I am interested in understanding how human cultural practices evolve and, relatedly, how they shape psychology and behavior. In particular, I study how social norms and institutions– such as those governing kinship, economic exchange, and community structure– impact how people think and behave. My research combines cultural evolutionary theory with methods from anthropology, psychology, and behavioral economics. Recently, I have begun working with the Zapotecs of the Sierra Norte of Oaxaca, Mexico.
