Contemplation and Collaboration when john harrell was an engineering student at Harvey Mudd College in the late 1960s, he would often roam the nearby California Botanic Garden to clear his head. Today, students don’t have to leave campus to find a quiet place to read, think and reflect, thanks in part to Harrell and other members of the Class of 1969. For their 50th reunion gift, the class has joined forces on a fundraising drive to create and maintain a new garden area and to establish an endowed fund to support students and faculty engaged with HMC summer research projects. The Contemplation Garden is located south of East Dorm in a shaded, quiet corner of campus, far from the flurry of the main thoroughfare. It features a fountain, three Italian-made wooden benches, lighting and a commemorative plaque mounted on a large boulder that reads: “Let your time in this garden awaken a gentle peace, a commitment to truth and empathy for others. May it inspire profound insight and innovation.” The Class of ’69 Summer Research Fund will further enhance the development of “insight and innovation” by supporting faculty and students in their research endeavors. Class members are rallying behind the endowed fund because they believe that supporting research is crucial to developing a national reputation among faculty members and the College while providing experiential learning for students. During 2020, gifts toward the Class of ’69 Summer Research Fund supported Christopher Paniagua ’21, who worked with engineering professor and fluid mechanics expert Leah Mendelson to study the waterexit strategy of the archer fish and the engineering applications of this behavior. The fund will support one or more students each summer as it grows into perpetuity.
Members of the Reunion Committee who spearheaded the fundraising drive, with collaboration from College staff, generated gifts and pledges of nearly $250,000: $75,000 for the garden and $175,000 for the summer research fund. Committee members discovered that both elements—an endowed fund for a specific purpose (summer research) and the tangibility of a garden—inspired significant interest. Boosting this effort was a participation challenge—committee members agreed to double their pledges if 60 percent of class members gave toward either effort—that helped the Class of ’69 achieve beyond expectations and create momentum for building the endowment. With staff members in advancement and facilities and maintenance providing support and encouragement throughout the initiative, fundraising to establish the garden and research fund was a positive and rewarding endeavor that the Class of ’69 hopes other reunion classes will emulate.

PRESIDENT’S MESSAGE The Next Phase as we move into the summer months and welcome student researchers back to campus for some in-person activities in labs and shops, we are thrilled with the progress we are seeing on many fronts. We’re busy planning for a return to campus this fall, and work is underway to move our computer science faculty into their new offices and classrooms in the Scott A. McGregor Computer Science Center. Our student stewards are busy working with Professor Jeff Groves to get the new makerspace ready for our community to enjoy this fall. At the May meeting of the Harvey Mudd College Board of Trustees, we celebrated the many accomplishments of the Class of 2021. While the class decided to postpone an in-person Commencement ceremony until spring 2022, pending approval from the L.A. County Department of Public Health, we were happy to celebrate with them and wish them well as they begin the next phase of their lives as alumni of the College. Also, during the board meetings in May, I officially informed the board of my decision not to seek an extension of my current contract as president of the College. This means that I will leave the presidency at the end of June 2023 when my current term ends. I want you all to know that serving as president of Harvey Mudd College is now—and has been—the greatest honor of my academic career, and I am incredibly proud and grateful for everything we have accomplished together. While we have all grown pretty weary of them, we’re getting very good at online events, as our community members can attest. Nearly 300 parents and guests attended some portion of our Family February programming. More than 300 alumni met over the airwaves during Alumni April to celebrate their reunions in an incredible show of unity and solidarity (see page 30). I’m so proud of our alumni. They are problem solvers making incredible contributions to our nation and the world, including on earth (sustainability efforts, pages 24, 26 and 35; technology, page 33) and beyond (Mars, page 20). Our faculty moved so adeptly to online teaching, and many have managed to do research and earn prestigious grants and
awards (page 8). They and our staff pivoted gracefully to ensure students remained supported. Our students have persevered and have found creative ways to collaborate, including our first-year class who managed to form a community despite never having been together on campus. We know that our incoming students, chosen from a record number of applications, will bring their own talents and energy to campus. This class will be the College’s most diverse with 22.6% Hispanic/Latinx students, 8.1% Black students and 13.7% multiracial students. It’s been a difficult year and a half with so much struggle and change. I’m so thankful for all community members who’ve demonstrated their ongoing commitment to Harvey Mudd College and for everyone’s extraordinary work in providing a safe work and learning environment. Thank you all for your friendship, advice, hard work and dedication over the last 15 years. Harvey Mudd is a truly unique place, with a tremendously supportive community. I plan to continue serving as president for the next two academic years with all of the focus and energy that I brought with me in 2006. In the coming months, community members will have many opportunities to have important conversations about who should lead the College in the next phase of its development so as to best position the next president of Harvey Mudd College.

Sustainable Steps The College continues to reduce its carbon footprint Solar carport
Three solar arrays were completed in April and are now tied in to The Claremont Colleges system. Two of the arrays are located near the southern half of the Drinkward Residence Hall parking lot and the third is sited near the eastern edge of Linde Field. Approved by the board in September 2019, the arrays will supply roughly 8% to 10% of the College’s power needs. “It’s a typical power purchase agreement partnership with First American Education
E.V. Charging stations
Finance,” says Rick Vanzini, HMC’s senior director of capital projects. “There’s no upfront cost to Harvey Mudd for the 25-year agreement. The system produces energy, they own it and we pay a fee to First American Energy which pays all the upfront costs.” With the College’s first solar project in place, students are providing input for the location of another carport or rooftop structure.
Gifts from Tom Bleakney ’69 and Marcus Witte P18 P21 have allowed the College to add two new dual-port charging stations in the Parsons Building parking lot. Along with another dual-port station installed in 2015—also funded by Bleakney—there are now six charging spots available to the HMC community. Bleakney and Witte have provided a 1:1 match to raise $30,000—toward a goal of approximately $60,000—to cover recent installation costs and to fund additional ChargePoint stations at the solar carports.

Magazine CASE Study You may have noticed the magazine has shrunk a little. Comments from magazine readership surveys about the size of the magazine (it was previously 10.5 x 11 inches) led us to resize it to a more standard format beginning with the fall/winter 2020 issue. During summer 2020, the College participated in its third readership survey administered by the Council for Advancement and Support of Education (CASE). These surveys help us evaluate how readers view this magazine and allow us to compare results to those of other higher ed institutions. Thanks to those who participated for providing valuable information on reader preferences. Results show the magazine continues to be well-read with respondents spending at least 30 minutes reading some to all of it (85%). The print version is still overwhelmingly preferred (62%), though having both print and online is desired by 24%. Respondents’ article suggestions include student-driven content and culture, books by alumni, diversity and inclusion at Mudd, side-gig workers, student research, social responsibility and activism, HMC curriculum and more class notes.

Professor Emeritus of Engineering Jim Monson died Jan. 1, 2021 surrounded by his three children and Julie, his wife of 65 years. He led a full life of teaching, research, caring for his family and volunteering in his community. He worked at Bell Telephone Labs and Hewlett Packard then began his academic career at Harvey Mudd College in 1961. Because the College had begun enrolling students only a few years earlier, Monson and his few colleagues created an innovative curriculum in engineering, with components of the humanities. He also helped establish and develop Engineering Clinic and began working with colleagues in industry on the challenges of the evolving technology in magnetic recording. He and his student researchers collaborated with engineers from around the world. He published over 30 articles and book chapters and is co-author, with A.S. Hoagland, of Digital Magnetic Recording (second edition). Monson was chair of the engineering department from 1979 to 1983 and faculty chair (the College’s second) from 1976 to 1979. As chair of the Computer Science Group from 1973 to 1975, he helped recruit CS faculty and directed the planning of the CS curriculum. He also served as director of the College’s Freshman Division. He remained at Harvey Mudd for 35 years and loved it. The HMC Alumni Association named Monson an Honorary Alumnus in 1997 and, the same year, he was named a Fellow of the Institute of Electrical and Electronics Engineers. Members of the Class of 1963 have established the James Monson Endowed Scholarship and have secured $50,000 in matching gift funds. The scholarship will provide aid to HMC students with financial need while also honoring Monson’s legacy. For information, contact Hieu Nguyen, VP for advancement, at email@example.com.

Modern Classical Mechanics, a textbook co-authored by Vatche Sahakian and Thomas Helliwell, was published by Cambridge University Press in January. The forward-looking physics text shows the deep connections between classical (Lagrangian) mechanics and modern research in theoretical physics. Helliwell and Sahakian present classical mechanics as a thriving and contemporary field with strong connections to cutting-edge research topics in physics. The textbook, published in digital format in November 2020, was used in Brian Shuve’s fall 2020 Theoretical Mechanics course. The Research Corporation for Science Advancement named Brian Shuve as a 2021 Cottrell Scholar, an award for outstanding teacher-scholars in chemistry, physics and astronomy. Cottrell Scholars are educators and researchers focused on innovative teaching in the sciences. Shuve will use the $100,000 grant to support two projects: “Matter-Antimatter Asymmetry from Dark Matter Freeze-In,” which seeks to address the nature of “dark matter” and “matter-antimatter” within a common framework, and a physics education project inspired by his four years teaching theoretical physics. The latter project will result in interactive applets that Shuve will use to help students integrate the abstraction of the material into their knowledge base.
patterns—a beautiful example of a complex system. Complex systems are applicable to many real-world applications, like cells, human brains, voting, disease spread, climate and social networks (my interest). What was the impetus for the AMS course?
A Simple Lesson on Complex Social Systems communicating mathematics in a way that is exciting, relevant and inclusive is a goal of Heather Zinn Brooks, assistant professor of mathematics. As an applied mathematician working in complex and nonlinear systems, she studies a variety of social and biological systems with mathematical models. In January, she co-organized the online, well-attended international 2021 AMS Short Course Mathematical and Computational Methods for Complex Social Systems, a gathering for those seeking to gain a better understanding of how interacting parts in a system—like Twitter accounts, pedestrians or voters—respond to each other and to their environment and how this impacts society.
I co-organized the workshop with three friends and collaborators: Alexandria Volkening, a postdoc at Northwestern University, Mason Porter, a professor at UCLA, and Michelle Feng, a postdoc at Caltech. It came out of a 2018 conference session, “The Dynamics of Democracy,” that Alexandria and I organized during which speakers discussed gerrymandering, election forecasting and opinion dynamics. We realized there was this real hunger among math people to learn more about how to use math to study social systems and what work was out there to study social systems with math. So, we hatched a plan to keep building up this community within mathematics. How does your specialty fit into this community?
I do math modeling of complex systems. I’ve recently been really interested in mathematical models of opinion dynamics. I bring together tools from dynamical systems—basically studying systems that change in time—with ideas from networks. The network piece is really interesting when you’re thinking about mathematical modeling of opinion dynamics because networks give us a way to think about connections between people or social entities. The focus of my talk for the short course was a whirlwind tour of the mathematical techniques that mathematicians who study networks use and to highlight what’s special about social networks. When we think about networks, we think about these agents or particles in a system being connected in a very specific way; we actually model the connections. You can study a lot of the features of the structures of networks, whether they’re networks that are from a social system or not. For example?
How do you define complex social systems?
Technically, a complex system is one that consists of many interacting particles or agents, for example, a flock of birds. Each individual bird has its own behavior, its own set of rules that it’s following, but if you zoom out, then the flock moves together and creates HARVEY MUDD COLLEGE MAGAZINE
I think Twitter is a wonderful example to talk about the notion of degree of the network. Degree is a way to measure the importance of nodes (the individuals in our network). On Twitter, that’s accounts. We could use something like degree to try to quantify the importance of an account on Twitter; perhaps
importance is somehow proportional or relative to how many followers you have. For example, Dionne Warwick’s Twitter account has many Twitter followers. You could then compare that to something like the Twitter account of Harvey Mudd College, which has many followers but orders of magnitude less than Dionne, and then compare that to my Twitter account, which is orders of magnitude less than that. Something that is special about social networks is that it’s very common to have a lot of nodes (accounts) that have very few followers. The distribution would show a steep drop off, but then a really long “tail,” with just a very few accounts that have a huge number of followers in networks. We call this a heavytailed distribution, one signature feature of social networks. In your Harvey Mudd classes, how are you linking course content with real-world applications and current research?
I’m excited to do this in the fall when I teach a class called Mathematics of Democracy. We’ll explore how mathematics illuminates, informs and impacts the democratic system in the U.S. It will include reading and discussion of state-of-the-art mathematical research on topics surrounding the democratic system: apportionment, voting theory, election forecasting, judicial system, social movements. I’m hoping to get some great guest speakers. This topic is such an exciting area of applied math research and the cool thing is students can see what’s happening right now. In mathematics, a lot of what we do in the undergrad curriculum is very old; 100 years old feels new in mathematics. This is an area of mathematics where students can read and engage with the what’s coming out this year. Any other real-world lessons you like to share with your students?
I have had a longstanding interest in politics, but it took a long time before I realized that I could combine politics with mathematics. You can learn so much from talking to people outside your area and sometimes you find really surprising connections. This is part of the reason it’s great to be at The Claremont Colleges. We have this whole community that’s really passionate about a wide range of things; it’s the perfect place to get out of your bubble and follow what’s interesting to you.

Projects Support Black Communities Written by Mariana Duran
hosted through zoom and a discord server, Hack for Black Lives tasked 7C participants with developing projects to support Black communities and the Black Lives Matter movement, coded or otherwise. What arose was an array of work: apps, legislation, data mapping, event planning. The hackathon, hosted the weekend of Feb. 19, was created and organized by a group of Harvey Mudd students and alumni inspired by the Black Lives Matter movement. Natasha Crepeau ’21, Kira Favakeh ’20, Ben Hinthorne ’21 and Camille Simon ’21 hoped to encourage students to contribute their individual, technical skill sets to the movement, whatever they may be. The group spent fall semester 2020 meeting with potential Hack for Black Lives sponsors, creating a website, planning the event and promoting it across the 7Cs. HMC supported the event as did the Office of Black Student Affairs and the Hive, which provided workshops and mentors for the participants. From rising first-years to PhD candidates, about 170 students and alumni signed up for the hackathon. Many had never tried coding, much less participated in a hackathon before. The project’s programming and categories— legislation and political action, Black history and education, community organizing, algorithmic bias reduction, and promotion of Black artists and voices—were crafted to inspire projects that not only aligned with the mission of the Black Lives Matter movement but also worked holistically toward anti-racism. On Friday evening, Justin P. Christian P25, founder and CEO of BCforward, inaugurated
Hack for Black Lives with a keynote speech that encouraged students to continue fighting for racial equity. Later that night, participants attended workshops to provide them with skills related to community impact, design and social innovation. The 48-hour hackathon wasn’t enough time to complete most projects, but that was OK. Hinthorne said, “The point of a hackathon isn’t to create something polished—it’s to try something out and build something, and however far you get, you’ll be celebrated.” Organizers hope that Hack for Black Lives inspires similar hackathons elsewhere and that it will become an annual event at the 7Cs. “I hope that there’s enough interest from the people who participated in it for something like this to happen again,” Savanna Beans ’22 said. “I think that people can benefit from thinking about problems that may not necessarily affect them.”
The third annual DSA Carnival, co-sponsored by the ASHMC Sustainability Committee, featured the debut of EcoBud, an app created as part of the CS Summer Start-up program. The progressive web app aims to construct a more efficient and community-based approach toward developing sustainable practices. Participants in the residence hall-based contest competed for prizes by logging their sustainable actions, like turning off unnecessary lights, washing clothes with cold water, composting food scraps and being vegetarian for the day. Top finishers were Case, West and Drinkward. Creators hope to use the app for future campus sustainability initiatives, helping more people become environmentally conscious “in a new and fun way.”

Fellows receive a $36,000 stipend for 12 months of travel and college loan assistance. He plans to defer his Watson Fellowship for one year to enter a PhD program at Georgia Tech, where he will study operations research.
“ I will be shadowing community physicians and interviewing community members to gain insight into how different nations have generated novel solutions to healthcare inequity. I believe access to healthcare is a prerequisite for a just society. I wonder how we can say that we live in a society predicated upon equality if I can expect to have a life that is 20% longer than my neighbor simply because of my ability to access healthcare.” –ABEL SAPIRSTEIN ’21

CRA Outstanding Undergraduate Researcher
The 2021 recipients of the most prestigious national award for undergraduate STEM researchers describe what they’re working on.
Joint computer science and mathematics major Lindsay Popowski ’21 received the Computing Research Association’s 2021 Outstanding Undergraduate Researcher Award. She’s worked on several research projects with professors at HMC and at Carnegie Mellon University since her first year, studying CS education, developing new dynamic scheduling algorithms and creating vector representations of app screens. She looks forward to earning a PhD in human-computer interaction. The CRA also recognized a number of finalists, including joint computer science and mathematics major Abtin Molavi ’21, who plans to pursue a PhD in computer science.
Tonatiuh Gonzalez ’22, a math and computational biology major, is doing research with Eliot Bush, who studies microbial genome evolution. “Our research is about reconstructing the evolutionary history of bacteria and identifying events that may have given bacteria environmental or antibacterial resistance or increased virulence.” Jacob Kelber ’23, a chemistry major, worked during summer 2020 with Katherine Van Heuvelen to develop new, environmentally friendly catalysts for important reactions. “The goal of my research was to computationally screen a catalyst for the detoxification of potentially carcinogenic industrial pollutants perchloroethylene and trichloroethylene,” says Kelber, who also worked with chemistry professors Hal Van Ryswyk (HMC) and Nathan C. Gianneschi (Northwestern). “I was able to successfully find an iron-based catalyst and model its reaction with PCE and TCE.” Hanna Porter ’22, a chemistry major, is working in both Hal Van Ryswyk’s chemistry lab and Tom Donelly’s physics research group. “I have been involved in research involving quantum dot size determination via pulsed-field gradient NMR in Professor Van Ryswyk’s lab and developing an RF-plasma reactor for gas-phase graphene synthesis in Professor Donnelly’s lab.”
Shion Andrew ’21 is one of the exceptional American students selected to pursue graduate studies at Churchill College at the University of Cambridge in England. A physics major, she plans to conduct astrophysical research at Cambridge during the 2021–2022 academic year. Andrew will research fundamental questions about the evolution of the universe through mathematical modeling and computer science. She is interested in the versatility of the information extracted from large datasets and plans to explore this research interest further by collaborating with astrophysicists who explore the parameter space of these surveys.
Anna Soper ’22, physics and math major and a member of Lori Bassman’s research team, is studying metal alloys and working on computationally simulating their compositions and structures. “My current research is in the field of computational materials science, where I am investigating the chemical and structural mechanisms by which the brittle sigma phase in a novel stainless steel substitute is destabilized by the addition of aluminum, producing a useful, ductile alloy.”
MY MUDD LIFE
All Together Ooky artist and mathematician fletcher nickerson ’22 was part of the 40-member 5C team that transitioned the live theater production of The Addams Family Musical to a socially distanced, 2.5-hour movie. CMC News describes their effort: “The actors set up 9-by-13-foot green screens, lighting and cameras in their homes, and the director and choreographers could simultaneously see what the camera was recording via Zoom. With editing software, and many re-shoots, they brought actors together in their scenes with large-scale, hand-drawn backgrounds (commissioned from Fletcher Nickerson at Harvey Mudd College) and animation.” We asked Nickerson to tell us more.
“House exterior, gate open”
How did you become involved with the play?
I originally joined the project as a set designer last spring semester, when we were anticipating doing an in-person production. I was expecting to design and help construct the set. As we shifted to working on a virtual production, I stayed on as a set designer, but had to adapt what form that design was going to take. How many backgrounds did you do?
By my count I’ve completed about 32 backgrounds, though there were a number of others that stayed as drafts or that we ended up not needing.
“ I was expecting to design and help construct the set. As we shifted to working on a virtual production, I stayed on as a set designer, but had to adapt what form that design was going to take. ” FLETCHER NICKERSON ’22
How long have you been doing art, and what are some other works you’ve created?
I started learning about set design and construction in high school and have taken a couple of theatrical design/ installation art/ theater-adjacent courses at Pomona. Before the pandemic, I did set and makeup design for Madeleine Kerr’s production of Isaac’s Eye at Mudd and makeup design for Macbeth at Pomona. I’ve also done a bunch of digital art, including some sketches based on Seifert Surfaces (knot theory) and a couple comics inspired by the ant lab I’m in. Any other art projects planned?
Not at the moment. I just learned to animate, so I might do some experimenting at that. I’m also doing bee research this summer (Prof. Matina Donaldson-Matasci), so I’ll probably end up drawing some comics about the unexpected things our colonies do. What is your STEM interest?
I really like both knot theory and social insect behavior; hoping to find some surprising way to connect the two.

HUMANS OF MUDD Interviews by Michelle Lum
Like its distant photoblog cousin in New York, Humans of Mudd is about getting to know people in your community. The Mudd version was started in early 2020 by Michelle Lum ’23, a journalist (The Student Life, Muddraker); computer science major; baking-climbing-tennis-book-carbs enthusiast; and collector of blue things. She’s conducted numerous interviews with a goal of sparking conversations and helping bring the HMC community closer. “I feel like coronavirus is forcing us to think of ourselves more as a society and think of others more,” Lum said in a May 2020 interview with TSL. “Hopefully Humans of Mudd will continue to be something nice for our community as well.”

Rin Ha ’24
Rin Ha ’24 I was very lucky to have found friends. They’re really what made the fall semester bearable and actually somewhat fun, despite the circumstances. In the beginning of the school year, someone created a frosh study groups sheet that had different tabs for different classes. You could put a Zoom link and say, ‘Hey, we’re going to be working on this homework problem at this time. If you want to join, just put your name there, and hop in.’ For the first Spec Rel homework, eight or nine of us joined, and we took forever on the very first problem. We all even hopped into Saeta’s office hours. He gave us a hint, and we were like, ‘Oh we got it,’ and then we went back and we were like, ‘Wait, we actually don’t get it.’ So, because we couldn’t solve that first problem, we made a Discord chat to figure it out. After more struggling, we were able to finally figure it out. And since we had a group chat, people kept talking, and we decided to continue doing physics together. So, on the day the Spec Rel homework came out, we would all meet on a Zoom and pull through the homework together. It was really fun collaborating, even over Zoom. I can’t imagine how much better it is in person. I don’t feel like part of the whole Mudd community as much as I would have if we were on campus. But I feel like I have a small
community in my group of friends. We just enjoy spending time together. And, I mean, there’s no better way to bond than over struggling to do Spec Rel homework. We have a Zoom link we usually go to. We play Among Us or Jackbox or Skribbl.io. Every Friday—because there’s the Great British Bake Off going on right now—we watch it together through Netflix Party. When it’s someone’s birthday, we all go on Zoom and have some crazy virtual background on to make fun of them. We awkwardly sing ‘Happy Birthday’— totally not in sync—and we usually coordinate to get them a gift. My friend’s birthday was a couple days ago, and we got him a yodeling pickle. My friends make me feel like I am still in the Mudd community, but I don’t feel like that’s the complete Mudd community. We’re kind of in a frosh bubble. So, I definitely can’t wait for when I actually get to fully experience the Mudd community. In terms of returning to campus, I’m just excited to meet everyone at Mudd. I’m excited to talk to upperclassmen and to hear what their experiences were like. I think it’ll just be fun to meet new people, because from what I’ve seen so far, even in breakout rooms, everyone’s been really nice and helpful, and I think it’d be really great to get to know a lot more people once I’m at Mudd.”
Kayleah Tsai ’24 and Lilly Lee ’24 Kayleah Tsai ’24
Tsai: My dad is a Mudd alum, and I always looked at his yearbooks when I was younger. So, I always thought that going to Mudd would mean getting a yearbook. I was a little disappointed when I found out that Mudd recently stopped having yearbooks. But I heard that someone was restarting the club. So, I sent an email out to Spectrum and was like, ‘Hi, I wanted to join the yearbook club,’ not thinking that I was going to be given the entire club. I just thought I was going to join as a frosh, but they gave me the club. So, that was a little scary. I’m thankful for Lilly because I could not have done that by myself.” Lee: “I met Kayleah at one of the Mudd
Lilly Lee ’24
meetups in Claremont. Basically, I was like, ‘Hey, I don’t have a ride. Is anyone available?’ And Kayleah said, ‘If no one else volunteers, I can pick you up.’ Then, she became my Uber driver, unofficially. I decided to join the yearbook club because I saw Kayleah’s email, and I thought, ‘This person is cool, and I’m interested in yearbook as well, so I’ll sign up.’ The club president thing came afterward.” Tsai: “Lilly was so helpful the first meeting.
1996 HMC yearbook: “Speak no physics, see no physics, hear no physics.”
HARVEY MUDD COLLEGE MAGAZINE
She was like, ‘I can do this for you, I can do this for you, I’ll send out this email,’ and I said, ’Lilly, you need to be promoted. You need to be a co-president.’ That’s how we became co-presidents. Our club is mostly frosh. There are a few sophomores that are pretty active.
I think it’s probably because frosh are interested in giving back to the community they just recently joined. But we’re also friends. That makes it better; we can chat about other things, not just the yearbook.” Lee: “I really like the spread I made—the
fashion spread—because I was able to make little side comments in it that I felt like regular yearbooks would say were too casual. But because Mudd is so unique and wild, I don’t feel pressure about putting it in there.” Tsai: “Anything that has Lilly’s writing
is going to be precious because she has the best humor, and she’s so snarky. So, definitely look out for those paragraphs. I think you can tell which ones she wrote. Something I’m looking forward to is Liza’s map showing where everybody is in the world this year. It’ll be cool to see how spread out we are. The theme of the yearbook—Mudders Around the World—is that we’re still a community even though we’re around the world.” Lee: “With student submissions this year,
we get to see another side of students that we wouldn’t normally be able to see. It’s nice to see students submitting what’s personal to them, what’s important to them.” Tsai: “I think it’s also a community effort.
Everyone helps contribute to the yearbook, so everyone gets to have a part in it, and hopefully, that’s a reason to buy it.”
Travis Paddock I’m the custodial services and mailroom manager. I’ve been at Mudd for six years now. I started at the night shift, working custodial, and worked my way up to lead, and then to night supervisor. Now I’m supervising during the day. I’ve had the pleasure, within the past two and a half years, of managing the mailroom. With coronavirus, it’s a whole new world. We’ve got a lot more guidelines to follow: CDC guidelines, L.A. County guidelines. We’re sanitizing, disinfecting areas multiple times a day. We’re cleaning each restroom three times a day. We’ve re-strategized to make sure that we’re providing the safest environment for folks on campus. We’ve added signs to direct the flow of traffic, placing arrows that keep you going a certain way to prevent folks from crossing paths. There are sanitizing stations and wipe stations as far as the eye can see. We’ve got
signs posted clearly at each entry, saying if you’ve got any kind of symptoms, please don’t enter. Each day, we have a safety check-in process, where we acknowledge the fact that we don’t have any symptoms, that we will maintain our CDC protocols of keeping distance throughout the day. When the students come back, we will need to maintain this level of quality. Right now, things are very quiet. However, when everybody’s back, we’re going to try to continue to do this on a large scale—which I have confidence that we will have no problem with. However, it will be a different beast, that’s for sure. It is strange to be on campus without all the students. It’s lonely. We miss everybody. We have enough to do here so we are not bored by any means, but we miss the traffic. We miss the activity; we miss hearing everybody around. It feels good to see all the
faces you’re trying to care for. But we stay diligent. We miss everyone, we look forward to having them back, we know that we’re on the edge of having at least some kind of normalcy —whatever normal is defined as now. We’re looking forward to it. And we’ve just been here practicing the same skills that we’re going to utilize when folks get back. I love it here. When I first started here, I was just totally inspired. I started on the night shift, which is also a different aspect of the College—the things you see at night, the kids that are up studying all night, the professors you run into—it was great. It was inspiring to come here and see all that the kids were accomplishing—stuff written on these walls and boards that I couldn’t figure out if I had a mathematician right next to me. I fell in love right away, and I’ve been here ever since, just enjoying each year. We’re looking forward to having you all back. Can’t wait to see you.”
EYES ON MARS Part hobby, part job, Christopher Pong ’s work on the Mars 2020 Perseverance Rover mission has been an emotional journey Written by Janie Fisher Photos provided by NASA
HARVEY MUDD COLLEGE MAGAZINE
rowing up in Hawaii, Christopher Pong ’08 built robots and rockets for fun and watched meteor showers with his mom and dad. They talked of ancient Hawaiians navigating by the stars. And they imagined other worlds. Now a cruise attitude control engineer on the Mars 2020 Perseverance Rover mission, Pong ’08 finds himself working on spacecraft designed to explore them. Pong joined JPL in 2014 and has been working on Perseverance for the past four and a half years delivering flight software and parameters, performing requirements verification and validation and, among other things, operating the spacecraft during the cruise phase, performing turns and trajectory correction maneuvers. “The spacecraft acts like a gyroscope, so its spin axis will remain pointed in the same direction. But we need to periodically turn the spacecraft to keep the solar arrays pointed to the Sun and the antennas pointed close enough to Earth.” Pong loves his work and clearly hasn’t lost his enthusiasm for space exploration. Or his sense of fun. “There are times when I don’t feel like it’s a job. It’s just a really cool hobby to have.” Among his other hobbies, Pong reads a lot of science fiction. On landing day, he wore a red mask with a small wolf on it—an "Easter egg” for fellow sci-fi fans—from Pierce Brown’s Red Rising series of books, set on Mars hundreds of years in the future. Red Rising fans who watched the landing took notice, looked for him on the JPL website and posted about it on social media, prompting team members to text Pong that “people were looking for him.” It was a light moment during an extremely intense day. The final entry, descent and landing phase of the journey—known as the “Seven Minutes of Terror”—unfolded like a science fiction story, where anything could happen and everything had to go right. It was the last seven minutes of a seven-month journey and it was nerve-racking, to say the least. “I was pretty tired. I didn’t get much sleep the night before. That was balanced with

adrenaline. We really couldn’t do anything to change the outcome of the landing. We could lose the entire mission right then and there. But when I heard ’Touchdown confirmed’ it was just an overwhelming sense of relief and joy.” How did Pong get lucky enough to land a job he loves at JPL? Luck had little to do with it. His years at Harvey Mudd launched him on a path toward NASA. “What probably shaped my trajectory the most was the Clinic Program at Harvey Mudd, where I worked on a project for The Aerospace
Corporation. My mentor was Professor John Molinder, and the project was about finding these small satellites in space that are hard to locate after launch. Because of that, I got an internship at The Aerospace Corporation.” After Mudd, Pong moved on to MIT where he earned a master’s and a doctorate in aeronautics and astronautics. While there, he won a NASA Space Technology Research Fellowship. “It paid for part of my tuition and forced me to do internships at different NASA centers. I spent a few months at Goddard Space

Flight Center and a summer at JPL. That’s how I got to know a lot of the people that I work with today. And it’s how I got a job at JPL.” For his doctoral thesis, Pong worked on a project called ExoplanetSat, later renamed ASTERIA, a small satellite designed to look for new planets around other stars. “We were looking for a partner that would take the project to space, and JPL took it on. ASTERIA moved to JPL at the same time I did, so I was able to keep working on it.” Since then, he’s been on the Perseverance mission whose goals include collecting samples
of rock and soil from Mars to be brought back to Earth for detailed study. “My next project is the proposed Sample Retrieval Lander, which will pick up the samples and shoot them off into orbit around Mars. And it’s a whole international collaboration with the European Space Agency that has its own Earth Return Orbiter, which will pick up the samples and bring them back to Earth.” The samples will help determine if microbial life once existed on Mars. “There’s a scientific reason for just exploring,
following human curiosity,” says Pong. “There are so many scientific questions that could be answered: Was there life? Is there life? And what happened on Mars that made it so different from Earth? And, of course, if you sort of buy into the existential crises that humans might face in the future, then getting humans on multiple planets, or even in multiple solar systems eventually, is important for the survival of the human race.” Spoken like a true science-fiction fan!
How to Cultivate a Career
Geophysicist Betty Johnson ’78 overcame a steep learning curve to become a leader in the field. Written by Kristin Baird Rattini Photo by Jeanine Hill
HARVEY MUDD COLLEGE MAGAZINE
t was spring of betty johnson’s junior year at Harvey Mudd. Interviews with several oil companies hadn’t led to an internship, so the physics major with a geophysics emphasis resigned herself to the idea of once again working retail over the summer. Then, at the last minute, Unocal offered her an internship in the geophysics department working on a statistical project. She accepted despite one major challenge. “At that time, I hadn’t taken any statistics classes,” says Johnson ’78, laughing. “It was a steep learning curve, but I had a fantastic boss who mentored me. I learned about everything the geophysicists were doing. I knew at that moment it was definitely what I wanted to do.’” Johnson’s subsequent 43-year career in the petroleum industry as a geophysicist with Unocal (acquired by Chevron in 2005) has been a testament to the rewards of seizing and creating opportunities that stretch one’s skill set in new and unexpected directions. At every turn, Johnson has leveraged her technical and managerial skills and Harvey Mudd education into innovative and prominent positions in a male-dominated field while staying at the forefront of dramatic changes in how terrain and talent are cultivated. “In my career, I’ve seen an evolution of companies, technology, geophysics and women in the workplace,” she says. Her first position at Unocal, geophysical technician, wasn’t exactly what she had in mind, but it got her foot in the door at corporate headquarters in the Los Angeles area. The workplace “was still a lot like Mad Men,” she says. “Women had to wear dresses and skirts and pantyhose. Most of the women were secretaries. I definitely felt out of place as a female scientist.” While at Harvey Mudd, Johnson had valued the support and collegiality of the Society of Women Engineers (SWE). She recreated that nurturing environment by serving as one of the “founding mothers” of the Association for Women Geoscientists (AWG). “It was instrumental for me because at the time there were few leadership opportunities for women within work,” she says. “I found amazing colleagues through AWG and learned a lot about leadership.” Johnson’s career advanced in tandem with computing technology and the development of geographic information systems.
She distinguished herself by mastering new software as platforms evolved from mainframe to workstations to PCs. “I quickly became an expert, which is a testament to the strength of the Harvey Mudd education,” she says. “I had only a bachelor’s degree, which was unusual in my field. But Harvey Mudd taught me how to learn and solve challenging problems.” Early in her career, Johnson also was tapped for a task force that defined a technical career path within the company. “It was an incredible project, a peek behind the curtain of how people were managed,” she says. That one assignment served as a springboard for several subsequent higher-level management positions. She took on leadership of the Gravity, Electrical and Magnetic Services team, an area that was not her strength in college but provided an exciting learning opportunity in offshore exploration. She oversaw talent management, from recruitment through leadership development, for the 475-member Earth Science Department. Until recently, she managed the dozen or so technically diverse members of the newly created basin framework analysis team, which analyzed potential exploration sites around the world. “I felt like I was in The Big Bang Theory every day,” she says. “It was a joy to learn about each team member’s deep expertise and find ways for these very different disciplines to work together.” These are very different times for the petroleum industry from when Johnson first
started. As science and public sentiment have shifted away from fossil fuels, Chevron has stated its dedication to a lower-carbon future. “As earth scientists, we have a role to play at all points along that spectrum,” Johnson says, “from producing oil and gas in a clean and safe way to looking for alternative sources of energy.” As she contemplates retiring in the next couple years, Johnson has been focusing her attention on the next generation of scientists. While serving on Harvey Mudd’s Alumni Association Board of Governors, she helped lead fundraising efforts for the curricular innovation fund, which has exceeded its $100,000 goal. In her new role at Chevron as subsurface talent manager, she’s engaging employees at all levels in championing new ways of working together in a digitally connected world—lessons learned during the pandemic. “In the span of 40 years, we’ve learned a lot about leading people, how teams work together and how innovation actually happens,” she says. “One of the things we’ve learned this past year is that we have to empathize with what’s going on in people’s lives and how that affects their thinking, their availability and other factors. There’s a shift to a more caring style of leadership. That’s what I saw in SWE and AWG, and it’s exciting to now see this actually be the core of how companies like Chevron foster our own workforce.”
What’s the Future of Phosphorus? Chemist Louis Kuo ’84 explores ways to create more usable phosphorus before it’s gone. Interview by Stephanie L. Graham Photo by Rob Reynolds
ouis kuo ’84, a professor of chemistry at Lewis & Clark College since 1992, was drawn to his research area—phosphorus— because of food. Its presence in food preservatives, animal feed and especially fertilizers, impacts our food supply in profound ways. If not for agricultural herbicides and pesticides, we wouldn’t have such robust crop production, but the carcinogens they contain can damage our brains and nervous systems. With grants from the National Science Foundation, Kuo investigates ways to break down pesticides to make them safer and is developing methods of recycling phosphate toxins, work that few other scientists have undertaken. In his quest for solutions, he’s collaborated and mentored undergraduates (earning faculty awards in 2014 and 2020), worked with Nobel-prize-winning scientists (Robert Grubbs at Caltech and Thomas Cech at University of Colorado Boulder), earned three patents related to his research and won the 2019 Outstanding Oregon Scientist Award from the Oregon Academy of Science. The recipe for his success is a mix of talent, dedication and collaboration with the next generation of scientists. Why should we be concerned about the supply of phosphorus?
In 2015, the NSF published the report “Closing the Human Phosphorus Cycle” on the need for phosphorus recovery as a national priority. However, the USGS report (January 2021) about the National Minerals Information Center (Phosphate rock statistics and information) indicates a very large supply (67,000 million tons) of crude phosphates in reserve. In the same report, it shows we globally mine 210 million tons of phosphate annually, and this yields a ~300 year supply. But, when you break that number down by nation, the U.S. has only 1,000 million tons in reserve (in mainly Idaho, Florida, North Carolina and Utah), and we mine domestically 24 million tons/year. This yields only a 40-year domestic supply. Most of the mineable phosphate is in hardto-reach areas like the Western Sahara. This got me interested in targeting a greater challenge: it’s not enough to break down phosphate toxins; you have to convert it toward a usable form of phosphorus—it’s about sustainability of phosphorus. We know so well about sustainability when it comes to recycling and
stewarding limited natural resources. This is about recovering an essential element in short supply domestically before it’s too late. This was new territory for me, because it did not entail organometallics (my grad school focus), and the emphasis is directed toward recovery of phosphates not breaking it down. You’ve been working since 2015 on this problem. What have you found?
We’ve shown that small plastic beads coated with molybdenum metal could break down the phosphate pesticides. Moreover, we found one of the products of this breakdown is actually a commodity phosphorus compound used in flame retardants and in plastics. Never in my wildest dreams did I suspect this useful outcome for these polymeric beads. In addition, these same beads broke down the well-known herbicide Roundup (glyphosate) into useable phosphate in water. This is our most recent result, and we were delighted when, last year, we were awarded a patent for this work. My goal is to understand the why, the mechanism. We want to identify the many intermediate steps, then we want to understand the big question: why A (phosphate toxin) goes to D (good phosphate). Why does Roundup in the presence of these beads generate carbon dioxide and nitrogenous compounds? Can we find other types of metal salts that precipitate out the phosphate into, say, fertilizer? So it’s not enough to say, I found a way to go from bad A to good D, we have to understand the intermediate steps. That is one of the underpinnings in my work, and it shows up in almost all my publications. It’s a bit like solving a puzzle when you try to understand the mechanism of a reaction, and this approach towards chemistry stemmed from both my undergraduate and graduate education.

Kuo has shown that molybdenum polymer (beads) could break down phosphate pesticides to volatile organics and watersoluble phosphate.
My undergraduate research with Mits Kubota (HMC professor of chemistry, 1959–2000) impressed on me the importance of metals in chemistry. It directed me to look at graduate programs and research with an emphasis on studying the chemistry of metal complexes. At the same time, I was intrigued with the hybrid of organic and inorganic chemistry. Mits often let me “wander” around his lab looking for reactions that would be interesting to study, and that freedom was what got me interested in chemistry.

What was your grad school focus?
I was trained at Northwestern University as a classic organometallic chemist by one of the best in the field, Tobin Marks. I got the chance (and a teaching/research stipend) to look at one specific organometallic complex. But to really broaden the scope of the work and to find novel applications of organometallics, I had to find “out of the box” hypotheses in organometallic chemistry. I focused on how a class of organometallic compounds, metallocenes, bind to DNA. The molybdenum metallocene was structurally related to another non-organometallic compound called cisplatin, which was one of the leading anticancer drugs at that time. The hypothesis was that the two “cousins” worked in the same manner by binding to DNA. This was unique, because it was one of the few cases where an organometallic compound was investigated for its biological activity in water. In my research group (Tobin Marks at Northwestern), everyone else looked at water-sensitive organometallics that usually decomposed from the moisture and oxygen in air. So, I was definitely the “odd one” where everything I did was in water, and the particular compound (molybdenum metallocene) was stable in water. Around the ’90s, there was a lot of interest in breaking apart phosphates which form the backbone of DNA, and many chemists were looking at how metals could accomplish this transformation. While at Caltech, where I did my postdoc, Jik Chin (McGill University) and I pondered how water-stable organometallics could break down phosphates in water. I had just spent four years looking at how waterstable metallocenes bind to the phosphate backbone of DNA, so it was literally adding two plus two. My first project (and first publication) at Lewis & Clark was applying that guess. In a paper published in Inorganic Chemistry, I wrote that the work was really the first example of an organometallic compound that broke down (“hydrolyzed”) phosphates. You’ve introduced high school and undergraduates to this research. How have they contributed?
To really broaden the scope of organometallics, I had to find other types of phosphates to break down. I wondered, could these organometallic
metallocenes be applied toward breaking down neurotoxic phosphates? With undergraduates at Lewis & Clark, I replicated the synthesis of an analog of the VX nerve agent, one that is extremely safe to use. We put out a half dozen publications showing that the molybdenum metallocene readily degraded this nerve agent analog in a safe manner and, in 2007, were awarded a patent on this work. A subsequent 2015 patent had one undergraduate as a co-inventor; they’ve taken an active role in this endeavor. In 2012, I was pleased to read that my work was reviewed in a Chemical Review article on the destruction and detection of chemical warfare agents. High school students, including my daughter, are working on the use of the plastic beads coated with the metal molybdenum to degrade phosphates. We break it down to volatile organics and water-soluble phosphate. The three carbons of Roundup form carbon dioxide and methyl amine. So you don’t have to separate the byproducts because they bubble off. When we add another metal, we precipitate the phosphate to a white powder (aluminum phosphate). The high school students looked at the acidity and temperature conditions that form this white powder, which is used as a paint additive. We’ve taken a bad neurotoxin and converted it to paint/corrosion inhibitors, thus precipitating out dissolved phosphate into a usable form. For the next goal, we are looking to precipitate it out as fertilizer.
I think of my work as another form of sustainability or green chemistry. We’re taking a toxin—pesticides and herbicides—and we’re recovering it as a valuable commodity chemical.
As global sustainability efforts gain momentum, how does your research on phosphates fit in?
I think of my work as another form of sustainability or green chemistry. We’re taking a toxin— pesticides and herbicides—and we’re recovering it as a valuable commodity chemical. About 15 years ago, this research was couched in terms of national security; the phosphates I was researching were the phosphate neurotoxins in nerve agents, stockpiles of which have since been destroyed. There’s still phosphorus out there, but it’s now in the form of pesticides and herbicides, and so it’s an issue of sustainability. It’s not enough just to degrade the phosphorus, we have to degrade it in a form that’s usable, and more importantly, we have to understand the fundamental chemistry that drives this transformation.
Alumni Awards Selected by the Alumni Association Board of Governors, alumni are honored and celebrated for their achievements to society and to the College community. Outstanding Alumni
Family (Feline?) February Nearly 300 parents and guests attended some portion of our Family February programming, composed of 15 virtual events throughout the month, including information sessions on academic resources, student engagement, a tour of the new Makerspace, a Duck! improv show and a parent-to-parent panel discussion led by members of the Parent Leadership Council. A fun, interactive event, the Bridge Building Competition, encouraged participants “to build a bridge with the materials and people around you.” Kathy Fries P24, Xander Fries ’24 and Luna Loki submitted the entry “Nine Lives.”
“Our goal was to use the material we had accumulated the most of during the pandemic, which was grocery bags. The cats were very interested in the bags the whole time. We weren’t sure whether our bridge was quite in line with OSHA regulations, so only the lightest feline test pilot, Luna, dared the crossing. This challenge was harder than we thought; it took multiple iterations, by the end of which our cats had totally lost trust in our engineering skills.” –Nine Lives team
Alumni April 2021 In collaboration with alumni representatives, staff members in the Office of Alumni and Parent Relations orchestrated a wide-ranging Alumni April with almost two dozen virtual events for alumni across the U.S. and around the world.

Zoom has been a benefit to other types of meetings as well (although I’d be happy to get back to in-person meetings) because there is no travel time involved, so more meetings are possible! Some of our community activities also continue on Zoom or in somewhat artificial socially distanced physical arrangements. We get regular exercise walking the city because that is one of the outside activities that has continued to be allowed. Life is certainly not boring.”

Lights! Camera! Navier-Stokes Equation! Interview by Andrew Faught
as chief technology officer for Animal Logic, one of the world’s leading digital animation studios, Darin Grant ’96 helps make movie magic. His credits at Animal Logic include The Lego Movie 2: The Second Part and Peter Rabbit 2. At Digital Domain and DreamWorks Animation, he worked on Fight Club and How to Train Your Dragon. What is your role as a technologist?
Ultimately, I’m helping to create art. Every single pixel and all the data behind it that goes into an animated feature film relies on technology. Every character, every environment, every piece of clothing, every explosion all have a significant amount of technology involved in their creation. And while the technology is complex and amazing, ultimately my role is a support role. If there was no technology, then we couldn’t make the films that we do today, but we don’t build technology for technology’s sake. How has technology changed in the last 20 years?
When you think back to the early days of film, whether it was live-action movies or 2D animated films, there was a lot of manual labor that went on in creating effects. But nowadays, much of that work is done completely on the computer. Scenes of crashing waves or gigantic explosions are now computer simulations using the Navier-Stokes equations that you might have learned in upper-level physics classes at Harvey Mudd. It’s easier and safer to have actors running away from a digital floods or explosions than to actually have a real flood and put their lives in potential danger. What does the future hold?
Technology always gets better, faster and cheaper. As a result, we are able to create imagery that is more complex than anything
we could imagine when I graduated. But even now, there’s a lot of sitting and waiting for results to be generated. New technology and machine learning will allow us to make changes instantly, changing not just the speed at which we work but how we work. How did your career aspirations come about?
When I was growing up in Cupertino, I was surrounded by computers, and I wanted to be a Disney animator and Alex P. Keaton from Family Ties—technology, animation and business. But I can’t draw worth a damn so I focused on computer science and economics. When I was a junior, Jill Sakata Melosh ’96 orchestrated a tour of a company called Digital Domain that was working on Apollo 13. On
The Lego Movie 2: The Second Part from Warner Bros. Pictures and Warner Animation Group, in association with LEGO System A/S, a Warner Bros. Pictures release
that tour, I saw that I could use computer science to help others create art, or even create that art myself. That was kind of the light-bulb moment. Where do you find inspiration?
I find inspiration from my teams. Ultimately, this is a management job, and I’m responsible for the welfare of over 100 people who support a much larger organization. Professor Gary Evans was a massive influence in this. I had a class with him early on, and he said, “All of you are smart, but you’re going to be stuck following instead of leading if you don’t know how to communicate.” It was a scared straight moment for me, and significant in terms of knowing that success was about more than building technology, it was building teams.

Computing with Nature Megan Wheeler ’13 takes a quantitative approach to solving urban ecological problems. Written by Carol Brzozowski
as an environmental scientist with the San Francisco Estuary Institute’s Resilient Landscapes program, Megan Wheeler ’13 focuses on urban ecology as she experiments with social science and field ecology methods. “It’s thinking about what cities, developers or designers might be able to do to have a positive ecological impact in urban environments,” says Wheeler. “It’s working to improve biodiversity, human health, urban heat, stormwater quality and quantity of runoff.” Wheeler notes that “urban management and design have so much potential to do better to improve the quality of the urban environment for both people and for nature. We tend to overlook the urban environment as a place where nature can be and do well. But there’s a lot of potential for greening and to incorporate nature into the city.” Research shows people have better physical and mental health when they spend time in nature, she says. “They’re more satisfied with their lives. We also know from research that when people have a more personal connection to nature, that can lead them to support conservation more broadly.” While Wheeler was drawn to environmental science and ecology at HMC, she majored in mathematical and computational biology. “It gave me a unique perspective as far as having a strong quantitative and computational background, which is less common in ecology,” she says. “I’m a fairly quantitative person, which is part of what led me to Mudd.” Wheeler credits HMC faculty, like life sciences professor Catherine McFadden and Bernard Field Station director Marty Meyer, for helping her make connections between quantitative skills and ecological questions. Biology professor Steve Adolph introduced
Wheeler to a program at the Marine Biological Laboratory in Massachusetts, where she did a deep dive into ecosystem ecology and environmental sciences. She worked there for a few years before pursuing her doctorate in environmental life sciences at Arizona State University. Two years into the program, Wheeler says she was struggling with academic research. “I kept asking what the problem we were trying to solve was instead of what the interesting research question was.” Seeing the contrasts between the HMC hands-on engineering approach and a more theory-based academic approach led her to understand where she most wanted to make an impact. “I realized I was more excited about trying to solve some of our urgent ecological problems rather than focusing only on creating new knowledge. My current position at the San Francisco Estuary Institute allows me to do some of both.” She’s pursued these goals in many projects since, including a collaborative effort with
the International Union for Conservation of Nature and the International Olympic Commission to study how sports can have a positive impact on nature in cities. Wheeler interviewed people involved in sports federations across the world about how they approach biodiversity and what they thought the opportunities could be for sport to provide leadership in creating spaces for both people and nature. With her team at SFEI, she applied urban ecological research to identify impactful interventions that could increase the ecological value of urban sporting venues. The organizations’ published guide explains how investing in urban biodiversity provides an opportunity for sports federations, venue owners and operators, local organizing committees as well as city planners and investors to build a long-lasting and a socially positive legacy in cities. “People are thinking about sustainability and climate change, but maybe not quite biodiversity yet,” she says. “It’s a frontier.” SPRING 2021

A Seismic Shift Longtime faculty member, earthquake researcher, astronomy expert and alumnus Greg Lyzenga ’75 is retiring after more than a half century on campus it’s been 50 years since Greg Lyzenga ’75 (physics), first became part of the HMC community, when he was admitted to the Class of 1975. He has taught physics to generations of Harvey Mudd students and worked with them on numerous research projects and extracurricular activities, including astronomy and rocketry clubs and competitions. As Lyzenga enters retirement, the HMC Alumni Association celebrated his many accomplishments with a 2021 Outstanding Alumni Award, which recognizes impact on Harvey Mudd College as well as service to society. The Burton Bettingen Professor of Physics, Lyzenga conducts both theoretical and observational studies of the physical processes that lead to earthquakes and tectonic deformation. He uses the Global Positioning System to measure the movement of land along fault lines to determine the amount of strain on these faults before earthquakes and the alteration of the earth afterward. He has published extensively in the area of modeling tectonic plate movement. Before becoming a faculty member at Harvey Mudd in 1990, Lyzenga worked at NASA’s Jet Propulsion Laboratory on the development and interpretation of space-based geodetic techniques. In 2012, he and fellow collaborators received the NASA Software of the Year Award for QuakeSim, a comprehensive software tool for simulating and understanding earthquake fault processes and improving earthquake forecasting. The tool is accessible to a broad range of scientists and end users, including emergency responders, commercial disaster companies, the insurance industry and civil engineers. Recently, he and JPL colleagues have been doing earthquake research, making measurements of the San Andreas fault in the area of the Salton Sea and also in the area of central California near the Ridgecrest earthquake. He’ll continue that work in retirement. Though much of his research is about examining the causes of earthquakes, he’s an inveterate stargazer and science fiction fan. He bought his first telescope at age 8 for $29.95—the insurance money his parents received after his bicycle was stolen. The telescope began Lyzenga’s lifelong activity in amateur astronomy and professional pursuit of understanding planets large and small. In response to our request, Lyzenga is sharing one of his astro calendars, a popular feature in past magazines.
