My research explores how ecological and social factors affect variability in behavior, psychology, and physiology in small-scale societies. To address research questions I use principles from behavioral ecology and life history theory, which attempt to explain modern human variation as an adaptive response to trade-offs between investments in competing demands.

I collaborate on the Tsimane Health and Life History Project ( The project aims to study growth, senescence, demography, economics and health under conditions representative of human evolutionary history.
