I am interested in understanding how human cultural practices evolve and, relatedly, how they shape psychology and behavior. My current work examines 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. As part of this, I do fieldwork in Zapotec communities of the Sierra Norte of Oaxaca, Mexico.
