She then returned to school to receive a PhD in mathematical sciences. She joined the mathematics department at BYU in 2011. Her research interests include finite elements for domains with fractal boundaries, biological modeling, computational mechanics and the mathematics of computer animation.

### Robert Snellman, Acting Associate Director

Robbie Snellman is an Assistant Professor in the Department of Mathematics at BYU. Robbie received BS and MS degrees in mathematics from the University of Utah, and a PhD in mathematics from the University of California, San Diego. For his doctoral work, Robbie worked in two areas, (1) special values of L-functions, and (2) p-adic Hodge theory. Upon coming to BYU, Robbie pivoted from algebraic number theory and p-adic representation theory to work with students in the ACME program and network science. He currently works with two of his colleagues on problems related to Family Search and genealogical research. He is currently serving as the chair of the calculus committee in the department.

He received BYU's Class of 1949 Young Faculty Award in 2018.

### Mark Kempton

Mark Kempton is an assistant professor at BYU. He received his Ph.D. in Mathematics from the University of California, San Diego in 2015 and was a Postdoctoral Research Fellow at Harvard University from 2015 to 2018. His research interests include linear algebra, combinatorics, graph theory, matrix theory, and quantum information.

### Benjamin Webb

Benjamin Webb received his Ph.D. at Georgia Tech Institute of Technology in 2011, where he was the recipient of the 2011 Top Graduate Student Award for the School of Mathematics. After his time as a visiting assistant professor at BYU and a Postdoctoral Associate at Rockefeller University, Dr. Webb became an assistant professor at BYU. His general research interests are in the theory of dynamical systems specifically as it applies to the dynamics of real and theoretical networks.

### Jared Whitehead

Jared Whitehead received his PhD from the University of Michigan in Applied and Interdisciplinary Mathematics in 2012. He then worked as a postdoctoral research scholar in the Center for Nonlinear Studies at Los Alamos National Laboratory from 2012-2013 before joining the Mathematics Department at BYU as an Assistant Professor. After being promoted to Associate Professor, Jared has been working as the graduate coordinator for the Mathematics Department. Jared has worked with scientists from a variety of disciplines including physics, meteorology, oceanography, geology, climate sciences, and mechanical, civil, and electrical engineering. His research has focused on the analysis and computation of partial differential equations (PDE) as well as the merging of classical mathematical modeling techniques with modern data analysis and collection. His research truly spans the breadth of the ACME program, from classical mathematical physics to modern methods applied to data science.
