I investigate links between conservation and evolutionary theory, with a focus on dispersal, reproductive patterns, social bonds, and genetic structure. The broader goal of my research is to understand how these links translate into conservation outlooks for primate populations that experience different types of anthropogenic interactions. I am a co-director of the Boabeng-Fiema colobus project in Ghana. Research at this site is key for the long-term survival of the critically endangered black-and-white colobus (Colobus vellerosus) that are the focus of the study. I also maintain a long-term research collaboration in the Área de Conservación Guanacaste in Costa Rica, which is inhabited by three primate species (Alouatta palliata, Ateles geoffroyi, and Cebus capucinus imitator) with different dispersal patterns, social organizations, diets, and habitat requirements. In this study system, my research aims to determine whether their behavioral flexibility and genetic variation are sufficient for coping with the rapid environmental changes that these, and most other primate populations, are currently experiencing.
