Postdoctoral research fellow in theoretical biology, Monash University I'm interested in the origins of diversity at several scales - including species in ecosystems, ecotypes within species, and cultural variation among people. I also study the interaction between evolution and self-organization more generally, especially co-evolution of social structures and individual behavior. I mostly use agent-based and cellular automata models. I work in Professor David Green's lab and you'll find some of my simulations at his VLab
