I am an evolutionary anthropologist and a field primatologist interested in the evolution of social behavior.

My primary research interests are the dynamics of social relationships, mating systems, communication, social learning and traditions, social cognition, cooperation, and life histories. Although I have also studied macaques, the primary species in which I study these topics is the white-faced capuchin monkey, Cebus capucinus.

Since 1990 I have directed the Lomas Barbudal Monkey Project in Costa Rica, which is a long-term study of the behavioral ecology of the white-faced capuchin monkey. This is one of the longest-running and most detailed studies of a primate society in the wild. The data set includes demographic data for 10 social groups, social and foraging behavior data, hormone data, genetic data enabling construction of genealogies, personality ratings, acoustic communication, and video data on gestures.  Further details of the accomplishments and current research associated with this project, as well as information about how to take part in the research, can be found at
