JSMF Postdoctoral Fellow

Department of Biology, University of Pennsylvania


I am a James S. McDonnell Foundation Postdoctoral Fellow in the Department of Biology at the University of Pennsylvania and an affiliate of the Penn Center for Mathematical Biology. My postdoctoral mentor is Joshua Plotkin.

I completed my PhD in Applied and Computational Mathematics at Princeton University, where I was fortunate to be advised by Simon Levin, Naomi Leonard, and Corina Tarnita. Prior to that, I completed my bachelor’s degree in Physics and Sociology at Yale University.

As a mathematical biologist and an applied mathematician, I use tools from evolutionary game theory, dynamical systems, and network science to explore mathematical and computational models of collective and emergent behavior in social systems. I am especially interested in understanding how inter-individual differences and population structures influence and are influenced by collective dynamics. My recent projects have focused on self-organized division of labor in ant colonies, hierarchies in adaptive networks, and cooperation and polarization in group-structured populations, among others.
