MESSAGE FROM THE CHAIR Dear alumni, friends, and members of the UF ChE community,

Carlos M. Rinaldi-Ramos, Ph.D. Department Chair & Dean’s Leadership Professor

Despite the lingering challenges of the pandemic, it has been exciting to watch as faculty, students, and staff have returned to campus to interact in classrooms, laboratories, and social and professional events, experiences that are the hallmarks of a university education. Students again interact face to face in lecture and laboratory courses and study groups. Student organizations have resumed their activities that are so important to developing lifelong networking and professional skills. Laboratories are buzzing with new discoveries and technologies. Chance encounters in hallways again result in new ideas and discussions among faculty and students. We’ve transitioned to a hybrid weekly seminar where we’ve hosted invited speakers from around the country either in person or virtually, and our faculty and students have had opportunity to attend national and international conferences and visit peers at other institutions. In short, it is great to see a return to the vibrant intellectual and cultural environment that characterized our department prior to the pandemic.

We are delighted to highlight some of the news and events that characterized the previous year.

In this issue we honor contributions by our faculty and alumni in building a supportive environment in our program and beyond.

We honor Helena Hagelin-Weaver, Ph.D., an associate professor who founded and stewarded the Women in Chemical Engineering Program for the past 20 years, supporting our women students and faculty through social, professional, and peer mentoring activities (page 16). We also highlight Sindia M. Rivera-Jimenez, Ph.D., an affiliate assistant professor who received the inaugural AIChE IDEAL Star award in recognition to her contributions in support of the inclusion, diversity, equity, anti-racism, and learning goals of our professional society (page 14). Finally, we honor Jayant Shroff (B.S. ChE ’65) and his family, whose Shroff Family Foundation scholarship endowment is the largest providing financial support to our students, and for their philanthropic and community service contributions at home and abroad (page 30).

We also celebrate the continued growth and success of our faculty. We welcome new assistant professors, Josh Moon, Ph.D., and Juan Manuel Restrepo-Flórez, Ph.D., who will pursue research clean energy and water, and sustainability (page 4). We are also seeing tremendous growth in biomolecular engineering research in our department. Carl Denard, Ph.D., an assistant professor, will pursue use of machine learning and high throughput screening to reprogram proteases with support from the National Institutes of Health (page 5). Fan Ren, Ph.D., a distinguished professor, and Piyush Jain, Ph.D., an assistant professor, continue development of two distinct approaches for rapid testing for viruses and other pathogens (pages 6 and 10). Yeongseon Jang, Ph.D., and Dr. Denard aim to design minimal synthetic cells capable of sensing and self-manipulation with support form the National Science Foundation (NSF) (page 12). We hope you enjoy learning about these projects and other faculty honors and awards.

Our students continue to make us proud. Three received highly competitive NSF fellowships (page 18), while many others won accolades at local, national, and international venues (pages 19-21).

This year also saw changes to our staff. Deborah Sandoval retired after 38 years of service in various roles and Cynthia Sain retired after nearly 20 years as the department’s sole undergraduate academic advisor. We thank them for their dedication and contributions. We also welcomed Gabrielle Donalson, who will serve as one of our graduate academic advisors.

As always, we are grateful for the support from our alumni, in time, talent and treasure. Marissa Dockendorf (Ph.D. ChE ’05), shared her career progression and insights gained over 14 years in the pharmaceutical industry as the keynote speaker of the annual GRACE symposium (page 28). Students received numerous department scholarships and awards thanks to the support of our alumni (see pages 22-23). To learn more about how to support the department please refer to page 26.

I hope you enjoy reading this magazine and I look forward to hearing from you or seeing you at an upcoming event.

Sincerely,

Carlos M. Rinaldi-Ramos, Ph.D.

DENARD TO USE HIGH THROUGHPUT FUNCTIONAL SCREENING AND MACHINE LEARNING TO REPROGRAM PROTEASES Carl Denard, Ph.D. , an assistant professor, was awarded a grant from the National Institute of Health and the National Institute of General Medical Sciences to combine, for the first time, machine-learning tools, next-generation DNA sequencing, and a yeast-based high-throughput functional screen to accelerate the isolation and design of protein-based protease modulators.

The functional selection will perform two tasks: select nanobodies from synthetic libraries based on a desired function and elucidate where a nanobody binds to a protease to elicit that function. These experiments will generate high-quality datasets that will train machine-learning algorithms to predict the potency, selectivity, and mechanisms of nanobody-based modulators based on their sequence features.

“This machine-learning-aided strategy will accelerate the discovery of rare and potent protease modulators and bypass the limitations of structure-based methods.

Furthermore, curated datasets of protease modulatory nanobody sequences will provide reference and design guidelines for future experimental and in silico campaigns,” Dr. Denard said.

This work is of significant interest to biomedical research and public health and includes proteases relevant to Hepatitis C virus, cancer, COVID-19, Alzheimer’s disease, and diabetes. The research will provide a foundation to answer fundamental biochemical questions on how synthetic ligands can map and modulate the functional landscape of proteases and other protein-modifying enzymes.

UF RESEARCHERS HELP DEVELOP HIGHLY ACCURATE, 30-SECOND CORONAVIRUS TEST With any highly infectious disease, time can be a killer.

It is crucial to get a test result for a pathogen quickly, lest someone continue in their daily lives infecting others.

And delays in testing have undoubtedly exacerbated the COVID-19 pandemic.

Unfortunately, the most accurate COVID-19 test often takes 24 hours or longer to return results from a lab.

At-home test kits offer results in minutes but are far less accurate or sensitive.

Researchers at the University of Florida, however, have helped developed a COVID-19 testing device that can detect coronavirus infection in as little as 30 seconds and as sensitively and accurately as a PCR, or polymerase chain reaction test, the gold standard of testing. They are working with scientists at National Yang Ming Chiao Tung University in Taiwan.

Fan Ren, Ph.D., a distinguished professor in the Department of Chemical Engineering, said the device could transform public health officials’ ability to quickly detect and respond to the coronavirus — or the next pandemic.

UF has entered into a licensing agreement with a New 6

Fan Ren, Ph.D., Distinguished Professor

Jersey company, Houndstoothe Analytics, in hopes of ultimately manufacturing and selling the device to medical professionals and consumers.

Like PCR tests, the device is 90% accurate, researchers said, with the same sensitivity, according to a recent peer-reviewed study published in the Journal of Vacuum Science & Technology B. “There is nothing available like it,” said Josephine Esquivel-Upshaw, D.M.D., a professor in the UF College of Dentistry’s department of restorative dental sciences and member of the research team that developed the device.

“It’s true point of care. It’s access to care. We think it will revolutionize diagnostics.”

The device is not yet approved by the U.S. Food and Drug Administration. First, researchers said, they have to ensure that test results are not thrown off by crosscontamination with other pathogens that might be found in the mouth and saliva. These include other coronaviruses, staph infections, the flu, pneumonia and others. That work is ongoing.

The hand-held apparatus is powered by a 9-volt battery and uses an inexpensive test strip, similar to those used in blood glucose meters, with coronavirus antibodies attached to a gold-plated film at its tip. The strip is placed

FACULTY NEWS on the tongue to collect a tiny saliva sample.

The strip is then inserted into a reader connected to a circuit board with the brains of the device.

specific proteins that could be used to diagnose other illnesses, including cancer, a heart attack and immune health.

If someone is infected, the coronavirus in the saliva binds with the antibodies and begins a dance of sorts as they are prodded by two electrical pulses processed by a special transistor. A higher concentration of coronavirus changes the electrical conductance of the sample. That, in turn, alters the voltage of the electrical pulses.

Dr. Ren and his team had been developing semiconductor-based sensor devices long before COVID-19 for nonmedical purposes.

The voltage signal is amplified a million times and converted to a numerical value — in a sense, the sample’s electrochemical fingerprint. That value will indicate a positive or negative result, and the lower the value, the higher the viral load. The device’s ability to quantify viral and antibody load makes it especially useful for clinical purposes, researchers said.

The product can be constructed for less than $50, Esquivel-Upshaw said. In contrast, PCR test equipment can cost thousands.

He noted that he is inspired in his work by the recent death of his wife, which was unrelated to COVID-19. He connects his grief to the mourning of the world at large.

“Almost a million people have died of COVID” in the United States, Dr. Ren said. “Those are so many tragedies. Old people. Young people. You name it. I said, ‘No, that’s it.’ That is too much.”

He said several institutions have worked on devices using a field effect transistor, or FET, like that found in the COVID-19 testing device his team is developing.

But those devices are basically one-offs — a sample is applied directly to the FET, which means the transistor is not reusable and must be discarded.

The research team also is studying its ability to detect That makes those devices expensive and impractical for mass testing, Dr. Ren said.

Then he hit on the idea of separating transistor from sample, like blood glucose meters that use test strips to collect a drop of blood after a lancet pierces a finger. This innovation, Dr. Ren said, makes the UF device unique, affordable and easy to use.

Dr. Ren said the device could be used for venues with large crowds, such as concerts, sporting events, classrooms, in addition to medical settings. Researchers say the unit would also provide access to accurate, inexpensive testing in rural areas or in developing nations.

And the personal uses, researchers say, are limitless — parties, baby showers, and other small gatherings.

The motherboard of a COVID-19 rapid testing device that UF Health researchers helped develop is seen here. The device can return a coronavirus test result as accurately and sensitively as the gold standard of testing, a PCR test, in 30 seconds.

“Yes or no. You’re infected or not infected. You get the answer right away,” said Dr. Ren. Written by Bill Levesque

NEW COVID TEST CAN QUICKLY DETECT VARIANTS UF researchers have invented a test that can determine within 10-15 minutes whether patients test positive for COVID and, if so, which of the five known variants of concern they have.

The research, published in The Lancet’s eBioMedicine, involves the use of a simple heating device and a cellphone. The team also used a new form of CRISPR — a means of finding and targeting a specific section of genetic material inside a cell — to quickly and effectively diagnose COVID and learn which variant of concern is in a patient sample: alpha, beta, gamma, delta, or omicron.

The finding could provide policymakers with vital information about when to require masking and prepare hospitals for a wave of infections. It could also allow patients and family members to prevent or treat a particular variant more effectively.

“For the medical and research community, knowing which variants are emerging is extremely important,” said corresponding author Piyush Jain, Ph.D., an assistant professor and the holder of the Shah Rising Star Professorship in the Department of Chemical Engineering.

“If an especially serious variant like delta or a genetically similar variant, such as deltacron, arises in the future, work like this discovery will 10 UF | DEPARTMENT OF CHEMICAL ENGINEERING

Piyush K. Jain, Ph.D., Assistant Professor and holder of the Shah Rising Star Professorship

help us track it earlier.”

The team, including professors Marco Salemi, Ph.D., Rhoel Dinglasan, PhD, MPH, MPhil, John Lednicky, Ph.D., and their lab members from the Emerging Pathogens Institute, made the findings in collaboration with two bioscience engineering companies registered in the Czech Republic.

The companies helped the researchers engineer a prototype that could function at home, in a clinic, or in the field.

Current tests for determining COVID variants take several days to perform, which is why patients typically don’t learn which variant they have.

Advancing on recently published work, including by Long Nguyen, a Ph.D. candidate and the first author of the study, the UF team is the first to investigate the new heatloving CRISPR technology, which manages to combine speed, accuracy, and variant identification by amplifying and detecting coronavirus genetic material in one step.

The team also created a version of the test that can potentially be used at commercial testing centers, or even at home, and can be stored at room temperatures for weeks and activated by adding water.

The researchers validated the test in hundreds of clinical

samples, detecting all five variants with 97% accuracy within 30 minutes.

Dr. Jain, who says he hopes the product can be brought affordably to market soon, also worked with Dr. Dinglasan, a professor of Infectious Diseases & Immunology, and others to establish a startup called Genable Biosciences, LLC, centered around finding partners to manufacture and commercialize the new product.

Such groundbreaking and interdisciplinary work helps to prepare for future infectious disease outbreaks, said Dr. Salemi, a professor of pathology and member of the research team.

“Requiring expertise in biochemistry, molecular virology, and genomics, this work is an example of how the COVID pandemic has fostered collaborative research to unprecedented levels,” Dr. Salemi said. “I think what we have learned about rapid detection and surveillance of fast-spreading and mutating pathogens like SARS-CoV-2 will be crucial to face the challenge of future pandemics with strong intervention measures already in place.”

JANG AIMS TO DESIGN MINIMAL SYNTHETIC CELLS CAPABLE OF SENSING AND SELF-MANIPULATION Yeongseon Jang, Ph.D., an assistant professor, has received a National Science Foundation (NSF) grant to design minimal synthetic cells capable of sensing and selfmanipulation. In this project, Dr. Jang will collaborate with Carl Denard, Ph.D., an assistant professor, and Seok Hoon Hong, Ph.D., an associate professor at the Illinois Institute of Technology. This project combines the researchers’ expertise in polymer self-assembly, protein engineering, and cell-free synthetic biology for novel synthetic cell development.

“The development of synthetic cells is of great interest to identify the minimal requirements for cellular processes and to enable a range of novel biomedical applications. Among diverse cellular functions, sensing is one of the central functions in how living cells make decisions for biochemical synthesis. Proteins are essential biological building blocks in living cells to mediate cellular functions such as sensing, signaling, and cascade reactions, but mimicking complex cell functions using proteins is still challenging due to difficulties in the incorporation of functionally folded proteins into synthetic cell membranes with precise control.

This project aims to create minimal synthetic cells that incorporate sensor proteins at membranes and enable self-manipulation by rational design and engineering of recombinant protein building blocks,” Dr. Jang said.

The researchers will demonstrate these functions by designing sensory fusion proteins that can selfassemble into vesicles and building transmembrane signal transduction systems with intracellular actuation capabilities. This project will create a new type of synthetic 12 UF | DEPARTMENT OF CHEMICAL ENGINEERING

cell, self-assembled globular protein vesicles, exhibiting sensory proteins in cell-like membranes with tunable permeability and fluidity. One of the cell-like functions will be demonstrated by integrating synthetic biology and protein engineering into the protein vesicle platforms, which will enable the self-maintenance of the synthetic cells by synthesizing its components autonomously.

“Ultimately, we aim to achieve programmable signal transduction and amplification cascades in protein vesicles upon sensing. Successful integration of cell-free protein synthesis into the protein vesicles capable of sensing will be the stepping-stone to enable the self-manipulation of synthetic cells. New biological and clinical applications could be envisioned for treating diverse human diseases based on manipulating protein functions in minimal cell structure.

More importantly, this project will help to address questions on how to leverage synthetic systems for sophisticated biological reactions happening in living cells.” Dr. Jang said.

RIVERA-JIMÉNEZ RECOGNIZED WITH AICHE IDEAL STAR AWARD

Sindia M. Rivera-Jiménez, Ph.D., an instructional assistant professor in the UF Department of Engineering Education and an affiliate faculty of the Department of Chemical Engineering, was recognized by the American Institute of Chemical Engineers (AIChE) Societal Impact Operating Council with the new IDEAL Star award.

Dr. Rivera-Jiménez’s programming on “Unconscious Bias” was selected as one of two winners for the inaugural award that recognizes those who have created and executed outstanding programming that serves to further AIChE on the Inclusion, Diversity, Equity, Antiracism, and Learning (IDEAL) path.

AIChE believes that all who wish to be a part of the chemical engineering community should have equal opportunity to pursue and achieve success. It also proposes an IDEAL Path for progress, in an environment characterized by inclusion, diversity, equity, anti-racism, and learning.

“Dr. Rivera-Jiménez is a faculty member with a great compassion for all students.

She is a leader in the Department of Engineering Education in ensuring everything we do, including our teaching, provides access and equity to all our students. The award is a wonderful 14 UF | DEPARTMENT OF CHEMICAL ENGINEERING

recognition of this work at the national level,” said Hans van Oostrom, Ph.D., founding chair and associate professor of the department of engineering education.

In addition to this recognition, Dr. Rivera-Jiménez will be invited to participate in a virtual panel to discuss developing successful IDEAL programming.

“Dr. Rivera-Jiménez created a workshop that guides participants to understand how unconscious bias is manifested, its negative impact, and strategies for avoiding pitfalls and lessening its frequency. So far, the workshop has been offered at the spring and fall 2021 AIChE meetings, and it was highly successful both times,” said Spyros A. Svoronos, Ph.D., Harry and Bertha Bernstein Professor and Undergraduate Program Coordinator in the Department of Chemical Engineering.

Dr. Rivera-Jiménez’s research includes agency in engineering communities (e.g., faculty, design teams, organizations), action research, curricular implementation of problem-solving pedagogies in process design using simulations, collaborative and inclusive environments in engineering teams, K-12 Outreach in product design, and professional development for industry and academia.

BUILDING A COMMUNITY FOR WOMEN IN CHEMICAL ENGINEERING Identifying a need for female role models and mentors in Chemical Engineering at UF, Helena HagelinWeaver, Ph.D. , an associate professor, created an informal mentoring program that has grown significantly over the last 20 years.

“I realized during my postdoctoral years how fortunate I had been to have female role models during my Ph.D., so I wanted to make sure that our female students have access to female faculty mentors or role models,” said Dr. Hagelin-Weaver. “This initiative has since grown into a formal mentoring program with several female faculty mentors.”

When Dr. Hagelin-Weaver started as a Research Assistant Professor in the department, she wanted to make sure that female Ph.D. students had interactions with female faculty. It was also important to her to give students a platform to bring up potential issues that they might not want to talk about with their male advisors.

Initially, meetings were informal social events, where they met for coffee several times a year and talked 16 UF | DEPARTMENT OF CHEMICAL ENGINEERING

about topics of interest.

The Women in Chemical Engineering Mentoring Program was formally initiated during the 2004-2005 academic year, during the tenure of Jennifer Curtis, Ph.D., a former department chair and professor.

During that time, the female Ph.D. students had a female department chair and role model. Dr. Curtis was very supportive of the mentoring efforts.

The department started to sponsor the meetings, and Dr. Hagelin-Weaver would invite female Ph.D. students to meetings once or twice a semester. She also initiated an annual Christmas gift exchange, and the group would meet and celebrate when one of the students graduated. The main goals of these meetings were getting to know other female students and faculty and provide informal mentoring.

When new female assistant professors were hired, Dr. Hagelin-Weaver began to formalize the program and the meetings. It was during this time that a new name for the program was also introduced: Women’s Advancement and Mentoring (WAM) committee.

FEATURED ARTICLE

“The Women’s Advancement and Mentoring committee played an influential role in my professional and personal development while I was a Ph.D. student, and the members have continued to serve as friends and mentors as I moved into my next role. I will always be grateful that Helena had the vision and initiative to establish and grow such a supportive community within the department.”

- Mykela Deluca, Ph.D. ’22 Postdoctoral Researcher, Purdue University

They expanded the program to first include female Master’s students and are discussing ways to include female undergraduate students. The topics of the meetings have evolved to include resume writing and how to give impactful presentations. Before the pandemic they also discussed ways to network at AIChE, and hosted a diversity discussion after watching the movie, Picture a Scientist.

In fall 2022, Dr. Hagelin-Weaver passed the leadership role to Janani Sampath, Ph.D., an assistant professor.

“Helena founded the Women in Chemical Engineering group at UF. This laid the foundation for regular meetups and professional development events which fostered a sense of community among female graduate students and faculty. This in turn led to the creation WAM, of which Helena is an active member. Without Helena’s efforts, WAM would not exist in its current form, and we are grateful for the initiative that she took early on in establishing this community,” said Dr. Sampath.

“It was very important that when I was a Ph.D. student figuring out what lab I wanted to research with, I found a lab that either had female representation or was actively trying to support female Ph.D. students. That was something that was (and is) very important to Helena as well and was one of the reasons I chose to work with her. As Helena’s first female Ph.D. student, I was excited to be in the lab because she was excited to have me in the lab. Helena always fostered my growth and inclusion in other career and personal development activities on campus. I always felt supported and championed by Helena: she was honest with me about a career in academics and while that isn’t the career trajectory I chose Helena actively disseminated my resume and helped connect me with the job I still currently have.”

ALUMNI UPDATE

ALUMNUS AWARDED 2021 AMERICAN HEART ASSOCIATION POSTDOCTORAL FELLOWSHIP Qiao Zhang, Ph.D., (Ph.D. ChE ’18), was awarded the 2021 American Heart Association Postdoctoral Fellowship. With this award, he will study how cellular force, which is transmitted by the LINC complex, the protein complex associated with both inner and outer membranes of the nucleus (LINC complex), to the nucleus, could contribute to the early development of cardiovascular disease. Dr. Zhang will use Hutchinson-Gilford progeria syndrome as a model system.

Dr. Zhang’s research interests focus on testing novel approaches to differentiation iPSCs to endothelial cells, finding out how preexisting adaptive immunity to Cas9 proteins could affect CRISPR-Cas9 based gene therapies in human muscular dystrophy, and identifying how abnormal cellular and nuclear force distributions could contribute to cell or tissue dysfunctions in Hutchison Gilford Progeria Syndrome.

Dr. Zhang is originally from Guangzhou, China. He received a B.S. in chemical engineering from the University of Minnesota, Twin Cities in 2009, and a Ph.D. from the University of Florida in 2018. He is a postdoctoral fellow at Duke University in the lab of George A. Truskey, Ph.D. The American Heart Association is one of the largest funding organizations for cardiovascular medical research.

solutions in clinical programs to address key drug development questions. Dr. Dockendorf received her B.S. in Chemical Engineering from the Illinois Institute of Technology, her M.S. in Biomedical Engineering, and Ph.D. in Chemical Engineering from the University of Florida.

Q: What was the best aspect of your experience at UF CHE? I had such a wonderful experience as a graduate student in the CHE department that it is hard to pick a “best.” I worked on an interesting Ph.D. project, had many opportunities to publish and present my research, and left grad school well-prepared for my career ahead. I also made some of my closest friends to this day during my time there!

Q: What is your favorite memory of your time as a student?

I have so many fond memories from my time as a graduate student. I actually met my husband in a class at UF! One moment that I often reflect on that may be more relevant for current students is related to an Intro to Engineering class I used to TA. In that class, I would give a presentation about chemical

ALUMNI SPOTLIGHT

engineering to undecided undergraduate engineering majors, which included discussion on how chemical engineers were the “universal engineer,” with many different possible career paths. At the time I didn’t realize how true that was! My own career path has not involved taking what would be considered “traditional chemical engineering” roles, and I know many people who are chemical engineers by training that are now working in a variety of different areas. It has been wonderful to see what I used to lecture on play out in practice in my own life!

I have many friends from my time at UF that I keep in touch with and a few that have ended up working at the same company as me (Merck & Co. Inc.). I have been a recruiting ambassador for my company and enjoy meeting others from the Gator Nation at conferences (back when they were in-person), and I can’t wait to do so again when conferences return to being in-person!

Q: Who influenced you during your time at UF?

One of the challenges I faced was of a more personal nature. My husband and I had the classic “two body” problem in trying to find two Ph.D. level jobs in the same location. My husband found a job in California, and after having worked at another company I wanted to return to Merck & Co. Inc. in Pennsylvania. I asked about remote work as a possibility, and fortunately, had a very supportive supervisor that hired me back and allowed me to work remotely from California. I ended up working remotely for over 10 years, first from California and later from Florida. I’m very grateful that my company supported this remote work arrangement and I have learned that it is best to simply ask for what you want to enable your success and work/life balance.

My graduate research advisor, Dr. Anuj Chauhan, has and continues to be a great mentor to me. During my time as a graduate student, he helped me to develop my research, experimentation, and modeling skills. Beyond the technical aspects, he encouraged me to present my research in various symposia and conferences and hone my presentation skills. He also helped me to find a summer internship during my time as a student that later helped land me a job at that same company, and provided me with a lot of career advice, both during my initial job search as well as throughout my career.

Q: How did this time influence your career?

During my career I have worked in pharmaceutical R&D in the areas of quantitative pharmacology & pharmacometrics, ocular drug delivery, and now digital medicine. My experiences at UF really opened my eyes to many different possible career options. It was during my graduate research that I worked on developing a physiologically based pharmacokinetic model and first became aware of the field of pharmacometrics as a career path. I also learned a lot about ocular drug delivery from my advisor and others in my lab, which is a field in which I also later worked.

Q: How have you stayed connected to the Gator Nation?

Q: Have you faced a challenge in your career and how did you overcome it?

Q: What advice do you have for current students?

Use this time to learn and explore various things you are interested in. Take advantage of opportunities to get involved in the wider scientific community and seek out mentors that can help you navigate your job search and offer career advice. Take every opportunity you have to present your research findings and develop your presentation skills; the GRACE symposium is a great forum for this! Most importantly, enjoy the journey, pursue a career path that you are truly excited about, and don’t be afraid to change jobs or even career paths to suit your personal and professional needs.

THE SHROFF FAMILY CREATES A LEGACY OF GIVING After graduating from the University of Florida in 1965 with a bachelor’s degree in chemical engineering, and then earning his master’s in engineering and an MBA, Jayant Shroff worked for 10 years in R&D jobs at Fortune 500 companies including Bell Labs, AT&T, Lucent Technologies, and ExxonMobil Research and Engineering. His professional career in the U.S. spans over four decades and he has held many executive positions. He married his best friend, Dr. Yogini Shroff, a practicing physician. Both emigrated to the United States in the 1960s, and together they enjoyed growing their successful careers.

The Shroff family is focused on mentoring young people to be leaders through Shroff Family Foundation scholarships in Chemical Engineering at University of Florida and Engineering college scholarships at Sarvajanik Education Society in Surat, Gujarat. The Shroff Family also co-founded Yuva Pragati, a non-profit organization dedicated to educating the impoverished rural youth of Gujarat, India. At home in Metuchen, N.J., the Shroff’s community service involves board membership at a local senior center and food bank.

Q: What is your favorite memory of your time as a student?

In 1964, I choreographed an Indian folk dance called Raas from the state of Gujarat in India for an international dance competition. We had eight participants who had no idea about dancing. It required a lot of improvisation. Anyway, we came first among 10 entries! I will never forget the moment when the judges announced the winners. At midnight, we all went out for ice cream to celebrate. These outings brought a lot of joy.

Another memorable day was in the spring trimester in 1965, when I was called into Dr. Charles Hukaba’s office. Dr. Hukaba offered me a graduate assistantship at Drexel University for a master’s degree in chemical engineering. Dr. Hukaba had accepted the position of Department Chair at Drexel beginning in the Fall 1965.

I was overjoyed with this unexpected offer and decided to accept it.

I was quite shy when I first enrolled at UF. However, by the time I graduated I developed confidence in my abilities, acquired excellent communication skills, and

enhanced my critical thinking and analytical skills. This confidence helped me to be successful throughout my professional career.

Q: What advice do you have for current students?

Success is 90% hard work, 5% intelligence and 5% luckbeing in right place at the right time.

Focus is another dimension for success.

Capture every opportunity you get and explore it to best of your abilities.

Be kind and humble, help others, it will give you a lot of joy and fulfillment in life which any amount of money cannot give. The bounty will come back to you some day.

This is from our own experience of more than 40 years of giving.

Q: What impact do you hope your gift has for UF ChE students?

We have always believed that education is the first step toward transformation and success in life. And we are very proud that we got an opportunity to assist young people in achieving their dreams.

Q: If you could change the world, what would you do?

We would change the definition of success from acquiring

a lot of wealth and resources to being kind, respectful to each other, being a good citizen and concentrate on being happy and content. In the schools we support, we teach these qualities to children at an early age and call it “VALUE EDUCATION.” Q: What makes you most proud?

Our desire and ability to help more than 100,000 children with no means in remote villages of India acquire good education, become valuable citizens, and achieve economic independence.

For the past 25 years or more all celebrations (birthdays, anniversaries, graduations, new job offers, etc.) in our family have started with appropriate donations to a worthy cause. Our daughters celebrated our 50th wedding anniversary (we did not want a big party) by building a large assembly hall in a residential school for children of migrant workers in the village of Wanghadhra in Gujarat, India.

With the equal support of my wife Yogini and daughters Viraj and Radhika, our son-in-laws Ojas Mehta and Seth Bair, and few like-minded friends we have embarked on this mission since 1982.
