I received my B.A. degree in Anthropology (concentration in Biological Anthropology) from the University of California, San Diego in 1994. I received my M.A. and Ph.D. degrees in Anthropology from the University of California, Davis in 1997 and 2002, respectively. I have been a faculty member in the Department of Anthropology at Sonoma State University since August, 2002.

Current Research:

I am a biological anthropologist with research interests in primate behavioral ecology, including polyspecific associations, evolution of primate social systems, and anti-predator behavior. My previous research has focused on sub-specific sociality differences in captive orangutans at the San Diego Zoo, the social behavior of mona monkeys on the island of Grenada, and anti-predator behavior and habitat use of vervet and patas monkeys in Kenya. My current research focuses on Applied Primate Ethology, the application of scientific methods of studying primate behavior to real world problems. The Sonoma State University Primate Ethology Research lab helps match advanced undergraduate and graduate students with projects that local zoos are interested in conducting so that they can better understand the animals they care for.
