Research Interests

I am a theoretical biologist interested in the evolution of complex biological and social organization. Mostly, I work on how individuals with conflicting interests evolve to cooperate with each other, in contexts varying from plant-microbe mutualisms to animal and human behavior. Please check the lab website for ongoing research projects and opportunities for joining the lab.

Courses Taught

BIOL 240: Ecology: From Individuals to Ecosystems (Fall, with Brent Helliker)
