Message from the Chair During the fall semester we have been able to resume some aspects of normal academic life, with students returning to campus and faculty teaching in person for most of our courses. In September, as part of ensuring a healthy and safe campus, the university implemented a mandatory COVID-19 vaccine requirement for all students. We have been pleased by the positive response from students in getting vaccinated and continuing to observe campus protocols, which include wearing face masks, particularly indoors. Currently, more than 85% of students are either partially or completely vaccinated, with similar rates for faculty and staff. We also have seen the number of Covid cases reported on campus remain low throughout the fall semester. We continue to encourage faculty, students, and staff to follow health and safety guidelines to ensure that we finish the semester healthy and safe. Our faculty continue to be recognized with awards and invitations, including receiving a National Science Foundation award. The funding will support research to integrate grain growth experiments, data analysis, simulation, and theory. On another note, two of our professors have been invited to present at the prestigious International Congress of Mathematicians next summer in St. Petersburg, Russia. The invitations are an indication of the importance of the work these professors are engaged in and of the caliber of the department. We are sad to note the passing of Professor Emeritus Les Glaser in October. He spent 34 years as a professor of mathematics and 15 years as the undergraduate advisor in the department. He will be remembered as a terrific mathematician, an excellent colleague, and a devoted undergraduate advisor for our students. We will miss him.

Many undergraduates major in mathematics or science in the hope of doing research one day. Now, the College of Science is offering an innovative program called the Science Research Initiative (SRI) that puts students in a lab as soon as they arrive on campus. As part of our year-end fundraising campaign, we’re encouraging alumni and friends to donate to the SRI program. For more information, please see the article on page 10. We appreciate your ongoing generosity. So much of our work depends on the support of donors to advance our mission of excellence, teaching, mentoring, and research. With best regards,

Yekaterina Epshteyn and colleagues win prestigious National Science Foundation Award Yekaterina Epshteyn, Professor of Mathematics at the University

of Utah, and her colleagues, Katayun Barmak, Philips Electronics Professor of Applied Physics and Applied Mathematics and Materials Science and Engineering at Columbia University, Professor Chun Liu, Department of Mathematics, Illinois Institute of Technology, and Professor Jeffrey Rickman, Department of Materials Science and Engineering and Department of Physics, Lehigh University, have won a four-year $1.8 million award from the National Science Foundation (NSF) in the program category Designing Materials to Revolutionize and Engineer our Future (DMREF). DMREF is the primary program by which NSF participates in the Materials Genome Initiative (MGI) for Global Competitiveness, which recognizes the importance of materials science and engineering to the well-being and advancement of society. The award will fund research to integrate grain growth experiments, data analytics, simulation, and theory. The grant is jointly funded by the Division of Mathematical Sciences and the Division of Materials Research.

Yekaterina Epshteyn

“Our team is extremely happy and grateful for the support provided by the NSF DMREF award,” said Epshteyn. “We’re thrilled to further pursue our interdisciplinary research, contribute to the training of the next-generation materials science and mathematics workforce, as well as work towards increasing diversity and broadening participation within STEM.” Epshteyn received a Ph.D. from the University of Pittsburgh, held a three-year NSF-RTG (Research Training Group) postdoctoral fellow position at the Department of Mathematical Sciences and the Center for Nonlinear Analysis at Carnegie Mellon University, and joined the U’s Math Department in 2010.

About the research

Grain growth is a very complex process and may be viewed as the anisotropic evolution of a large metastable network. One of the main thrusts of the project will be to uncover possible stochastic processes that define the evolution of various statistical measures of grain growth, discover relations among them, and establish links to materials properties. Results from structure-preserving numerical simulations, alongside critical sets of experiments and new experimental data, will be invaluable in navigating the modeling and analysis.

Most technologically useful materials are polycrystalline microstructures composed of a myriad of small monocrystalline grains delimited by grain boundaries. An understanding of the evolution of grain boundaries and associated grain growth (coarsening) is essential in determining the properties of materials across multiple scales. Despite tremendous progress in formulating microstructural models, however, current descriptions do not fully account for various grain growth mechanisms, detailed grain topologies, and the effects of different time scales on microstructural evolution. As a result, conventional theories have limited predictive capability. The goal of Epshteyn’s project is to develop a predictive theory of grain growth in polycrystalline materials through the construction of novel, closely integrated data-driven numerical simulation and mathematical modeling, combined with data analytics, analysis, and a set of critical experiments. This interdisciplinary project, requiring the complementary expertise of applied mathematicians and materials scientists, is firmly aligned with the MGI. The new knowledge and tools that will emerge from the project will have a profound impact on the performance and reliability of polycrystalline materials used in many technologically useful systems and structures, thereby expediting advanced materials development and deployment. Predictive computational algorithms and data will be made available and accessible to other researchers.

The project will also create and employ specific data analysis techniques for the study of dynamic evolution of grains in experimental and computational systems, with the goal of validating and further refining the microstructural models. This component of the project will lead to the development of new materials informatics methods; innovative stochastic differential equations models of grain growth; new mathematical and numerical analysis techniques for coarsening systems; as well as improved computational tools. The results of combined data analytics, modeling, and analysis will be used to guide the design of subsequent experiments. Experimentally, grain growth will be examined in prototypical metallic thin films. Since most elemental metals and many metallic alloys have cubic structures, the proposed studies will have broad applicability.

Department of Mathematics professors selected to present at the International Congress of Mathematicians Two professors from the University of Utah’s Department of Mathematics have

received invitations to present at the prestigious International Congress of Mathematicians (ICM) in July 2022, in St. Petersburg, Russia. The invitations are an indication of the importance of the work these professors are engaged in and of the caliber of the department. First held in Zurich, Switzerland, in 1897, the ICM is the largest and most significant conference on pure and applied mathematics, as well as one of the world’s oldest scientific congresses. ICMs are run every four years by the International Mathematical Union in partnership with host country organizers.

Mladen Bestvina will give a plenary lecture Mladen Bestvina, Distinguished Professor of Mathematics, has been invited to give a plenary lecture. Plenary lectures are given in the part of the conference that everyone attends. An invitation to give a plenary lecture to the thousands of ICM participants is considered a special distinction in the mathematics field, and criteria for selection are rigorous. This is the second time Bestvina has been invited to speak at the ICM. He was a speaker in the topology section in 2002 in Beijing.

Mladen Bestvina

“It is a huge honor for me to be selected to give a plenary talk at the ICM,” said Bestvina. “It’s primarily a recognition of the big advances my field—geometric group theory—has made over the last several decades. When I started my career, the term didn’t even exist, and now geometric group theory has developed into a field involving topology, geometry, and dynamics. In my own work, I always found it more rewarding and satisfying to collaborate with others. Over the years I wrote papers with many collaborators, but I’d like to mention three with whom I wrote quite a few papers and who deserve a lot of credit for my invitation to speak at the ICM: Professor Ken Bromberg, who teaches in our Math Department; Mark Feighn, Professor of mathematics and computer science at Rutgers University; and Koji Fujiwara, a math professor at Kyoto University in Japan.”

Bestvina’s research Bestvina’s research focuses on symmetries of objects (called “groups” in mathematics) from the point of view of geometry and topology. For example: imagine an infinite chess board—the plane with the usual tiling into squares (ignore the colors of the squares that a chess board would have). What is the group of symmetries? An example of a symmetry is a translation of the entire board by a whole number of squares in the direction of a side of a square. In the language of geometric group theory, this group is “virtually Z+Z.”

“Conversely, suppose someone hands you a group and asks you to understand it,” said Bestvina. “Then you would build an object (a ‘space’) whose group of symmetries is the given group. If the group is virtually Z+Z, you would build the plane and understand the group using Euclidean geometry you learned in high school. There are more complicated groups, and building corresponding spaces and understanding their geometry is a lot of fun,” he said. Bestvina received the University of Utah’s Distinguished Scholarly and Creative Research Award in 2019. He was born in Croatia and received a Ph.D. in mathematics from the University of Tennessee. He joined the U as a professor in 1993 and became a Distinguished Professor in 2008.

Jon Chaika will give an invited lecture Jon Chaika, Associate Professor of Mathematics, will give an “invited lecture.” Chaika will present jointly with Barak Weiss, Professor of mathematics at Tel Aviv University. Invited lectures are organized into sections, and Professors Chaika and Weiss will present within the “Dynamics” section. “I’m excited for the opportunity to present my math at the ICM,” Chaika said. “The ICM is such an important gathering of the international mathematical community, where we share ideas and discuss and disseminate the latest advances in active research in mathematics.”

Chaika’s research Chaika’s research is in the field of dynamical systems, which seeks to understand a space and a map by following individual points. This map could represent the passage of time in a physical system. Ergodic theory is a sub-branch of dynamical systems that uses an idea called a measure to do this. A measure is an abstraction of the idea of length or area (or volume). One of the families of systems Chaika studies is billiards in polygons. In these systems, a point travels in a straight line inside a polygon until it hits one of the sides. Once it hits a side, it obeys the law of elastic collision, bouncing off the side the same way a billiard ball would bounce off the side of a pool table. The point then continues to travel in a straight line until it hits the next side, where it again has an elastic collision. Chaika and Giovanni Forni, a mathematician at the University of Maryland, have been able to show there are billiards in polygons in which the flow in different directions is usually uncorrelated.

Jon Chaika

Chaika received a Simons Fellows Award in Mathematics in 2020. He obtained a Ph.D. in mathematics in 2010 from Rice University and joined the University of Utah in 2013. “It’s an honor for the U to be so prominently represented at the ICM,” said Davar Khoshnevisan, Professor and Chair of the Department of Mathematics. “We congratulate our colleagues Mladen and Jon and are proud of the international recognition their work is receiving.”

ALUMNUS PROFILE

Bob Peterson Bob Peterson’s journey through life

has taken him many places. He was born and raised in the small town of Plentywood in northeast Montana, near the borders of North Dakota and Saskatchewan, Canada. He graduated from the University of Utah in 1971, with bachelor’s degrees in mathematics and history; he went on to receive a master’s degree in engineering administration from the U in 1975. He spent time in Tonga with the Peace Corps and later worked for more than 30 years for King County (in Seattle), most recently as a tribal government relations officer.

Education at the U “When it was time to apply to college, I was encouraged by my parents to look at other universities, other states, and other environments,” said Peterson. “I considered Washington, where my mother’s family were territorial pioneers, as well as Minnesota, where the Peterson family homesteaded. The University of Utah won the day, with its mountains and deserts and generally warmer climate and, of course, the university’s reputation. I learned later that my mother had attended the University of Utah in 1946. I wonder if that had something to do with my choice!” Peterson says his education at the U instilled a foundation for learning that has continued throughout his life. “I was always curious and read a lot of history, law, and philosophy, and the U’s environment and teaching ethic helped me to think broadly and seek the positive in the world.” He also appreciated the different teaching methods that he observed in the Math Department. “The teaching was rigorous, thorough, creative, and thought-provoking,” he said. While he didn’t do any specific mathematics research at the time, he did work on applied numerical analysis, operations research, and computer applications during grad school. “I recall late nights at the Merrill Engineering Building waiting for a keypunch machine to become available,” he said.

Bob Peterson On campus, he lived two years in Bailiff Hall (which no longer exists) and then moved off campus, working in the housekeeping department at the Hotel Utah Motor Lodge on North Temple (now demolished). Later, he worked full-time at Kennecott Copper’s Bingham Canyon Mine. It was a supportive workplace, and the mining, industrial, and civil engineers who were his coworkers encouraged him to work on an engineeringrelated graduate degree, so he began graduate studies at the university.

Stint in the Peace Corps While working at Kennecott, Peterson realized he wanted to do more with his life. Fortunately, Kennecott was willing to provide a leave of absence to Peterson to allow him to join the Peace Corps. “Joining the Peace Corps allowed me to broaden my personal focus from a single extractive industry, like mining, to the larger world of different cultures and peoples and aspirations,” he said. In 1976, he was assigned to Tonga PCV Group 17 as a development analyst in the Kingdom of Tonga’s Ministry of Labour, Commerce, and Industry. He was also assigned to teach part-time an introductory economics course at ‘Atenisi University. The work of a development analyst included evaluating foreign aid proposals, providing guidance on facility siting, and working with local officials on price controls. By this time the Peace Corps had an affiliated agency—Volunteers in Service to America (VISTA)— so in late 1977 and early 1978, Peterson was able to


transfer to a VISTA position, again as a development and policy analyst, in Kodiak, Alaska. He worked with the Kodiak Area Native Association (KANA) and six island native villages on rural subsistence and energy issues, as well as building a village health clinic.

Career with King County He met his wife, Susan, and her two children in Kodiak, and they became a family. In 1980 they moved to Seattle, where Peterson served as director of an intertribal engineering and planning consortium (Puget Sound Association of Cooperating Tribes). In 1984 he accepted the position of tribal general manager for the Suquamish Tribe in the Puget Sound area. Further broadening his work in tribal advocacy, he testified to congressional subcommittees on tribal government and contracting issues. In 1988 Peterson accepted a project manager position with the King County/Metro Wastewater Treatment Division, working on water quality issues with tribal governments. He subsequently established and directed an agency-wide Tribal Initiatives Program, while advocating tribal positions and treaty rights within a local county government.

Susan and Bob Peterson

Peterson says his education at the U, as well as his work in the Peace Corps and in Alaska, gave him the skills and experience to work successfully in tribal relations. “The U gave me the necessary technical skills,” he said. “Then working within a monarchy in Tonga and with the Kodiak Area Native Association’s tribal villages in Alaska gave me the confidence to move into Pacific Northwest tribal affairs.” In 2018, Peterson retired from the King County/Metro Department of Natural Resources and Parks as a tribal government relations officer. In honor of Peterson’s outstanding work, the King County Executive issued a proclamation declaring June 1, 2018, as “Bob Peterson Day.” Today, Peterson and Susan (also retired from King County after 26 years) live in Mount Vernon, Wash. They enjoy their eight grandchildren and keep busy reading, writing, and teaching adult GED math classes through the Skagit Community Action Program. They celebrated their 40th wedding anniversary last May.

STAFF PROFILE

Angie Gardiner Angie Gardiner, who joined the Department of Mathematics in 1998, has begun a new position as Program Manager for the department.

What was your previous job title? Before moving into the Program Manager position, I worked for nine years as the Academic Advising Coordinator and Bridge Advisor for the department. During this time, I also served as the Coordinating Advisor for the College of Science for several years. Prior to that, I worked for 14 years as the Director of Undergraduate Services in the department, overseeing the T. Benny Rushing Mathematics Center (tutoring center and computer lab).

What are your new duties? I am now the Program Manager for the undergraduate program in the department. In this new position, I work with the Chair, Associate Chairs, Program Directors, and Course Coordinators to gather assessment data and help monitor and continuously improve our programmatic offerings.

How will this benefit our math students and/or faculty? In this role I hope to help the department administration and faculty use data to assess various aspects of our undergraduate program in a way that maybe we haven’t been able to do before. This can help the department make decisions about offerings (whether it be courses, programs, or extra-curricular opportunities) in a way that will best serve our students.

Angie Gardiner

What was your undergraduate degree? I graduated from the University of Utah with a BA in Mathematics and a minor in French in 1997.

What do you enjoy about working in the department and working with students? I firmly believe that education is the key that opens doors to opportunity. As an advisor, I had the privilege of working individually with students, helping them find the resources and experiences to reach their goals. I consider myself lucky to have been a part of so many students’ educational journeys. As Program Manager, I’m excited to continue working on behalf of students in a different way—making sure that our program is delivering the right educational opportunities in the best way possible. One thing I’ve enjoyed about all of my jobs with the Math Department is the feeling that my work makes a positive difference in the lives of students. I also truly enjoy the people in the department! The staff and faculty are committed to student success, and the students work hard to achieve their goals. Working with such dedicated people makes the department a wonderful place to be.

In memoriam: Professor Emeritus Les Glaser Professor Emeritus Leslie “Les” Curtis Glaser died

October 16, 2021, in Salt Lake City, surrounded by his wife of 63 years, June, his children, and many of his grandchildren. In the Department of Mathematics, Les was considered a terrific mathematician, an excellent colleague, and a devoted undergraduate advisor for our students for many years. We will miss him. He was born September 4, 1937, in DeKalb, Illinois, to Hazel (Miller) and Louis Conrad Glaser. His older brother, Robert, preceded him in death. Les earned an undergraduate degree from DePauw University, where he was a member of the Sigma Alpha Epsilon fraternity. He received a master’s degree and a Ph.D. from the University of Wisconsin, Madison. He was a recipient of a National Science Foundation post graduate award. Les began his professional career at Rice University, where he was an assistant professor of mathematics for four years. He and June moved to Salt Lake City, where he spent 34 years as a professor of mathematics at the University of Utah and 15 years as the undergraduate advisor.

Les Glaser, Professor Emeritus

He was the recipient of an Alfred P. Sloan Fellowship and was a member of the Institute for Advanced Study in Princeton, NJ. He wrote numerous research papers and was the author of Geometrical Combinatorial Topology Vol. I and Vol. II. Les was a food and wine lover and spent 17 years as the president of the Wasatch Mountains Food and Wine Society. He and June loved to travel, especially to France. They also enjoyed trips to Alaska and Italy. Les is survived by his wife, June Ellyn (Higgins); his children, Robert (LeeAnn Inadomi), Las Vegas, Nev.; Laurie Daugherty (Steve) of Salt Lake City; Lynne Sutherland, Sandy, Utah; and Richard (Joyce) of Salt Lake City; eight grandchildren; and two great grandchildren.

Please contribute to our Science Research Initiative Program Many undergraduates major in science in the hope of doing research someday. Others are curious about doing research but unsure about how it aligns with their talents and interests. Now, the College of Science is offering an innovative program called the Science Research Initiative (SRI) that puts students in a lab as soon as they arrive on campus. “The most consequential learning happens by doing, and that is especially true in the College of Science,” said Peter Trapa, Dean of the college. “Experiences in a laboratory-centered, team-based, interdisciplinary environment give students the skills to succeed and access opportunities in high-paying industries,” he said. “The SRI offers incoming students, with no prior exposure to research, the opportunity to learn alongside their peers to gain hands-on, technical expertise, and learn directly from researchers as early as their first year at the U. The college’s exceptional faculty, world-class research facilities, and commitment to in-person experiential learning make this unique program possible.”

10

How the SRI works Any student admitted to the College of Science can apply. During the first semester, the cohort of SRI undergraduates takes a course that prepares them to work in a research lab. The course teaches basic research techniques, the principles of scientific inquiry, and breaks down the structure of lab, such as the roles of graduate students, postdoctoral researchers, and the principal investigator. After learning about the research projects, known as “research streams,” the students rank the labs they’d most like to experience. The program matches them to an SRI faculty scientist leading the project where they will work during the second semester. Then, SRI mentors help each student figure out a path forward, whether it be continuing with the research stream, switching projects, or even leaving lab-based research altogether.


Here’s what some of our students say Eliza Diggins joined the program as a freshman to get research experience and find a thesis topic. She is now a sophomore with a double major: applied mathematics and physics. “I got involved in the SRI during my first semester so that I could get some research experience, and it’s been great,” she said. “Not only was I provided with a research opportunity, but I also had the chance to help design the research. Unlike many undergraduate research experiences, where the student is often only a source of labor, my SRI research stream was driven by the students. We chose our project and got to choose how best to pursue it. This sort of academic freedom allowed us to push ourselves to learn and explore subjects and ideas that wouldn’t normally be explored in our majors.” Ethan Lame is a junior majoring in physics, with an emphasis in astronomy and astrophysics.

SRI Stats • 100 new students enrolled for fall 2021—a total of 150 students. Students are all College of Science majors or undeclared, with an interest in science • 30% of students are from out of state • 18-20 faculty stream leaders will be leading research beginning in the spring semester

“I was honestly very nervous to participate in research,” he said. “I had never really done anything like it before. I was concerned about the time commitment, and I hardly knew where to start. I just reached out to a professor who was working in an interesting field related to my major, and we had a meeting where we were able to figure out a way for me to work over the summer on a project (with his guidance), so I had plenty of free time to do so. “Since then, it’s been a very exciting, and admittedly humbling, experience. I’ve learned more than I ever would have expected, and I’ve made some connections with people who are a few years ahead of me in their academic careers. They’re a great resource to talk to if I have questions about my future.”

How to contribute to the SRI The SRI program relies significantly on donations for its budget. “As we close 2021, we’re inviting alumni and friends of the department to make it possible for students to participate in valuable, exciting, and rewarding research,” said Davar Khoshnevisan, Professor and Chair of the Department of Mathematics. “The SRI enriches the learning experience and helps attract talented students to the department.” To make a donation to the SRI program, visit giving.utah.edu/math
