Jeffrey D. Wolt is professor of agronomy and toxicology at Iowa State University and adjunct professor of epidemiology at the University of Iowa. His research interests are in pesticide and biotechnology safety analysis applied to risk management and science policy decision making, soil and environmental chemistry applied to exposure assessment, environmental monitoring, and environmental toxicology. Outreach responsibilities center on risk communication and harmonization of formalized frameworks for risk management and public policy decision making. Before joining the university in 2004, Dr. Wolt was an environmental chemist and risk analyst in industry where he served as co-chair of the Federal Insecticide, Fungicide, and Rodenticide Act Environmental Model Validation Task Force. He received his MS in agronomy and soil science and his PhD in soil chemistry from Auburn University.
Dr. Roberta L. Grant
Texas Commission on Environmental Quality
Roberta L. Grant is manger of the Toxicology Section at the Texas Commission on Environmental Quality (TCEQ), where she manages staff conducting toxicologic evaluations of air permit applications, monitoring projects, and risk assessments. She was involved in writing TCEQ?s guidelines for developing toxicity factors. She coordinates and is involved in the development of chemical-specific technical support documents to support the development of acute and chronic inhalation toxicity factors. Dr. Grant is also an adjunct professor in the College of Pharmacy at the University of Texas at Austin, where she teaches regulatory risk assessment. She was a member of the US Environmental Protection Agency?s National Advisory Committee for Review of Acute Exposure Guideline Levels, and has served on several of the agency?s Federal Insecticide, Fungicide, and Rodenticide Act scientific advisory panels. She received her PhD in toxicology from the University of Texas at Austin.
Dr. Matthew C. Keifer
Marshfield Clinic Research Foundation
Matthew C. Keifer is director of the National Farm Medicine Center. Before joining the center, he was associate director of the Pacific Northwest Agricultural Safety and Health Center at the University of Washington. His research and practice emphasize pesticide health effects and agricultural injury. He currently serves as the co-director of the Upper Midwest Agricultural Safety and Health Center, which is funded by the National Institute for Occupational Safety and Health. Dr. Keifer is a member of the US Environmental Protection Agency?s Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel. He was a member of the National Research Council?s Subcommittee for the Review of the Risk Assessment of Methyl Bromide, and the Institute of Medicine?s Committee on Occupational Information and Electronic Health Records. He received his MD in occupational medicine from the University of Illinois and his MPH in public health from the University of Washington.
Dr. Joseph V. Rodricks
Joseph V. Rodricks is a founding principal of ENVIRON International Corporation. His expertise is in toxicology and risk analysis and their uses in regulation. He was formerly deputy associate commissioner for health affairs and toxicologist for the US Food and Drug Administration. His experience includes chemical products and contaminants in food, food ingredients, air and water pollution, hazardous wastes, the workplace, consumer products, and medical devices and pharmaceutical products. Dr. Rodricks has served on over 30 committees of the National Research Council and the Institute of Medicine, including the Committee on Improving Risk Analysis Approaches Used by the US Environmental Protection Agency. In recognition of his extraordinary contributions these programs, he was designated a National Associate of the National Academy of Sciences. He received his PhD in biochemistry from the University of Maryland, and is a diplomate of the American Board of Toxicology.
Dr. Brenda Eskenazi
University of California, Berkeley
Brenda Eskenazi is professor of epidemiology at the University of California at Berkeley School of Public Health. She is also director of the Children?s Center for Environmental Health, and is chair of Community Health and Human Development. Her research interests are in the effects of environmental exposures (such as pesticides, lead, solvents, dioxin, and tobacco smoke) on reproductive, perinatal, and children?s health. Dr. Eskenazi was a member of the Institute of Medicine?s Board on Children, Youth and Families. She received her MA in psychology from Queens College and her PhD in neuropsychology from the City University of New York.
Dr. Robert M. Hollingworth
Michigan State University
Robert M. Hollingworth is professor emeritus in the Department of Entomology and the Center for Integrative Toxicology at Michigan State University. His research interests are in pesticide toxicology and toxic mechanisms and resistance mechanisms to pesticides. He is director of the North Central Region IR-4 Program, which is a 12-state program funded by the US Department of Agriculture that provides data to enable the registration of pesticides on specialty crops with the US Environmental Protection Agency. He also continues teaching activities on the risk assessment and regulation of chemical contaminants in the diet and the safety of genetically modified foods. Dr. Hollingworth received his PhD in insecticide toxicology from the University of California at Riverside.
Dr. Chengsheng (Alex) Lu
Harvard University School of Public Health
Chensheng (Alex) Lu is associate professor of environmental exposure biology at the Harvard School of Public Health. His research interests are in the use of biomarkers for assessing human exposures to environmental chemicals to facilitate the identification of risk factors. Current work involves projects to integrate exposure, metabolomics, and cumulative risk assessment tools for quantifying children?s longitudinal exposure to pesticides from dietary intakes. One of the current research projects is to identify biomarkers in the gene-environment paradigm in relation to pesticide exposure. He is also collaborating on studies with the Boston Housing Authority to minimize children?s residential exposures to pesticides in low-income urban public housing dwellings. Dr. Lu is a member the US Environmental Protection Agency?s Federal Insecticide, Fungicide, and Rodenticide Act Science Advisory Panel, and its food Quality Protection Act Science Review Board. He received his MS in environmental sciences from Rutgers University, and his PhD in environmental and occupational health sciences at the University of Washington.
