I develop mathematical models to study the evolution of helping behaviors (cooperation, altruism) and harming behaviors (exploitation, spite). I try to understand and disaggregate the role of ecological, demographic, life-history, and cultural factors for the evolution of these behaviors. My research is done in Marcus Feldman's lab in the Department of Biological Sciences at Stanford University.
