I earned my A.B. in Anthropology from Washington University in 1995, and received my A.M. (1999) and my Ph.D. (2003) from the University of Illinois in Urbana-Champaign.

CURRENT PROJECT

My main research interest is primate behavior and ecology. I have a regional interest in Central and South America, with a focus on New World monkeys. I have worked in Costa Rica, and more recently conducted research in Brazil. My research has focused on the mixed species groups of three monkeys, Goeldi's monkey ( Callimico goeldii ), red-bellied tamarins ( Saguinus labiatus ), and saddle-backed tamarins ( Saguinus fuscicollis ). These three species form groups of 5 to 15 individuals with other members of their own species, but also form larger groups in which all three species forage, travel, and even feed at the same resources together. Study of mixed species groups (polyspecific associations) is a key approach to understanding why many primates are gregarious (live in groups), and the ecological costs and benefits of group-living. I am also very interested in conservation, especially in Neotropical environments, and the interaction between human communities and environmental conservation.
