Tyrone B. Hayes (Sept. 14, 9 a.m.)
Tyrone B. Hayes is an American biologist and professor of integrative biology at the University of California, Berkeley who is known for his research findings concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes and feminizes male frogs. He is also an advocate for critical review and regulation of pesticides and other chemicals that may cause adverse health effects. Hayes has presented hundreds of papers, talks and seminars on his conclusions that environmental chemical contaminants have played a role in global amphibian declines and in the health disparities that occur in minority and low-income populations. His work has been contested by Syngenta, the Swiss manufacturer of atrazine, and the Australian Pesticides and Veterinary Medicines Authority and was used as the basis for the settlement of a multimillion-dollar class action lawsuit against Syngenta.
Dr. James Carrington (Sept. 15, 9 a.m.)
Dr. James Carrington is internationally recognized for his research on gene silencing, the functions of small RNA and virus-host interactions. His work in the small RNA field has focused on mechanisms through which plants and other organisms use noncoding RNA to control growth and development and defend against viruses. Carrington’s awards include the Presidential Young Investigator Award from the National Science Foundation, the Ruth Allen Award from the American Phytopathological Society and the Humboldt Research Award from the Alexander von Humboldt Foundation. He was elected as a member of the National Academy of Sciences in 2008 and is a Fellow of the American Academy of Microbiology, the American Phytopathological Society and the American Association for the Advancement of Science. Prior to joining the Danforth Center, Carrington served as the director of the Center for Genome Research and Biocomputing, the Stewart Professor for Gene Research and Distinguished Professor of Botany and Plant Pathology at Oregon State University. He received his bachelor’s degree in plant science from the University of California, Riverside and doctorate in plant pathology from the University of California, Berkeley.
