I am an evolutionary ecologist who studies humans. My main interest is in how the evolution of fancy social learning in humans accounts for the unusual nature of human adaptation and extraordinary scale and variety of human societies. Humans are more widespread and successful than any other vertebrate. Simultaneously, humans are unlike any other animal in that we cooperate in very large groups of unrelated individuals. I and my colleagues use formal evolutionary models, experiments and ethnographic fieldwork to address these puzzles.

You can listen online to a fairly general talk that presents my approach to human behavior.

And here's a more recent talk about the intersection of cultural evolution and evolved psychology.

Since my work tends to lie at the intersection of evolutionary and cultural anthropology, I sometimes do a good job of displeasing both sides!

Current Projects

Been working on a PhD-level stats book, herding no less than three post-docs somehow, analyzing huge amounts of foraging data with Jeremy Koster, and modeling the dynamics of scientific beliefs. Also, I'm being a dad. Hoping to get back to doing anthropology sometime soon.
