I study behavioral ecology and physiology, with a particular interest in reproductive health.  My research examines how social and ecological factors can impact behaviors and biological markers, primarily hormones.  The majority of my work focuses on sexual strategies and reproductive physiology of nonhuman primates.  

My current research projects include long-term monitoring of red colobus monkeys in anthropogenically modified habitats in Kibale National Park, Uganda, examining behavioral and hormonal variation in high-ranking male rhesus macaques on Cayo Santiago, Puerto Rico, and calculating reproductive parameters of spider monkeys in Yasuní National Park and Biosphere Reserve, Ecuador.
