Profile Introduction

Socioecology of mammals, especially primates; primate origins

Degrees

1990 PhD, Animal Behavior University of California, Davis:
1976 BA, Ethology Johnston College, University of Redlands:

Research Interests

My research interests include primate socioecology, food competition, predation, and dispersal. I'm currently directing a project in Laikipia, Kenya that uses GPS collars to monitor the movements of leopards,baboons, and vervets every 15 minutes around the clock to better understand the relationship between leopards and their primate prey.
