Postdoctoral Scholar, University of California Santa Barbara

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.

I am a postdoctoral scholar at the University of California Santa Barbara under the direction of Michael Gurven and Hillard Kaplan.  My research is conducted in collaboration with the Tsimane Health and Life History Project, the UC Santa Barbara Human Biology and Biodemography Lab, University of Washington Biological Anthropology and Biodemography Lab, the Broom Center for Demography, and Center for Studies in Demography and Ecology.
