In addition to describing the effects of atrazine on reproductive development and function and the impacts on wildlife, Professor Hayes will discuss the manufacturer's repeated attempts to discredit his work, their personal attacks, and the EPA's role in keeping the herbicide on the market.
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 California, Berkeley in 1993. After completing his PhD, he began post-doctoral training at the National Institute of Child Health and Human Development, National Institutes of Health and the Cancer Research Laboratories at UC Berkeley (funded by the National Science Foundation), but this training was truncated when he was hired as an Assistant Professor at UC Berkeley in 1994. He was promoted to Associate Professor with tenure in 2000 and to full Professor in 2003. Hayes' research focuses on developmental endocrinology with an emphasis on evolution and environmental regulation of growth and development. For the last ten years, the role of endocrine disrupting contaminants, particularly pesticides, has been a major focus. Hayes is interested in the impact of chemical contaminants 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 racial and ethnic minorities to endocrine disruptors and the role that exposure plays in health care disparities.
