B.A., Biology, University of California, Berkeley 1976
Ph.D., Evolutionary Biology, University of Chicago 1982



Research Interests

Evolutionary biology, ecology and conservation biology of amphibians and reptiles. Recent research projects include comparative phylogeography of amphibians and reptiles in California and the central U.S., systematics of freshwater turtles and tortoises in Australia, California, and the rest of the globe, and conservation genetics of endangered California amphibians and reptiles. Recently, we have focused a great deal of ecological and genetical work on the California tiger salamander, an endangered species native to central California grassland habitat.

In addition to my appointment in the Department of Ecology and Evolutionary Biology, I am also the Director of the La Kretz Center for California Conservation Science http://www.environment.ucla.edu/lakretz/, a part of the UCLA Institute of the Environment and Sustainability (IoES) http://www.environment.ucla.edu/.
