About

Lynne Isbell studies primates to understand them as mammals, as members of ecological communities, and as building blocks to our own behavior. She focuses on their behavior and ecology, but she is also interested in their evolutionary history. Natural history and fieldwork are her preferred guides for greater understanding. Professor Isbell has published on multiple topics, including predation, food competition, dispersal, the ecology of primate social organizations, the evolution of bipedalism, and the origin of primates. She is a past president of the American Society of Primatologists, a Fellow of the California Academy of Sciences, and a Fellow of the American Association for the Advancement of Science.

Research Focus

Professor Isbell’s overarching research interests are largely focused on primate socioecology, and she will study any topic that helps her understand more fully the ecological conditions that have influenced primate social organizations. These include all aspects of food (e.g., competition, spatial and temporal distribution, abundance, and nutrition), predation, dispersal, and ranging behavior. She is field-oriented, and has engaged in multi-year fieldwork in Uganda and Kenya, with briefer forays into Madagascar, Tanzania, Rwanda, the Democratic Republic of Congo, and India. She is no longer accepting graduate studets.
