Cristina Moya is a Postdoctoral Research Fellow in the Human Evolutionary Biology Department at Harvard University. Her research focuses on how humans adapt to culturally-structured social worlds. Her primary research areas focus on how people reason about cultural group boundaries and make reproductive decisions. She uses ethnographic, developmental psychological, and cross-cultural comparative methods to address these questions. She has conducted extensive fieldwork along the Quechua-Aymara language boundary in the Peruvian Altiplano to understand the nature of reasoning about linguistic social groups.
