Dr. Tyrone Hayes’ research focuses on the role of steroid hormones in amphibian development,
with particular emphasis on metamorphosis and sex differentiation. He is well known for his
work on the effects of atrazine on the feminization of amphibians. This pioneering work brought Dr. Hayes to the center of controversy between academia, industry, and regulatory agencies. As a result, he has a unique perspective into the politics of environmental science and the conduit between scientific data and policy. Dr. Hayes maintains an active and rigorous undergraduate
research laboratory at the University of California, Berkeley. His work has been profiled by many news agencies, including National Geographic, Discover Magazine, and National Public Radio.
