My research focuses on field and laboratory analyses of hormone-behavior interactions; specifically the relationship between reproductive hormones, immune function, behavior, environment, and the implications this has for human health and life histories. My research interests include evolutionary medicine, demography, prostate cancer, risk taking behavior, costly signaling, and the development of novel population level biomarker assays. I manage laboratory analyses conducted by the Tsimane Health and Life History Project, including our mobile and clinic labs as well as the UCSB Human Biodemography Wet Lab.
