20 Bringing Sustainability Home Fernando Salud ’17 tackles sustainability challenges in the climate-change hotspot of the Philippines.

My profile in the spring magazine brought up a lot of (good!) emotions, especially given the roundabout path I took toward getting into the College in the first place. I wasn't the greatest student in high school, but I tried really hard and fumbled my way through. I knew, when I first heard about Mudd, that this would be a perfect fit for my brand of weirdness. However, they (and every other college I applied to!) rejected my application. And so I watched my friends all go off and start their college adventures and I just went back to working at The GameKeeper, a board game store in the Main Place Mall near my home in Orange County, California. I took classes at Santa Ana Community College. I sulked for a bit. But I put that aside and learned about how sometimes if you want something, you may not get it. I learned about the skills I have that overcame my natural lack of Raw Intelligence and Insight, skills like an ability to just keep trying, asking for help, and putting aside ego. A year later, when I reapplied to HMC, I requested an interview with the admissions committee, where I opened up about how glad I was to be given time to grow and mature. I told them what I'd done over the year to earn a spot with them. This time, they took a chance on me. I was accepted. I remember my mom calling me while I was working at the mall, and just bursting into tears in the back room, then having to collect myself and finish out my shift selling copies of Apples to Apples. So to be asked to talk about myself for the magazine is such an amazing honor, especially given how I was far from the best student there, but I was someone who tried despite poor grades, who was constantly in office hours, and who knew how important this opportunity was. –Kevin Hainline ’06 (physics)

PRESIDENT’S MESSAGE Powered by Joy along with research, summer is often a time for campus improvements, including updates to several of our residence halls and, this year, beginning preparations for the College’s new generator to be installed by the end of summer 2023. A backup power generator will provide much-needed additional coverage in the event of future power outages so that we may better safeguard important research and lab work throughout our academic complex. As I observe the activity on campus, I look back at yet another remarkable academic year filled with special moments and extraordinary accomplishments, powered by the dedication and hard work of faculty, staff, trustees and families. Students enjoyed a full year of in-person classes and research, and our first-year and sophomore students were finally able to experience residential life at Harvey Mudd for the first time since they enrolled. We navigated a winter outbreak of the Omicron variant and the multiple subvariants that persist and were able to celebrate the 214 members of the Class of 2022, our third (and final) commencement ceremony of the year. I know that, like me, you look forward to hearing about their amazing accomplishments as they enter the next phase of their lives: some in the workplace and others in grad school. Still others will become entrepreneurs,

and they have a strong set of resources in this area (page 8). Along with our graduates from the class of 2022, we’ve said goodbye to several colleagues in recent months. As you know, Lisa Sullivan (page 10) has left Harvey Mudd to become provost and dean of faculty for Mount Holyoke College after 32 remarkable years at Harvey Mudd. Engineering professor Ruye Wang retired after more than 30 years of leadership and teaching (page 9). We mourn the loss of two pioneering professors: Mack Gilkeson (engineering) and Hank Krieger (mathematics). Read more about their contributions and lasting legacies on page 9. The challenges facing today’s world are enormous: climate change, social justice issues, infectious diseases, ongoing wars in Ukraine and elsewhere. Harvey Mudd College graduates make valuable contributions to addressing these challenges as well as to making key advances in science and technology. I know that wherever they go and whatever they do, they will make a difference. Given the increasing impact of technology on every aspect of society, the world needs Harvey Mudd graduates, their STEM knowledge, curiosity and joy of learning now more than ever.

Entrepreneurship Class Inspires Startups a new entrepreneurship course is part of HMC’s effort to strengthen and expand curricular and co-curricular activities to nurture the next generation of entrepreneurs. Ten student teams pitched startup ideas to venture capitalists/judges at the conclusion of the spring 2022 class, and two teams— Athena, a modern class registration app to help students graduate, and Terra Robotics, a direct air capture product—won the chance to pitch their concepts to well-known venture capitalists. The class, led by HMC engineering professor and the director of entrepreneurship initiatives Kash Gokli, is aimed at those who would like to launch a startup upon graduation or later, students who want to join established companies and apply their entrepreneurial skills and spirit, and students who would like to be social entrepreneurs. It

had an enrollment of 63 students from each of the undergraduate Claremont colleges and CGU (73% from HMC). Mentors included Josh Jones ’98, co-founder of DreamHost and the startup incubator HMC INQ, and HMC trustees Sergio Monsalve P25 and Mar Hershenson P24. HMC alumni entrepreneurs and others shared their success stories and covered topics

of interest during class sessions while 10 student teams came up with startup ideas and worked on them throughout the semester. “I was blown away by the level of student energy, the quality and the breath of projects students worked on,” says Hershenson. “This class is an important step to inspire our students to become great entrepreneurs.”

Winning Startups

Athena Ayman Abdellatif ’24, CEO; Ammar Fakih ’24, CTO; Lucas Welsh CMC ’25, CMO/CFO; Andrew Faber ’24 (UC Riverside), senior software developer Athena is a modern class registration to help students graduate. With a focus on course preparation, student connection, on-demand tutoring and local community engagement, the Athena service would require colleges to pay a subscription per student. A key feature of Athena is Class Pages, which allows students to get more information like course syllabi and course recommendations in an organized mobile app. Abdellatif, an engineering major with a music concentration, says, “Having successful people who believe in my team and our dream has been a key aspect in our progress.”

The Entrepreneurship Summer Fellowship program places students in early stage companies for summer internships. This summer, 18 students worked with a variety of startup ventures.

Terra Robotics Ryan O’Hara ’24, Devon Overbey ’24, James Barrett ’24 Direct air capture (DAC) technology pulls CO2—the primary greenhouse gas driving climate change—from the air and sequesters it away beneath the Earth so it can no longer warm the planet. The Terra Robotics product is a DAC robot that floats on the ocean and uses hydropower and biochar to sequester carbon dioxide. O’Hara says it is sustainable, cheap to produce, produces net negative carbon emissions and aligns with cutting-edge DAC science. Terra Robotics would target 154 coastal governments around the world. Within a year or two, they hope to have a prototype that achieves the desired parameters so they can begin to scale up. O’Hara, a sophomore transfer student double majoring in environmental robotics (IPS) and math/CS, says “The class gave me the push to put something into action: using science to make the world a better place and help those who’ll be most impacted by climate change. The guest speakers and Mar Hershenson P24 gave me valuable advice on how to move my idea from theory to reality.”

Other Startup Ideas from the Class • A Slice of North– Build and operate a woodfired pizza oven at North Dorm • isoLearning– Hands-on tool for schools to help students learn complex 3-D concepts • MakeIt Pitch– Connect talented makers with creative customers • Free Market Freeway– An app that converts freeways into free markets • Vinci– Decentralize art • Community Marketz– Showcase local businesses selling sustainable and high-quality products • Goodchange– Easily donate to any number of charities in one centralized hub, streamlining the giving process • Roady– Road trip app with a social-media aspect plus guides and interfaces for hotels, camping and other stops hmc.edu/entrepreneurship

Digital Jacquard Loom thanks to a generous donation from the Class of 1996, the HMC makerspace staff was able to purchase a Jacquard loom manufactured by Tronrud Engineering (Norway) in fall 2021. After traveling on a ship for about three months, the loom arrived on campus just before spring break. Artist and adjunct professor Christy Matson, who has a decade of experience working with such looms, helped set it up and provided a workshop to show the makerspace stewards best practices so they can help other students operate the loom. The fall 2022 HSA special topics class Fibers and Materials, taught by Lindsey Preston Zappas, will use the Jacquard loom as part of its curriculum.

Upward Bound Funded Through 2027 HMC’s Upward Bound program, which has helped low-income, potential first-generation college students for half a century, has been re-funded for five years. With funding for the summer guaranteed, program director Angie Aguilar-Covarrubias and her staff transitioned—for the first time since the start of the pandemic—into in-person services with some hybrid components. She said, “I am proud of the collective impact that we have all made in our community for the last 50 years, and I am excited we get to continue this important work at Harvey Mudd College through 2027!” Upward Bound students were offered these services and opportunities this summer: • Twice-daily, four-week summer research lab opportunities with HMC professors Danae Schulz and Dan Stoebel • A partnership with the HMC makerspace; stewards taught a twice-a-week class for five weeks • Six weeks of summer programming at HMC complete with 25 daily virtual internships at the Library of Congress and The Scripps Research Institute. • A summer residential experience for 21 rising juniors at UC San Diego with daily in-person internships in La Jolla at various math and science-based labs, hospitals and institutions.

Homework Hotline Here to Stay For 13 years, the College provided Homework Hotline (1.877.827.5462) to the community thanks to private donations. Now, recognizing the invaluable resource the hotline provides to the region, the College has made the program a permanent part of its overall operating budget, assuring that local and regional students will have access to free, quality math and science tutoring for years to come. The free over-the-phone tutoring service for K–12 students, open Monday through Thursday from 6–9 p.m. PT during the academic year, has averaged 3,000 calls per academic year. Most calls to the hotline come from students in junior high and high school, with over 60 percent of callers requesting help in trigonometry, geometry or algebra. The program primarily serves the greater Los Angeles area but is open to all students who have math or science homework questions. During spring 2020, when students across the country moved

to online instruction in response to the pandemic, Homework Hotline extended its hours. Harvey Mudd tutors, who had also moved to online learning, staffed the hotline remotely from their homes in 12 states. Homework Hotline was conceived in 2010 by President Maria Klawe after she visited the successful Homework Hotline created at RoseHulman Institute of Technology. RHIT shared its system with Harvey Mudd, provided technical advice for its implementation and continues to be a valued collaborator. “The service means so much to the surrounding schools,” says Gabriela Gamiz, director of community engagement. “Funding the program permanently is the College’s way of demonstrating its importance. Homework Hotline is part of our fabric and culture, what we believe in. We want to keep on sharing the amazing passion and talent that Harvey Mudd students have for math and science with the wider community.”

Spring Retirement Engineering Professor Ruye Wang taught and mentored students at Harvey Mudd for more than 30 years. A Tianjin University graduate and former lecturer at Peking University in China, he worked on ways to enable computers to “see” the world as well as humans do, specializing in image processing, computer vision, machine learning and remote sensing. In 2008, he traveled with college presidents and other leaders from The Claremont Colleges on an historic trip to Asia to introduce the consortium and to seek areas of collaboration with officials in Singapore, Hong Kong, Shanghai and Beijing. He returned to China each summer from 2011 to 2019, to run a program with the China Studies Institute at Peking University in Beijing that provided a unique study abroad opportunity for about 80 HMC students each year. As a NASA project principal investigator, he collaborated with other scientists and provided HMC students with the opportunity to develop a smart system to help NASA analyze the huge amount of multi-spectral data collected by various NASA satellites that could help better understand the geological evolution of early Mars. He worked with JPL’s Machine Learning Systems Group to find software solutions to hard problems requiring data mining, knowledge discovery, pattern recognition, and automated classification and clustering. He is the author of the textbook Introduction to Orthogonal Transforms: With Applications in Data Processing and Analysis.

In Memoriam Engineering Innovator

Academic & Athletic Leader

The Harvey Mudd community mourns the loss of Murray Mack Gilkeson who died in April. Known for his innovative ideas and kindness, Gilkeson taught engineering at Harvey Mudd for 26 years. Gilkeson was born Feb. 8, 1922 in Augusta, Kansas. He received chemical engineering degrees from University of Southern California (B.E.), Kansas State University (M.S., 1947) and University of Michigan (M.S.E., 1951, and PhD, 1952). Before HMC, Gilkeson worked for the U.S. Navy as an engineering officer, then became a research assistant at the Engineering Research Institute at University of Michigan. After serving as an assistant professor at Tulane University for 10 years, he joined the HMC Department of Engineering faculty in 1961 and retired in 1987. In addition to teaching, Gilkeson was instrumental in the growth and development of the engineering department. He is the co-founder and co-inventor of the Clinic Program, a hands-on approach to teaching engineering in which small teams of students are given real-life design problems to solve from industry partners. This program was controversial at first because its approach opposed conventional wisdom and went very much counter to then-prevailing thinking about engineering curricula. Even with these concerns Gilkeson proved it could work leading to other institutions using the Clinic Program model. In 2012, Gilkeson was co-winner of the National Association of Engineers Bernard M. Gordon Prize for Innovation in Engineering and Technology Education, given to those who create and disseminate innovations in undergraduate engineering design education to develop engineering leaders. Gilkeson served as a consultant for companies in the chemical and metallurgical engineering fields, assisted on legal cases involving metal failures and did industrial development work in Mexico, Brazil and India.

Mathematics Professor Emeritus Hank Krieger, a beloved colleague and mentor, died on June 29. During his 37 years at Harvey Mudd College, Krieger held many leadership roles on campus, including chair of the Department of Mathematics and chair of the faculty. Within the math department, he was known for his kind, supportive and generous nature, as well as for his depth of knowledge across many fields of mathematics. He was a versatile problem solver who appreciated all areas of theoretical and applied mathematics. He served as an officer in the Naval Reserve and a mathematics instructor in the Advanced Sciences Division of the U.S. Naval Nuclear Power School. After receiving his PhD from Brown University, he became a Bateman Research Fellow then assistant professor of mathematics at California Institute of Technology before joining the Harvey Mudd mathematics faculty in 1968. An expert in probability theory and stochastic processes, he authored a college textbook, supervised countless Clinic projects and senior theses and mentored PhD students. He was also a legendary Claremont-Mudd-Scripps tennis coach and was named to the CMS Athletic Hall of Fame for his 22 years of outstanding leadership in the men’s tennis program. He was named an HMC Honorary Alumnus in 2005. Read more about Krieger and share a memory at hmc.edu/in-memoriam/hank-krieger/.

Biology 1. Joshua Tree Demography and Decomposition: Implications for Night Lizard Habitat Advisor: Stephen Adolph, Stuart Mudd Professor of Biology Student: Ihlara Gray Desert night lizards rely on fallen Joshua tree logs and limbs for habitat. Climate change is likely to reduce Joshua tree populations, potentially threatening night lizards, but little work has been done to characterize habitat in more detail and determine the severity of this threat. Students measured living and dead Joshua trees in Saddleback Butte State Park and found that the majority of habitat is provided by living trees over 120 years old and equally long-lived fallen trees that only produce high-quality habitat for a small percentage of their lifespan and decay process. Their results imply that any reduction in Joshua tree lifespan would have negative consequences for night lizards, and it would take a long time for a newly established tree population to begin producing habitat.

Mathematics 2. An Exploration of Voting with Partial Orders Advisors: Michael Orrison, professor of mathematics; Darryl Yong ’96, professor of mathematics and Mathematics Clinic director Student: Mason Acevedo How do we make fair decisions as a group? Obviously, we put things up to a vote. Not-soobviously, voting is much more complicated than one might expect at first glance. Namely, different voting systems can produce wildly different results even with the same set of ballots. Acevedo studied various voting systems and attempted to understand systems that ask voters for partially ordered preferences rather than complete ones.

Mathematics/Computational Biology 3. Improving Segmentation and Classification Scalability in Honey Bee Forage Mapping Advisor: Matina Donaldson-Matasci, associate professor of biology Student: Tom Chenlian Fu Understanding how the spatial distribution of floral resources relates to honey bee foraging efficiency is important for expanding the global populations of honey bees, effective pollinators in agriculture. To quantify such spatial distribution, Bee Lab members developed a pipeline that stitches habitat drone images into an orthomosaic, differentiating plants from the background (segmentation) and identifying plant species (classification). However, the pipeline does not scale well to different plant species and does not evaluate segmentation accuracy. This project improves scalability with a species-agnostic multifeature segmentation scheme and a deep-learning Mask R-CNN method. The project also provides the average precision metrics to comprehensively evaluate segmentation.

Chemistry 4. Synthesis of Copper, Magnesium and Zinc Complexes for Carbon Dioxide Reduction Advisor: Adam Johnson, professor of chemistry Student: Emily Y. Fok The continual rise of greenhouse gas levels has made CO2 capture and reduction into other useful chemicals an important area of study. Since CO2 is a relatively inert molecule, a catalyst is required to overcome high activation barriers for binding and reduction. Transition metal complexes, especially those that are more earth-abundant and inexpensive, are being developed for potential applications in reducing CO2. Over the past year, copper catalysts were synthesized from methodology adapted from the literature. Recrystallization of these complexes was also attempted to determine their structures. Extensive literature review was conducted to better understand the possible mechanisms of CO2 reduction to better aid future catalyst development.

Mathematics 5. Acoustic Localization in Secondary School Classrooms Advisor: Darryl Yong ’96, professor of mathematics and Mathematics Clinic director; Ilana Horn, professor of mathematics education, Vanderbilt University Student: Athena Li When teachers assign groupwork in their classrooms, they create an opportunity for the learning experiences of their students to diverge. How do teachers interact with their class during these groupwork times to ensure that relevant content is taught? Li applied techniques from acoustic localization to track how teachers move through their classrooms and pull from signal processing algorithms to automate this data visualization process.

Physics 6. Investigation of Dark Matter Interactions Mediated by Axion-like Particles Advisor: Brian Shuve, assistant professor of physics Student: Benjamin Khoury Dark matter’s composition and behavior is largely unknown, as well as the origin of its abundance; it consists of 85% of recorded matter in the universe. Because the mechanics of the reheating epoch of the universe heavily restricts this abundance from naturally arising from the Big Bang, most models explaining dark matter’s abundance also predict interactions between dark matter and regular matter. Khoury investigated a different model in which this interaction occurs through an axion-like particle as a mediator particle. He calculated the theoretical reaction rates this mechanism would have since measuring this against observed values can serve as a test of the validity of this model. If correct, the model would aid in creating new detection methods of dark matter.

Heat Transfer is Everything An expert in the exchange of thermal energy between objects, Anne Hofmeister ’76 challenges assumptions Writen by Jen A. Miller Photo by Hugh Chou

nne hofmeister ’76 still consults her first-year physics textbook: Fundamentals of Physics, by David Halliday and Robert Resnick. A pioneer in measuring heat transfer and challenging the status quo about how earth materials operate and how planets form, Hofmeister is quick to credit her time at Harvey Mudd College for having shown her the nuts and bolts of her profession. “I was taught to look at the basics, to look at assumptions and do my homework and to understand things from the bottom up,” she says. Hofmeister chose Harvey Mudd because she wanted to go to a small science school, “and California was very appealing,” she says, and very different from her home state of Ohio.

She was one of the few women in the physics department at the time and would often be the only woman in the room throughout her career. When describing Mudd from the 1970s, she said it was a different time, and not just when it came to the gender split. Unicycles were more popular on campus. Homework was more of a solo endeavor than it is today. Hofmeister knew before she got to Mudd that she wanted to study physics. “It’s fundamental and mathematical,” she says. She also had a concentration in literature, which she says helped hone her writing skills, become a better communicator and, later, an author. After graduating from HMC, she earned her M.S. in physics from the University of Illinois, then another M.S. and a PhD in geology from the California Institute of Technology. The physics degree got her interested in spectroscopy, the study of the absorption and emission of light. At Caltech, she was nudged toward Silicon Valley. She resisted because it “seemed rather boring,” she says. “I know other people wouldn’t feel that way, but it just didn’t appeal, so I moved over to earth science, and spectroscopy was the natural place to go.” She started her academic career at the University of California, Davis in geology before moving to Washington St. Louis University, where she’s been since 1994. Now a research professor in the Department of Earth and Planetary Sciences, she’s focused on understanding heat transfer, the exchange of thermal energy between objects. “Heat transfer is everything,” she says. In 2006, she introduced laser-flash analysis—the gold standard of the industry— to measurements of Earth materials. This technique quantifies heat transport across semi-transparent materials like silicates and oxides. Using a steel-welding laser, “you hit the sample with a tiny heat pulse from a laser, and you record how the temperature changes on the back side from its emissions,” she says. The analysis also includes how quickly the transfer happens. The apparatus that does the analysis is in her laboratory in the Earth and Planetary Science department at Washington University, a one-of-a kind geoscience facility. Hofmeister decided to study heat transfer from the geophysics perspective in order to help draw a clearer picture of heat transfer inside the Earth. It hasn’t always been smooth sailing. Her work has been controversial in earth sciences and astronomy, she says, because she’s

challenging basic assumptions formed prior to the 1930s that she believes are incorrect. One such assumption is that spinning stars and planets will contract and heat up. She compares this to Olympic figure skaters. As they spin,” they pull their arms in—they don’t catch on fire,” she says. “There’s this basic assumption that newly formed objects are so hot they melt, and that’s just wrong. They spin up. We can see that in the data on star spin rate.” Hofmeister’s work has been more embraced in material science because heat transfer is also critical in understanding and designing things humans build. It can help engineers determine how much and how quickly a bridge will expand in the heat, for example. Knowing heat transfer also helps with computer design, by determining how thin glass can be while still allowing a computer to cool down. “It helps us understand how the heat is moving and, as we develop new materials, we need to understand how they transmit heat,” she says. In 2019, she published Measurements, Mechanisms, and Models of Heat Transport, a textbook that offers an interdisciplinary approach to the dynamic response of matter to energy input. “It’s not the final answer, but it’s the summary of what I did for 20 years,”

she says—not final because she’s still working, researching and exploring heat transfer. In 2020, she published Heat Transport and Energetics of the Earth and Rocky Planets, which applies heat transfer to Earth, Venus, Mercury, Mars and rocky moons, trying to understand how they behave. At 68, she’s still working on that “final answer,” she says, while making sure to carve out time to play with her grandchildren, to swim and to refinish a 1985 Porsche, which she jokes “breaks down at the most inopportune times.” Looking back on her career, she recognizes that she had a steeper hill to climb than her male counterparts because she was a mother of three children, which permitted focusing on research but not simultaneously on career-advancement. A few years ago, she became involved in helping other women scientists and now coordinates the Distinguished Lecturer Program of the Association for Women Geoscientists. Nearly every day, Hofmeister is reminded of the lessons Harvey Mudd taught her about science and discovery. Instead of “dressing things up,” she goes back to the beginning and considers what an idea is rooted in and why scientists think about it the way they do. “My basic training at Harvey Mudd has led me to question a lot.” SUMMER 2022

Bringing Sustainability Home Fernando Salud ’17 tackles sustainability challenges in the climate-change hotspot of the Philippines Written by Kristin Baird Rattini Photos by Sofia Gonzalez

for fernando salud ’17, climate change is not an abstract concept. He lives in the Philippines, which consistently ranks among the countries at greatest risk from climate change. “We’re a nation of more than 7,000 islands, so sea-level rise is going to be a huge problem,” Salud says. “We’re also in the danger zone for super typhoons, like Super Typhoon Odette that struck last December. It’s only going to get worse. That is driving my passion for sustainability.” Salud works in the Manila area as a data strategy consultant for Thinking Machines, a data technology consultancy that builds enterprise cloud data platforms and deploys custom AI, along with consulting, training and coaching. The company recently began building data products for climate change mitigation and adaptation for Southeast Asia.

Salud’s passion for sustainability has motivated his career and academic pursuits ever since he watched the Al Gore climate change documentary An Inconvenient Truth when he was younger. “I was shocked,” he says, “but I was also shocked that other people weren’t as shocked by the facts as we needed to be.” He was drawn to Harvey Mudd not just by its exceptional academics but also by its mission of educating leaders who have a clear understanding of the impact of their work on society. “That was really important to me,” he says. He appreciated the synergy between the engineering department’s focus on problem solving and the need for green design solutions. “The class that opened my mind was Life Cycle Assessment,” he says. “It was the first time I was able to add rigor to my thinking around sustainability.” Former HMC professor Tanja Srebotnjak, the inaugural director of the Hixon Center for Sustainable Environmental Design (now the Hixon Center for Climate and the Environment), guided students through a product’s entire value chain, from its raw material source through production, distribution, use and disposal. “It’s a powerful tool,” Salud says. “You can quantify the environmental impacts across the different stages and see which stages are the worst offenders so you can be more targeted in your interventions.” During his senior year Clinic project for the Mission Rubber Company, he installed internet of things sensors and created a unified dashboard to evaluate energy usage of the company’s huge aging molding machines. “When they put in new energy-reduction initiatives, they’d have a testing and tracking system to monitor its effects,” he says. “I liked it because it was a clear business case for sustainability.” He approached sustainability from a different angle as part of the inaugural cohort for EnviroLab Asia. This 5C-wide initiative took the student and professor research fellows to Borneo and Singapore to study the proliferation of oil palm plantations and develop potential policy interventions to conserve forest cover and provide alternative livelihoods for farmers. At the end of 2019, Salud moved to the Philippines, where he was born and spent part of his childhood. “The Philippines has had a huge brain

drain,” he says. “I’m helping reverse that a bit by bringing here what I learned at Mudd.” He joined the consultancy Business for Sustainable Development and worked on the Zero Waste to Nature by 2030 initiative. The Philippines is among the top countries contributing to ocean plastic waste. “The trash problem is very in-your-face in the Philippines,” Salud says. “We have these beautiful beaches, but there’s a lot of plastic trash on them.” When the Philippine government threatened to issue a sudden blanket ban on single-use plastics, multinational corporations and members across the waste value chain banded together to launch the initiative and develop a plastic credit exchange. “It’s modeled

on greenhouse gas emissions trading,” Salud says. “If a particular company puts out 1,000 tons of plastic in one year, they have to pay another organization to collect and recycle an equal amount.” The proposal is still being reviewed by the Philippine legislature; there’s public pressure for its passage. In October 2021, Salud joined the growth team at Thinking Machines, which has a mission of solving high-impact problems with AI and data. Among its current projects is a climate smart aquaculture collaboration with Conservation International and Arizona State University School of Sustainability. They were awarded a research grant by Climate Change AI, a global nonprofit combatting climate change

with machine learning. Thinking Machines will use its Eco-Intelligence Solution to produce open-source code, datasets, interactive maps, analyses and research to help identify the top 40,000 most suitable hectares in Southeast Asia for a “Climate Smart Shrimp” program. The initiative will help shrimp farmers produce more food using less land area, freeing up ponds to be replanted with mangroves, which are excellent carbon absorbers, coastline protectors, erosion controllers and havens for sea life. “Thinking Machines reminds me of being at Mudd,” Salud says. “We’re a bunch of nerdy engineers who all want to apply our particular skills to solve problems that matter.”

The road to the perfect ceramics glaze began on Platt Boulevard Written by Sarah Barnes Photography by Anil Kapahi

gabriel takacs ’05 and his partner, ceramicist Andrea Wolf SCR ’05, had a frustrating problem. Wolf knew that the clay she was using required a glaze with specific properties unavailable in commercial products, so she’d begun making her own glaze using existing calculation software. But the software only helped to a point: It could tell a user what was in a glaze recipe, but it couldn't easily calculate how to adjust the recipe to achieve specific goals. After spending many fruitless hours guessing and testing, Wolf asked Takacs if he could think of a better way. Takacs, a Microsoft engineering manager, ceramicist and Harvey Mudd engineering alum, surmised that, yes, there probably was a more efficient method of making glaze recipes. After about a year of research and tinkering in their home studio in Santa Clara, California, Wolf and Takacs developed an initial glaze recipe tool that solved their problem. It was so effective that they decided to file a patent in 2018. Development continued until, after moving to Issaquah, Washington, the couple participated in HMC INQ, a mentoring program for startup companies founded by Josh Jones ’98 and Professor of Economics Emeritus Gary Evans. During HMC INQ, the pair formed an LLC and launched GlazeForge.com in 2020. “Glaze Forge gives you direct control over many aspects of glazes, not only the chemistry,” says Takacs, who earned a PhD in electrical engineering from Stanford University. “It enables artists to spend more time making art

HARVEY MUDD COLLEGE MAGAZINE

and less time being frustrated by poorly behaved glazes.” Takacs shares more about how college experiences helped mold their business and the process of making glaze. How did your college experiences lead to creating Glaze Forge?

You can almost draw a straight line from our education at HMC/Scripps to the existence of Glaze Forge. Andrea spent the latter half of her degree taking every ceramics course that the 5Cs had to offer while spending a bunch of time at HMC. The baseline knowledge/awareness of the technical fields of study are part of the spark that led Andrea to believe there was a better way to compute glazes. She also took web design at Pomona College, which has been helpful in building GlazeForge.com. From a ceramics perspective, Andrea became the studio technician for the Scripps and other 5C ceramics studios in the latter half of her degree, which gave her extensive experience mixing clay and glazes for classes. I entered the ceramics world by taking a beginning ceramics course at Scripps at Andrea’s urging. Having always been interested in the arts, I took an interest in the medium, but couldn't spend much time on it due to the HMC course load. (As a side note, I chose to

attend HMC because of its balanced curriculum between the arts and sciences.) The engineering degree at HMC exposed me to a range of topics that later turned out to be highly applicable to ceramics in general and Glaze Forge in particular. Key examples: first-year chemistry laid the basics of inorganic chemistry and chemical computations; various lab-based classes taught how to keep a lab notebook; mechanical engineering taught the mechanics of stress and strain in bulk materials; materials engineering taught about crystal growth, thermal expansion and failure modes; and, obviously, computer science deepened my programming knowledge. In addition to knowledge from HMC, my graduate studies in control and optimization were also critical to the development of Glaze Forge. However, the most salient point is that Glaze Forge is exactly the type of interdisciplinary endeavor that is enabled by a 5C education. How does the Glaze Forge process work?

Many ceramic artists end up needing to modify existing glaze recipes. There are many parallels between a traditional chemistry lab and a ceramic studio. Small-batch experiments are run to try a bunch of hypotheses, and notes are taken (with varying degrees of fastidiousness). The turnaround time for each experiment is at least eight to 12 hours because of the time it takes to fire a kiln. To save time, ceramicists will often perform a “line blend” wherein many variations are tried in a single batch. While this reduces the number of iterations, each iteration becomes more tedious, and it can be wasteful of expensive and often toxic materials. Glaze Forge allows the artist to specify what chemical and physical properties they want in the glaze and get the optimal recipe for achieving that result.


25

While this doesn't eliminate the experimental process, it makes for far fewer and more accurate iterations. Like other glaze websites, GlazeForge.com allows artists to store their recipes along with photos and notes. Glaze Forge takes it much further by also understanding what materials a user has available and gives them controls to directly modify every aspect of the glaze within the constraints that they provide. We aim to be helpful to people who are just dipping their toes into glazing by offering wizards that walk you through the process and make good assumptions for expert settings. For expert users, we offer the “power console,” which provides direct control over every aspect of the glaze. As one user put it, “Your program has reenergized me in testing new glazes. I feel like I have my hands on useful dials, and I’m not just shooting in the dark.” Once glazes are formulated (or adjusted), we also offer views for easily and accurately comparing different glazes to understand what's changed. Here’s a typical user scenario: An artist sees a photo of a glaze that they really like, and they try it out by mixing a test batch which is applied on their clay. This recipe will often exhibit one of many potential flaws, including difficulty applying to the clay, cracking after firing or requiring an unavailable ingredient. In this case, the artist can load the recipe into Glaze Forge and adjust the problematic property while keeping the other properties as close to the desired recipe as possible. Are the color/texture possibilities endless when it comes to creating glazes?

Yes and no. Glazes are basically glass that is applied in a powdered form to the unfired clay. This powder melts into a silica glass during the firing. The temperatures (>1200C) and atmosphere (oxidation/reduction) of the firing places limits on colors and effects that can be achieved. Some elements will become volatile and burn off during the firing. Some colors require toxic chemistry to achieve. Glaze Forge plays a key role in helping the artist to push the limits of the chemistry to achieve a wider range of colors while still producing safe, functional pottery. For example, old glaze recipes frequently relied on lead to achieve certain colors, but we’ve since learned not to poison our customers.

Developing a specific glaze is one thing; repeating the process with the same result is another. Gabriel Takacs ’05 and Andrea Wolf SCR ’05 developed a glaze recipe tool to help ceramicists get the perfect result every time.

Describe a time that you hoped for one result but ended up with another. If it was an improvement, could you recreate it?

One thing that I learned from HMC was to take fastidious notes during experimentation. One of our biggest fears is to discover something but not have written down what we did. Even so, ceramics is a fickle process wherein the exact chemistry of the mined materials are not often known (and can vary slightly from batch to batch) and the firing process has a large effect on the outcome. Some effects, such as opalescence, are notoriously difficult to repeatedly reproduce. In fact, the catalyst for Glaze Forge was just such a fickle glaze experiment. We had been playing with modifying a recipe by adding some new ingredients when one of the tests came out as a spectacular result that resembled the waters of a Caribbean beach. Despite detailed notes, we could not reproduce the result. The process of tweaking the glaze chemistry to reproduce this glaze is when we were pushed to the limit of our patience with existing software and felt there needed to be a better solution. After literal years of fiddling around with this recipe, we've concluded that the reason the original came out the way that it did is that it wasn't fully mixed before application.

We've also had a few other pleasant (and repeatable) surprises while experimenting. For example, we have found a glaze that produces a subtle range of pastel color that should not intuitively be the result of the chemicals in the glaze. We overlooked the result at the time, but years later noticed it in our test archives. When we looked up what it was in our notebook, we thought that we must have made a mistake. After remixing the glaze from our notes, we were able to reproduce the result. This is a testament to good note taking and archiving. Who uses Glaze Forge?

Our current users are ceramic artists and educators who have access to glaze-mixing supplies. Some of our customers have signed up to help them fix a single problematic glaze, while others are using it as their primary glaze database. We have a lot of interest from people who want help with custom glazes, but don’t have the space or desire to set up a glaze lab. We’re actively working to expand our offerings to address this set of people.

AABOG Spotlight Recognition Award The HMC Alumni Association selects inspirational alumni whose contributions embody the College’s visionary themes of innovation, leadership and impact through global influence and contributions to society. Joaquin Andres “Andy” Hoffer ’70 (physics) A 2020 HMC Outstanding Alumni Award winner, Hoffer developed Lungpacer, a better way to restore independent breathing that improved upon techniques invented almost 100 years ago. One of his most significant societal impacts came in 2020 when, facing sudden surges in patients requiring intensive care, the FDA authorized emergency use of the Lungpacer RESCUE system to help free COVID-19 survivors from long-term ventilator dependence. For his PhD (biophysics, 1975, Johns Hopkins) Hoffer developed implantable nerve recording electrodes that he subsequently used for postdoctoral research in Alberta, as staff fellow at the NIH and as a Heritage Scholar in Calgary. In 1991, he became full professor at Simon Fraser University, British Columbia, where he continues full-time. His research has led to new clinical applications for controlling prosthetic limbs and for reanimating paralyzed limbs, innovations for which Hoffer and his team were awarded 22 patents. In 1997, Hoffer founded Neurostream Technologies to develop Neurostep,

a fully implanted pacemaker-like device for hemiplegia, and served as chief scientific officer until the company was acquired in 2004. He then co-founded Bionic Power Inc., a company that develops biomechanical energy harvesters and powered exoskeletons to augment human performance and to improve the gait of children with cerebral palsy. In 2007, motivated by his mother’s tragic failure to wean from mechanical ventilation while in intensive care following pneumonia, he conceived a new therapy to restore independent breathing using a temporary transvascular stimulation catheter to activate the diaphragm muscle. He founded Lungpacer Medical Inc. in 2009 and served as the company’s chief scientific officer through 2016. To date, Lungpacer has raised over $80 million in private funding, received a dozen industry awards, has been granted 93 patents (of which Hoffer is the sole inventor in 31 and a co-inventor in another 44) and carried out pilot clinical trials in Paraguay, Europe and the U.S. With support from the FDA’s Expedited Access Pathway, a pivotal trial is underway in over 40 U.S. hospitals. Since 2017, Hoffer has redirected his research efforts to developing innovative, non-invasive methods to help golfers with tremors or focal dystonia to better control precise movements required for putting and chipping.

Register now to celebrate in-person during the rescheduled Alumni Weekend, Friday through Sunday, Oct. 21–23. Reunion celebrations will be held for class years ending in 2 and 7, but all alumni are welcome to join in any part of the weekend.

bruce argall ’68 has been a rockhound since he was first introduced to the concept as a teenager. Living in La Puente, California, he belonged to a Boy Scout troop led by a man with a keen interest in geology and rockhounding: hunting for various minerals and gems native to a geographic location. The troop leader and his son took Bruce along on expeditions to collection sites and mine dumps in California, and they eventually introduced him to lapidary; specifically, the craft of cabochon cutting, in which one turns a natural stone into a smooth convex shape. During his time at Harvey Mudd College, Bruce says his rock-related hobbies mostly took a backseat to college life. “Everyone was the top of their class, and I had to learn to fit in,” he says. “Studies, competitive swimming, water polo and the pursuit of girlfriends pretty well filled my time. However, my higher-level engineering courses and Engineering Clinic work focused on materials.” A lot has happened since his college days, namely a 43-year career at Westinghouse, first as nuclear materials engineer and then as a marketing engineer for the nuclear services division. But in retirement, Bruce has dug back into his craft, expanded his skillset and, recently, has created a gem design inspired by the College. “Gem cutting is more of a craft than an art form. Stone design and presentation are artistic,” says Bruce, who earned a lapidary Master’s certificate from the United States Faceting Guild, the nation’s governing body for the art of stone faceting. Each year, the guild holds a cutting competition to determine

Class of 1992 30th Reunion in California Co-written by Jack I. Houng, Ted Sjodin, Jim Patterson, Dave Nakayama

Despite the cancellation of the 30th reunion of class of 1992, we were able to gather during this period of pandemic, war and huge inflation in small groups connected by emails and messaging. It’s interesting that this was the class that first brought the world’s first free email in late 1990s and, we were able to use that archaic technology to pull together almost 1/4 of the class members including people as far east as Taiwan in East Asia and as far west as Boston, stretching over 12000 km across the globe. We are looking forward to returning to campus in 2027 for our 35th reunion.

A group of North Dorm alumni gathered at the house of James Rudd and Jennifer Herstein in Pasadena. Activities included a morning run to Donut Man, reminiscing over yearbooks and the original facebook and general catching up. Pictured: Justin Stege, Ann Boriack-Sjodin, Barbara Simmons, Elan Katra Scripps, Katherine Schwind, Dan Crevier, Ted Sjodin, Jim Suggs, James Hardwick ’91, James Rudd, Jennifer Herstein, Becky Karlmann ’92/’93.

Many thanks to our then-Physics Chair John Townsend for his generous time and sharing anecdotes throughout his life. While he was concerned about the political stability in East Asia, Jack reassured him that the Taiwan strait isn’t a river one just walks across and that concerns of degradation of education are more dire. We also discussed issues of incumbent theories and the tremendous burden of proof of new findings. John remarked at the end of the three hours that this was the best reunion he ever had.

In Memoriam Founding Class member Ralph Carpenter ’61

(engineering) died in April. After graduating from HMC, Ralph worked one year instrumenting destructive tests of hardware used in the space program at Wiley Labs in Norco, California, and another year doing analog computer simulations of air-to-air missiles at General Dynamics. During a two-year volunteer assignment for the LDS Church in Hong Kong, he learned Cantonese and taught refugees from China. For Lockheed Aircraft, he worked on simulations of the proposed supersonic transport on their analog computer. He later worked for Control Data Corporation on their CDC 6600, then the fastest supercomputer in the world. He helped advance computerized structural analysis and design that used the full power of the supercomputer and resulted in safer buildings, significant savings on steel and concrete and improved building codes. He left CDC to work for Mechanics Research and later became an adjunct instructor at Portland Community College. He is survived by his wife, Vivian, whom he met during his volunteer work in Hong Kong, five children and six grandchildren. Paul Vitta ’66 (physics)

passed away Feb 4. He received his PhD in nuclear physics from Emory University and taught physics at the University of Dar es Salaam in Tanzania for 11 years, during which time he served as chair of the physics department, dean of the science faculty and chief academic officer. He worked for the African Regional Center for Technology in Senegal, then moved to the International Development Research Center in Canada. Before he retired, he was Director of UNESCO’s Regional Office for Science and Technology in Africa.

PHILANTHROPY

Mission: Harmony Jim Campbell ’98 shares his planned giving journey. With the benefit of hindsight, Jim Campbell ’98 has come to see how his time at Harvey Mudd College positively influenced and broadened his worldview. As his career has progressed, he’s witnessed the ideals of the HMC mission statement come to fruition in ways he hadn’t imagined. Now, he sees his support of the College as an extension of that mission. Campbell has more than 20 years of experience developing and evaluating navigation and remote sensing systems with Raytheon Technologies and the Boeing Company. He is a systems engineer at Raytheon Intelligence and Space, and he’s a consultant with USC, performing research for the NASA Cyclone Global Navigation Satellite System, a continuation of his PhD studies. In addition, Campbell volunteers with the IEEE Geoscience and Remote Sensing Society to share his expertise and enthusiasm for science. Were you always interested in the natural world? I grew up in the Puget Sound area of Washington State, mostly Federal Way. I had a modest upbringing; two brothers and a sister. My father was a pastor of a small church and always had a great passion for serving and helping others. He graduated from Harvey Mudd in 1968 with a physics degree. Incidentally, my sister also graduated from Mudd, but later in 2007 with an engineering degree, and she married a Mudder, too. My father often spoke of Harvey Mudd and its challenging curriculum. I always had a natural interest in math and physics, and my father tutored me from an early age. I was doing calculus by 12. I also studied piano for many years. When I was looking at colleges, I had to decide whether to pursue piano or math and sciences. I wasn’t sure what I wanted as a specific career, but realized I didn’t have enough interest in piano, and I never got tired of math and science.

Why HMC? My decision to attend Harvey Mudd was based mostly on its reputation for rigorous academics. I wanted a top-notch school. The low student-to-faculty ratio and the option to sample classes from the other Claremont colleges were also attractive. Mudd was also very generous with providing financial aid. Back then, the College had a program of pairing up donors with students receiving financial aid; I met regularly with my donor couple and really got to know them. They made a big impression. Why was that? The donors, Max and Hilda, weren’t even Mudders themselves. They lived in Claremont and had met Founding President Joseph Platt one day. They were so impressed with Platt’s humanist values that they made regular financial contributions so students like me could get an education. That was so foreign to me: to give without faith-based motives. Their generosity was genuine. And inspiring. Up until that time, all my ideals came from my upbringing in the church. My time at Harvey Mudd instilled scientific principles which eventually led me to reinterpret the world around me in more rational ways. I realized that I have a natural aptitude for the sciences and that there is a demand for these skills and services. By being an engineer, I could find meaning and a place in society.

Sometime after graduating from Harvey Mudd, I received a call from a Mudd student asking for support for the annual fund drive. It made me smile. When I was an undergraduate, I had seasonal work in the alumni office, calling up alumni asking for contributions; I was amazed at their financial responses. Of course, since I had been on the other end of the call many times, I had to make a donation, something I have continued to do ever since. How did your planned giving to Harvey Mudd come about? Like many other American workers today, much of my personal wealth is invested within qualified retirement plans. When I realized that colleges and universities could be designated as beneficiaries of these plans, I thought, “Here is a way I can make a bigger impact for Harvey Mudd.” It made sense to me since Mudd was so instrumental in shaping my early life and thinking. It all comes back to the Harvey Mudd mission statement with its emphasis on the humanities, social sciences and the arts in addition to understanding the impact of scientific work on society. When I was at Mudd as a student, that seemed secondary, but only later have I come to fully appreciate its intrinsic value. It’s a statement that is so in harmony with my personal values today.

What about life after HMC? I took a job as a systems engineer in the defense industry, but I wanted to broaden my professional engineering experience, so I enrolled in night courses at Cal Poly Pomona for my master’s in applied mathematics, which I received in 2006. In 2014, I decided to pursue a PhD at USC.
