LSA Collegiate Fellow &
Incoming Assistant Professor of Mathematics & Complex Systems

University of Michigan

I am an applied mathematician and a theoretical biologist at the University of Michigan, where I am an LSA Collegiate Fellow (2026–) and an incoming Assistant Professor (2027–) in the Department of Mathematics and the Center for the Study of Complex Systems.

I use mathematics and computation to study social processes, in both biological collectives and human societies. My work brings together methods from applied mathematics — including game theory, dynamical systems, and stochastic processes — with theory and concepts from evolutionary biology and social science. Recent research interests include:

  1. reciprocity mediated by reputation, communication, and social norms;
  2. prosocial decision making in dynamic environments; and
  3. the emergence of social structures and their effects on collective behavior.

My group will be recruiting motivated students and postdocs interested in mathematical modeling of social dynamics. Prospective applicants with backgrounds in mathematics, physics, biology, computer science, quantitative social science, or related fields are encouraged to reach out. Please email me your CV and a brief statement of your research interests.
