Academic Interests

I am a biological anthropologist with research interests in applied animal behavior and primate behavior and ecology. I have over 20 years of experience studying primate behavior, and have conducted research in Kenya, Grenada, at the San Francisco ZooSafari West Wildlife Preserve, and at CRES (Center for Reproduction of Endangered Species) at the San Diego Zoo. I am currently a Research Associate at Oakland Zoo. Most recently, I have been involved in behavioral enrichment research involving ring-tailed lemurs, chimpanzees, and sun bears, as well as a study of the social network of hamadryas baboons.


Biological anthropology, primate behavior and ecology, applied animal behavior, evolution of human and primate behavior 


I have been a faculty member in the Anthropology Department at Sonoma State University since August 2002. A dedicated teacher-scholar, I have won several teaching, scholarship, and mentoring awards during my time at SSU, including the SSU Excellence in Teaching Award (2009), an Educational Experience Enhancement Award (2015), and the President’s Excellence in Scholarship Award (2016). In addition to teaching anthropology courses in primate behavioral ecology, evolution of human behavior, human behavioral ecology, and anthropological theory, I have been an adjunct faculty member in the Biology Department since 2003. I was the coordinator of the Human Development Program from November 2014-May 2020 and the coordinator of the Liberal Studies-Ukiah Program from January 2018-July 2019. I currently serve as the School of Social Sciences Faculty Associate Dean.
