I am interested in the evolutionary, cultural, and psychological processes through which complex human organizational patterns emerge. My approach consists largely of developing and analyzing mathematical and computational models of dynamic populations, which are informed by research across many disciplines. Some areas of study closely related to my work include social and cultural evolution, social identity and group formation, mate choice, institutional mechanisms for cooperation, social and cultural constraints on decision making, cognition, biological pattern formation, agent-based modeling, and the philosophy of modeling.
A spatial prisoner’s dilemma model with mobile agents, de-coupled birth-death events, and harsh environments.
A general model of human mate choice in which agents are localized in space, interact with close neighbors, and tend to range either near or far. At the individual level, our model uses two oft-used but incompletely understood decision rules: one based on preferences for similar partners, the other for maximally attractive partners.
