Full Professor (1992), eventually becoming a Regents Professor (2005). I was honored to hold the John and Helen Schaefer Professorship in Chemistry from 2001-2023 and the Homer and Emily Weed Endowed Chair in Chemistry & Biochemistry from 2023-2025. I arrived at Arizona with the belief that an academician should strive to excel in all facets of the job including research, education and service, and I structured my career to try to attain that ideal to the very best of my abilities. My research program in chemical measurement science, broadly defined, flourished here at Arizona in large part due to the excellent state-of-theart instrumentation facilities that the Department developed and sustained, along with their outstanding professional staff. Through a collaboration with Professor Raina Maier in the Department of Environmental Science, we also developed an interest in sugar-based materials, the range of which we have expanded greatly for various functional purposes. Our efforts have led to multiple patents and the co-founding with Professor Maier of a small company, GlycoSurf, which is now located in Salt Lake City and led by a former undergraduate researcher in my group, Dr. Chett Boxley. Any success I have had in research has been the result of the hard work, dedication, and brilliance of my students; they were the “closed-toe shoes in the lab” who were willing to wrestle with some of my crazy research ideas and turn them into tangible reality - for this risk taking and vision on their parts, I am forever grateful! I have mentored 45 Ph.D. students and numerous master’s students, postdoctoral researchers, visiting scientists, and undergraduate students in research. Our research was continuously federally funded for 42 straight years, largely by the National Science Foundation and the Department of Energy. Here at Arizona, our research was enriched by collaboration with faculty colleagues Steve Schwartz, Raina Maier, Robin Polt, Neal Armstrong, Vicki

Wysocki, and Erin Ratcliff. Quite satisfyingly, our work has been recognized with multiple national awards and other kudos. In addition, I am honored to have been elected as a Fellow of the American Association for the Advancement of Science, a Fellow of the American Chemical Society, and a Senior Member of the National Academy of Inventors. I have tried to give back to the profession through extensive professional service. Notable among these contributions, I have served as an Executive Editor of the ACS journal Analytical Chemistry since 2019 having previously served as Associate Editor from 2008-2019. Additionally, I was co-Editor of Annual Review of Analytical Chemistry. I do hope that these activities, along with my service on scientific advisory boards and committees, editorial advisory boards, and review boards and committees too numerous to cite for the National Science Foundation, Department of Energy, National Research Council, American Chemical Society, College Board, IUPAC, the European Research Council, and various scientific journals and academic departments, have left the profession better off, even if only by a little. Through these activities, I have accumulated over four million air miles, and I have been fortunate to visit and interact with other professionals in many corners of the world (usually at someone else’s expense!), which has been personally quite broadening. I could not have asked for much more out of a career, and I wish I could say that this was my grand plan from the beginning …. Ha - it wasn’t, and for that reason, I am truly amazed in hindsight by my very good fortune! Yes, it was a lot of hard work, but yes, it was also immensely fun and constantly stimulating and rewarding. Overall, it has been one heck of a wild ride!! Retirement? Really?? Not really a word that has ever been front-and-center in my vocabulary! For the foreseeable future, my “retirement” is in name only, as I will spend the next few years finishing out my last graduate and undergraduate student researchers and wrapping up our current exciting research. As time permits, I plan to play more golf and hike, travel to see the places still on my bucket list, and to spend more time with friends and family. But, I will never lose my passion for the basic scientific discovery process (so much science to do, so little time ….), and when I finally do shutter my own lab, I hope to continue my engagement in research in the labs of my junior colleagues.

Chemistry PhD, 1987 (Research Mentor: Neal Armstrong) Dr. David J. Mangelsdorf received his BS in Biology and Chemistry from Northern Arizona University in Flagstaff (1981) and his PhD in Biochemistry from the University of Arizona in Tucson (1987). He did his postdoctoral studies at The Salk Institute for Biological Studies. Since 1993, he has been at UT Southwestern, where he currently is Professor and Chair of the Department of Pharmacology and an Investigator of the Howard Hughes Medical Institute. He holds the Raymond and Ellen Willie Distinguished Chair in Molecular Neuropharmacology, in Honor of Harold B. Crasilneck, PhD and the Alfred G. Gilman Distinguished Chair in Pharmacology, and he is a member of the National Academy of Sciences. Dr. Mangelsdorf runs a joint laboratory with Dr. Steven Kliewer, and together their research team is focused on nuclear receptor regulation of metabolism. Their early work identifying the ligands and physiologic functions of a number of orphan nuclear receptors led them to discover two new signaling pathways mediated by the endocrine factors FGF19 and FGF21, which govern nutrient metabolism during feeding and fasting. Together, this work has uncovered potential therapeutic targets for diseases such as cholestasis, type 2 diabetes, and obesity. The Mangelsdorf/Kliewer lab also discovered the existence of a nuclear receptor pathway in parasitic nematodes, and has shown that pharmacophores that target this pathway may represent a new class of anthelmintic agents.

In 2011, I moved to Hungary to pursue a Doctor of Medicine degree at the University of Szeged, graduating summa cum laude in 2017. With my MD in hand, I moved yet again, to Inverness, Scotland where I started working in the British medical system, initially rotating through a wide range of specialties, finally settling in Emergency Medicine, where I have found my true passion in medicine. There’s never a dull moment, and I never get bored at work! I was given the opportunity to move to the Isle of Man (a small island in the Irish Sea best known for our death-defying motorcycle races, the TT Road Races!). I’ve been here on the Isle of Man for the last three years, currently working as a Specialty Doctor in Emergency Medicine. It’s a relatively small district general hospital, but for the two weeks during the TT Races, our Island comes alive, and we get to deal with the real bread and butter of Emergency Medicine. We see a lot of trauma as the racers barrel down our country roads at 200+ mph, sometimes not staying on two wheels! In addition to working in the Emergency Department during the races, I do a lot of pre-hospital work at the trackside, providing initial care and stabilization (and intubation!) to injured racers if they come off somewhere along the 37-mile course! I continue my journey to visit every country on the planet. My current country count is 124 countries visited. I prefer the off-the-beaten-track destinations, with my personal favorites of Pakistan, Iran, Iraq and Namibia. Generally, the worse the reputation of the country on the international scene, the more I’ll like it! Covid put a temporary halt on my travelling journey, starting with getting stranded in Monrovia, Liberia when the world shut down in 2020, but I’m so happy the world is open again and I can continue to explore. In 2022, I fulfilled another one of my dreams and earned my Private Pilots License. I was so fortunate to be able to learn to fly in the beauty of the Scottish Highlands and continue to get up in the skies as often as I can.

I had always wanted to transition to a career in the life science industry, however, so I persistently pursued job leads for several years. Finally in 2016 I was hired as a Research Scientist at MilliporeSigma in Temecula, California. My current research focuses on characterizing patient-derived organoids (mini-tissues or tumors that can be grown in the lab) for a wide range of research applications including drug testing and personalized medicine. October 2025 marks 9 years with the company. I am truly thankful to have my dream job and be able to contribute to a very exciting field! Outside of work, I continued playing violin with a Baroque music ensemble at UCSD and at church, where I was ordained as a deacon in 2018. I met my wife Wenyan in 2015, we married in 2017, in La Jolla. At our wedding it was wonderful to have so many special people from all our lives come together, including many friends from Tucson. We settled in north San Diego County, where we planted fruit trees and started raising chickens. We were able to take some memorable trips, first a national park road trip with my friends I met in Tucson, then to China in 2018 to travel with Wenyan’s extended family, and to the UK (my mother’s birthplace) in 2019. After 7 years just by ourselves, we almost gave up hope for having a child, but our miracle baby Josiah was born in April 2024. We are expecting our second child in March 2026!

Marisela Rodriguez

Biochemistry BA, 2018 (Research Mentor: Jason X-J Yuan), Clinical Translational Science MS 2020, Clinical Translational Science PhD 2025 Hi, I’m Marisela Rodriguez. My story with the University of Arizona continued after a Bachelor of Arts in Biochemistry in 2018 up until 2025. Encouraged to participate in research by our Chemistry & Biochemistry Department, I found the laboratory of Dr. Jason X-J Yuan as an undergraduate where I spent countless hours immersed in pulmonary hypertension research. I grew up in a small western town northwest of Phoenix and had never been exposed to research. I moved to Tucson for the first time away from my family, thinking I would one day be going to medical school. Although as time progressed biomedical research had sparked a deep interest in me. Upon conclusion of my undergraduate studies, I pursued a Master of Science in Clinical Translational Sciences with a commitment to translational impact. I remained in the laboratory of Dr. Yuan and realized that continuity gave me a depth of insight and perspective into critical thinking that began to mold a passion and purpose for research. I loved everything about it- the discussions, framing hypotheses, troubleshooting and storytelling for all I could find. A pivotal moment came when I was awarded a minority graduate student supplement grant, and I moved with the lab to the University of California San Diego whilst remaining a student of U of A. For me it was a leap—geographically, professionally, and personally. In San Diego, I navigated the challenges of the 2020 pandemic while simultaneously working in the biotech industry, applying my skills in real-world therapeutic-translational settings, working with a company that holds focus on protein degradation in cancer and inflammatory diseases. Despite the chaos, I graduated with my Master’s degree in October of 2020. Recognition followed: I was honored as Best WAESO Scholar and celebrated at the 70th National Science Foundation Celebration. But I wasn’t done. I returned to Tucson to pursue a PhD in Clinical Translational Sciences, bringing with me not just experience, but a renewed sense of purpose- I no longer held the idea of medical school. In 2022, I was married and officially admitted into the PhD program. That year, I was awarded an Environmental Toxicology of Human Disease T32 Award from the department of Pharmacology and Toxicology directed by Dr. Nathan Cherrington, which supported my research and affirmed in me the value of the work I was contributing to- I was motivated by it. Suddenly, I packed up again—this time heading to the Herbert Wertheim UF Scripps Institute in Jupiter, Florida. There I continued my PhD research in the laboratory of Dr. Joe G.N. Garcia and watched my mentor form and be the founding director of the Center for Inflammation Science and Systems Medicine. Fueled more than ever, I was solving a mechanism of secretion for an enzyme involved in NAD+ synthesis intracellularly and then categorized as an inflammatory biomarker extracellularly. I was awarded the prestigious F31 grant from the National Institute on Aging and the NIH, a milestone that underscored the translational relevance of my work and has become life changing. In March 2025, I defended my PhD project with a passion for nutrition, awareness of inflammatory triggers, and the exploration of biological components within the longevity space. This August, I officially earned my doctorate. A moment of triumph, reflection, and deep gratitude. Today, I’ve moved back across the country once more, closer to family and the beach, in San Diego, California. This journey has been anything but ordinary and I

Leah Vanprooyen

Biochemistry BA, Molecular and Cellular Biology BS 2019 I graduated in 2019 with a BA in biochemistry and a BS in molecular and cellular biology, and. Initially after college I went to work for a blood sample testing laboratory called Creative Testing Solutions. I worked in the SDS department, (supplemental donor screening), testing for antigens and antibodies in donor blood samples. However, I left that job for a better career at CND Life Sciences, where I preformed immunoflourescent staining of skin biopsy samples to check for phosphorylated alpha synuclein. CND Life Sciences was an amazing lab to work for, as the testing we preformed helped doctors distinguish between Parkinson’s disease, Lewy body dementia, REM sleep disorders, and certain autonosomic immune disorders. It is the first and only test available using a minimally invasive biopsy to check for these diseases. In addition to working for CND Life Sciences, some other major events in my life include marrying my college boyfriend Tyler Lebhart, and us having our first child together, (our son Oliver), in September of 2022. As well as in 2024 we made a big decision to move to Georgia for my husband’s career, and I put my career on hold to become a stay-at-home mom to our son. Now that we have learned we are expecting our second child, I most likely won’t return to the work force for a bit. But I am happy being a mother to our little boy and can’t imagine our life without him.

Biochemistry BS, 2025 (Research Mentor: Michael Taylor) The Department of Chemistry and Biochemistry has provided a sense of home for me on campus over the past three years. I joined the department at the end of my freshman year, switching into the biochemistry program. After meeting students, faculty, and staff in the department, I knew this was a community I wanted to be part of. I reached out and got involved through the CBC Ambassadors and Peer Mentor Program. Through CBC Ambassadors, I’ve been able to show prospective students the ins and outs of our department and what it looks like to be a Wildcat studying biochemistry or chemistry. Through the Peer Mentor Program, I’ve made invaluable connections supporting first-year students as they adjust to college—but my mentees have also supported me when I’ve struggled.

Samuel Ellis

That mutual support speaks to the heart of this department, which thrives on students lifting each other up. CBC has created collaborative environments inside and outside the classroom, bringing the whole community together: faculty, staff, undergraduate students, and graduate students. At CBC ice cream socials, I’ve enjoyed an ice cream sandwich while chatting with PhD candidates nearing the end of their programs. These conversations with more experienced students have significantly informed my decisions about what I want to do after graduation. This community has given me so much during my time here, and I’m grateful I’ve been able to give even a fraction of that back. Felicia Escalante

STUDENT ADVENTURES IN RESEARCH Alice Miranda

Summer study in Emilia-Romagna, Italy This summer, I had the opportunity to study abroad in Modena, located in the Emilia-Romagna region of northern Italy. The program focused on Italian language and culture, and it allowed me to experience daily life in a part of Italy known for its history, art, and incredible food. Every morning began with a cappuccino, rich espresso topped with warm, velvety milk, often paired with gnocco fritto, a local specialty made of airy fried dough served with prosciutto or cheese. Meals quickly became one of the best parts of my time there. I tried piadina al prosciutto cotto, pizza margherita, creamy tiramisu, and of course, pistachio gelato that I am convinced tastes better in Italy than anywhere else. Evenings often included an aperitivo like a bright orange spritz, enjoyed outdoors in the warm summer air. As part of our coursework, we explored the cultural and artistic heritage of the region. We visited Villa dei Capolavori, home to the Magnani-Rocca Foundation near Parma, which houses an impressive collection of Italian art surrounded by green parkland. We also traveled to the nearby towns of Langhirano and Torrechiara, where we walked through Cobblestone Streets, admired historic architecture, and toured the medieval Castello di Torrechiara that overlooks the countryside. Toward the end of the trip, we spent time along the Riviera, relaxing on the beach and swimming in the calm blue waters of the Adriatic Sea. It was the perfect way to appreciate another side of Italian life, one centered on rest and togetherness. Studying in Emilia-Romagna taught me that learning happens everywhere, not just in the classroom. It was an experience that deepened my appreciation for culture, food, and history, and reminded me how meaningful it can be to slow down and fully take in the world around you.

Summer Study in Leipzig Germany During the past summer, I attended the Summer Study in Leipzig program. I had fun experiencing German learning through casual, everyday experiences while also practicing in a classroom setting. I forged strong friendships through the tandem partner program; strong enough to convince me to extend my stay beyond the end of the class. The most fun I had was traveling to and exploring new cities to see all of what Germany has to offer. My main motivation to study in Leipzig was to see how school in Germany compares to the US to see if I would be interested in pursuing my PhD for Biochemistry in Germany. Potsdam is one of my favorite cities that I travelled to. The massive Prussia palaces in the city are beyond any architecture I could see in the US. The best museum experience was taking a guided tour around a former Stasi prison in East Berlin. The tour guide had actually been incarcerated there for protesting, a fact I found particularly powerful while looking around the former prison.

St. Jude Children’s Research Hospital This summer, I was a Pediatric Oncology Education (POE) Student at St. Jude Children’s Research Hospital. The POE program is an 11-week long research internship that offers students the ability to perform translational research of their interest, shadow physicians, scientists, and St. Jude Faculty and attend daily lectures on recent advances in pediatric cancer research. I performed research in the Leggas Lab, which focuses on characterizing Ewing sarcoma, a solid tumor cancer of the bone, along with optimizing and testing small molecule inhibitors that target the unique genome of Ewing sarcoma. My work focused on characterizing the differences in metabolic activity between Ewing sarcoma and similar aggressive cancers using metabolomics. I identified unique metabolites specific to certain Ewing sarcoma cell lines as well as metabolites directly related to drug treatments administered to the cancer cells. Another focus of my work was exploring the potential synergistic or additive effects of combination therapies that target the fusion oncoprotein that is the primary driver of Ewing sarcoma. It was such a privilege to have access to so much cutting-edge technology that is specifically tailored to curing pediatric cancers as well as being able to experience the epitome of translational research¬—patients receive care in the same building that research is done! This experience has opened my eyes to the insidious challenges of pediatric cancer as well as the phenomenal work being done on all fronts to overcome these challenges.

Attending the 2025 American Chemical Society (ACS) Conference What an incredible experience attending my first American Chemical Society (ACS) conference at ACS Spring 2025 in San Diego! It was an amazing opportunity to present my research on magnetic polymer nanocomposites and engage with scientists leading the way in polymer chemistry and materials science.

THE CATALYST ONLINE | CBC ALUMNI MAGAZINE

Presenting my talk, “Self-assembly of well-defined magnetic polymer composites via surface-initiated atom transfer radical polymerization”, in the Polymeric Materials: Science and Engineering Division was both exciting and rewarding. I loved sharing how controlled polymerization strategies can precisely tune nanoparticle interactions to enhance magneto-optical properties—and the discussions and connections that followed made it even better! Attending the ACS conference for the first time was truly inspiring. Seeing the breadth of cutting-edge research, exchanging ideas with fellow scientists, and experiencing the energy of such a large and collaborative community reinforces why I love this field. There’s nothing quite like being surrounded by people who are just as passionate about chemistry and innovation! I have left this conference with new ideas, fresh perspectives, and a deeper appreciation for the incredible work being done in this field. And I am looking forward to continuing these conversations and collaborations. .

Attending the 2025 American Chemical Society (ACS) Conference I earned the privilege to attend the American Chemical Society Spring 2025 Meeting in San Diego, CA. On my first day, I listened to oral presentation sessions on organic chemistry topics, my favorite being the asymmetric synthesis session with speakers from pharmaceutical companies. Their talks showcased how they streamlined the synthesis of various drugs and drug candidates. The field of enzymatic catalysis is very interesting, and I am grateful I got the opportunity to listen to researchers in the top of this field. The rest of the weekend was spent presenting my research at the undergraduate poster sessions and meeting with fellow chemists who all had the same passion.

Presenting at the 2025 BioPhest This semester I had the honor of presenting at BioPhest, a conference hosted by the ASU Center for Biological Physics. I initially applied to present a poster to share my research on biophysical simulation with applications to drug discovery However, A week before the event, I received an unexpected invitation to upgrade from a poster to a 20-minute oral presentation. I jumped at the opportunity to practice my skill of conveying my research on a bigger platform to an audience of experts from across Arizona and California. While attending presentations and poster sessions, I learned more about computational models of thermodynamics and biomacromolecules. I was particularly struck by the high level of accuracy some projects achieved through molecular dynamic simulations, including solvent conditions and membrane lipid composition. Through this experience, I was able to gain exposure to techniques that I was previously unfamiliar with and that could be applied to my current and future research.
