- Labs & Research Centers
I am an evolutionary anthropologist interested in the physiology and psychology of contemporary humans, with a focus on small-scale societies. Most of my research investigates the degree to which ecology & culture can penetrate cognition, ranging from low-level perceptual processes to higher-level decision-making processes. Some projects I’m currently working on include the effects of the local environment on risk & time preferences, early life socioeconomic effects on behavior, and I dabble a bit in the evolutionary biology of senescence. I am a member of the Reproductive Ecology Laboratory. I also collaborate with the Yale Psychology Department through the Human Cooperation Lab and the Social Cognitive Development Lab. My fieldwork is primarily conducted in South America with the Shuar of eastern Ecuador, as part of the Shuar Health and Life History Project.
