Research Focus

My general research program integrates the behavioral endocrinology of primates with their ecology and evolution. I aim to understand how individuals respond behaviorally and physiologically to their social and physical environment, and how these responses influence individual survival and reproduction.

Behavior is the fundamental means by which animals respond to their environment. Behavior is best described as the nervous system’s response to internal and external stimuli – a response that is carried out by the muscular and endocrine systems. As such, hormones play a critical role in facilitating behavior. For group-living animals, responses to both the social and physical components of the environment can have important effects on the evolutionary consequences, in terms of survival and reproduction, of different behaviors.

The study of individual behavioral variation is paramount to understanding how and why behavior has evolved, and how animals adapt to different and changing environments. This is especially important given the extent of habitat modification and climate changeand increasing threats to biodiversity. Field studies of behavioral endocrinology, and the emerging field of conservation endocrinology, can inform us about species adaptability to change by examining hormonal responses of organisms to their changing environments. My primary field research is on vervet monkeys living on the shores of Lake Nabugabo in Uganda, but I also conduct research on vervets at Lewa-Borana Conservancy in Kenya, and collaborate on projects with the Toronto Zoo and on savanna chimpanzees in Senegal.
