Tyrone Hayes is the Judy Chandler Webb Distinguished Chair for Innovative Teaching and Research and a professor in the Department of Integrative Biology at UC Berkeley. His research focuses on the role of steroid hormones in amphibian development and he conducts both laboratory and field studies in the U.S. and Africa. The two main areas of interest are metamorphosis and sex differentiation, but he is also interested in growth (larval and adult) and hormonal regulation of aggressive behavior. His work addresses problems on several levels including ecological, organismal, and molecular questions.
