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.


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.

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.

He directs the National Pesticide Information Center, a cooperative agreement between OSU and the US Environmental Protection Agency. He also holds an appointment in Extension Services, where he engages diverse stakeholders on issues related to pesticide exposure, integrated pest management, risk assessment, and risk communication. Dr. Stone has served on several state and national scientific advisory panels, and is the past president of the Pacific Northwest Association of Toxicologists. In addition, he teaches courses on toxicology and biotechnology, is a co-leader in the Research Translation Core of OSU?s Superfund Program and an investigator on a Multicultural Scholars Program for under-represented students. Prior to joining OSU, Dr. Stone served as a state toxicologist for the Oregon Health Division. He received his MS from the University of North Texas and PhD in toxicology from Oregon State University.


Dr. Joseph V. Rodricks
ENVIRON

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. 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.
