addition to her extensive program management experience, Dr. Whittaker has extensive technical experience in hazard identification and noncancer and cancer dose-response assessment, including quantitative risk assessment (e.g., benchmark dose modeling for both carcinogens and noncarcinogens). She has worked at two of the country’s leading toxicology and risk assessment consulting firms (the ENVIRON Corporation and the Weinberg Group). Dr. Whittaker has over a decade of experience evaluating health hazards and quantitating human health risks for low-level contaminants in drinking water, pharmaceuticals, medical devices, cosmetics, and food additives. She is a Diplomat of the American Board of Toxicology (D.A.B.T.). Dr. Whittaker earned a Ph.D. in toxicology from the University of Maryland, Baltimore, and an M.P.H. in environmental health from the University of Michigan.

Dale Whittington is professor of environmental sciences and engineering, city and regional planning, and public policy at the University of North Carolina, Chapel Hill. Since 1986, he has worked for the World Bank and other international agencies on the development and application of techniques for estimating the economic value of environmental resources in developing countries, with a particular focus on water and sanitation and vaccine policy issues. Dr. Whittington has published extensively on cost-benefit analysis, environmental economics, and water resources planning and policy in developing countries. His current research interests include the development of planning approaches and methods for the design of improved water and sanitation systems for the rapidly growing cities of Asia. Dr. Whittington received his A.B. at Brown University, his M.P.A. at the University of Texas, his M.Sc. at the London School of Economics and Political Science, and his Ph.D. at the University of Texas.
