Before joining the faculty at Cal State Fullerton, I was a Research Scientist with the Pittsburgh Zoo. I have conducted conservation and research projects in several sub-Saharan African countries, including Kenya, Rwanda, and Ethiopia. I grew up in Williamsburg, VA and earned my Bachelor’s degree in Anthropology and Biology at the College of William and Mary. In 1999, I earned my Ph.D. in Anthropology from Columbia University, where I studied under Dr. Marina Cords, a leading expert in forest monkey behavior and ecology. Dr. Cords oversees one of the longest running field projects on forest monkeys in Africa, at Kakamega Forest, Kenya. For my Ph.D., I lived in a rustic cabin on the edge of the Kakamega Forest for a year and a half studying (a) the ecological determinants of feeding and ranging behavior in eastern black and white colobus monkeys (Colobus guereza) and (b) the strategies adopted by male and female colobus during encounters between groups. After earning my Ph.D., I completed a one-year postdoctoral fellowship with the Wildlife Conservation Society (WCS). At WCS, I conducted a study of the costs and benefits of group life for another colobus monkey species (Angolan colobus or Colobus angolensis) that forms unusually large groups of over 300 members in Rwanda's Nyungwe Forest - one of the largest remaining montane rainforests in Africa. After completing my post-doc, I taught at Columbia University, Queens College, and Seton Hall University before becoming a Research Scientist with the Pittsburgh Zoo in 2002. During my six years at the Pittsburgh Zoo, I expanded my research program at Kakamega, Kenya and, in 2005, established a new research site at Guassa, Ethiopia, where with Dr. Nga Nguyen, I co-direct the Guassa Gelada Research Project, a longitudinal study of the behavioral ecology and conservation biology of the gelada monkey (Theropithecus gelada).

Colobus guerezaTeaching Interests:
I primarily teach courses in the Evolutionary Anthropology wing of the Anthropology Department, including ANTH 101: Introduction to Biological Anthropology, ANTH 301: Primate Behavior, ANTH 454: Primate Conservation, ANTH 490T Current Controversies in Primate Behavior, and ANTH 504T Field Methods in Primatology. I also regularly teach courses in the Environmental Studies (ENST 500: Environmental Issues and Approaches) and Honors (HONR 301T: Globalization and the Environment) programs.

Research Interests:
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.   

Theropithecus GeladaCurrently, 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 (for more information, visit the Guassa Gelada Research Project website).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 gelada feeding and nutritional ecology and what it can tell us about theropith and hominin dietary evolution. I am also part of a large collaborative project with other American, Ethiopian, German, and Norwegian scientists to determine the distribution and abundance of geladas across the Ethiopian Highlands. This project will help identify the conservation threats facing geladas and how they can be mitigated. I welcome student participation and collaboration on my research in primate behavioral ecology and conservation biology.
