Research Scientist / Center for Conservation and Evolutionary Genetics
I am interested in the behavioral ecology, genetics, and conservation of mammals, both terrestrial and marine. Since 1980, I have been most concerned with conservation biology, especially the genetic problems of small captive and wild populations and field studies of threatened and endangered mammals, including sea otters and San Joaquin kit foxes. My practical experience with the problems of a variety of endangered species has led to my interest in developing noninvasive techniques for studying these species as well as the development of decision-making tools and processes to achieve better policy and management decisions.
