PROF. TYRONE B. HAYES (born July 29, 1967) Professor of Integrative Biology, Museum of Vertebrate Zoology, Endocrinology, Molecular Toxicology and the Energy and Resources Group. Tyrone B. Hayes was born and raised in Columbia, South Carolina where he developed his love for biology. He received his Bachelor's degree from Harvard University in 1989 and his PhD from the Department of Integrative Biology at the University of Califonia, Berkeley in 1993. After completing his PhD, he begun pst-doctoral training at the National Institute of Child Health and Human Development, National Institutes of Health and the Cancer Research Laboratories at UC Berkely (funded by the National Science Foundation), but this training was truncated when he was hired a a Assistant Ptofessor at UC Berkeley in 1994. He was promoted to Associate Professor with tenure in 2000 and to full professor in 2003. Hayes' research focuces in developmental endocrinology with an emphasis on evolution and enviromental regulation of growth and development. For the last twenty years, the role of endocrine disrupting contaminants, particulary pesticides has been a major focus. Hayes is interested in the impact of chemical contaminats on environmental health and public health, with a specific interest in the role of pesticides in global amphibian declines and environmental justice concerns associated with targeted exposure of recial and ethnic minorities to endocrine disputors and the role that exposure plays in health care disparities
