Cristina Moya is associate professor of Anthropology at the University of California, Davis. She takes an evolutionary approach to understanding why human social behavior and cognition is different from that of our primate relatives, and how it is culturally patterned. She conducts research in the Peruvian Altiplano along the Quechua-Aymara language boundary and using cross-cultural datasets to investigate how people think about ethnic categories, why social relations influence reproductive decisions, and why some people adopt new and costly behaviors such as religious pilgrimage, while others resist.
