Welcome.

mattzeffermanI am an evolutionary social scientist fascinated by human ultrasociality, our ability to organize ourselves into societies capable of large-scale cooperation and conflict. In my research, I use the mathematical tools of game theory, evolutionary theory, network theory and institutional design to understand the cultural origins of human cooperation, especially in the context of war. I am now following up on the mathematical theory with ethnographic fieldwork and laboratory experiments as a postdoctoral fellow at the Adaptation, Behavior, Culture and Society research group in the School of Human Evolution and Social Change at Arizona State University.

I was previously a postdoctoral researcher at the National Institute for Mathematical and Biological Synthesis and a member of the Cultural Evolution and Human Behavioral Ecology Labs at the University of California, Davis.
