Overview of Research

My research focuses on the behavioral ecology and conservation biology of the living primates. Nonhuman primates are excellent models of human behavior and evolution because of their social, ecological, and behavioral similarity to humans. Much of my research examines two inter-related areas of primate ecology and conservation biology: (1) the costs and benefits of group living for male and female primates, and (2) the influence of resource abundance and distribution on the feeding and ranging ecology of primates. My past and present research focuses on wild populations of monkeys in East Africa, including Kenya, Rwanda and Ethiopia. By studying nonhuman primates in their natural settings, I can monitor the interactions between behavior and ecology within the selective environments in which these interactions evolved. My research aims to shed new light on the biological processes that shape the behavior and ecology of humans and other animals.  

Currently, I am investigating the behavioral ecology and conservation biology of the rare and enigmatic gelada monkey (Theropithecus gelada) at a remote field site in northern Ethiopia called Guassa. Guassa is an unusually ecologically pristine alpine grassland that has been conserved by one of the few surviving ancient indigenous conservation initiatives on the African continent. My current research at Guassa focuses on evaluating the use of Geographic Information Systems (GIS) and remote sensing techniques to better understand (a) the patterns of abundance and distribution of geladas over space and time and (b) the ecological factors that influence gelada ranging patterns. I am also investigating the key social and ecological variables that influence the outcome of aggressive encounters between gelada social units and the nature and extent of feeding competition within gelada units and how this competition shapes gelada social structure. I welcome student participation and collaboration on my research in primate behavioral ecology and conservation biology. For more information about my research on geladas at Guassa, please visit the Guassa Gelada Research Project Website.
