PhD in Integrative Biology at the University of California, Berkeley
University of California, Berkeley
Dr. Tyrone B. Hayes's work is transforming biology one battle at a time. From a very early age, Tyrone knew that he was interested in biology, amphibians in particular. Always fascinated by frogs & toads, this facination has turned into a reality and a career. Dr. Hayes's work paves the way for an integrative approach to understanding how an organism reacts to changes in its environment.
His work includes studies on how exogenous hormones & endocrine disruptors influence developing tadpoles. Recently his work has gained international recognition for results demonstrating how atrazine, a wildly used pesticide which is found in groundwater, local streams & ponds, has been shown to alter reproductive development in frogs even at extremely low levels. Beyond his integratice, conscientious & conservational work, Tyrone has acted as a role model to minorities wanting to enter science. He has won numerous teaching awards, conservation awards & recognition as a leader in the scientific community.
