Dr. Kris Sabbi researches the ways that internal and external conditions shape primate behavior between infancy and adulthood. She earned her Ph. D. from the University of New Mexico (2020) studying sex differences in wild chimpanzee social and hormonal development. Before joining the Department of Human Evolutionary Biology at Harvard, she worked as Postdoctoral Researcher with Dr. Zarin Machanda and Dr. Alex Rosati on a research project combining data from sanctuary and wild chimpanzees to better understand the way that human leadership styles evolved. As a College Fellow in HEB, she teaches courses in human life history evolution, hormones and behavior, and research techniques in primate behavior and ecology.
