ticular injury. Current projects include the study of co-exposure synergy using model testicular toxicants and of the effects of in utero endocrine-disruptor exposure on steroidogenesis and a predisposition to cancer. Dr. Boekelheide serves on the National Research Council Standing Committee on Use of Emerging Science for Environmental Health Decisions and previously served on the Committee on Toxicity Testing and Assessment of Environmental Agents (which produced Toxicity Testing in the 21st Century), the Subcommittee on Fluoride in Drinking Water, and the Committee on Gender Differences in Susceptibility to Environmental Factors: A Priority Assessment. He is a councilor of the Society of Toxicology and a past member of the Board of Scientific Counselors of the National Toxicology Program (NTP) and has been a member of various expert panels (such as those on bisphenol A, phthalates, and bromopropanes) of the NTP Center for the Evaluation of Risks to Human Reproduction. Dr. Boekelheide received his MD and his PhD in pathology from Duke University and is board-certified in anatomic and clinical pathology.
John Bucher is associate director of the National Toxicology Program (NTP) of the National Institutes of Health’s National Institute of Environmental Health Sciences. His research interests include characterization of the toxic and carcinogenic potential of a variety of chemicals, mixtures, and physical agents of interest to the NTP, and issues related to the improvement of research tools and assays. As associate director of the NTP, Dr. Bucher is responsible for oversight of the NTP toxicology and carcinogenesis studies, of the NTP Report on Carcinogens, and of the NTP Center for the Evaluation of Risks to Human Reproduction and for administrative support for the Alternative Animal Assay Validation Program of the Interagency Coordinating Committee on the Validation of Alternative Methods. Newer efforts include the development of initiatives that examine the genetic basis of variations in response to environmental agents and implementation of new tools for toxicity testing as outlined in the NTP vision and roadmap for the future. Dr. Bucher earned a PhD in pharmacology from the University of Iowa and is a diplomate of the American Board of Toxicology.
George Daston is a Victor Mills Society Research Fellow at Procter & Gamble Company. He is also an adjunct professor in the Department of Pediatrics and the Developmental Biology Program of the University of Cincinnati. Dr. Daston’s current research efforts are in toxicogenomics and mechanistic toxicology, particularly in addressing how findings in these fields can improve risk assessment of chemicals. He has published over 100 peer-reviewed articles, reviews, and book chapters and has edited three books. His professional activities include serving as president of the Teratology Society, as a councilor of the Society of Toxicology, as a member of the U.S. Environmental Protection Agency (EPA) Board of Scientific Counselors, and as a member of the National Toxicology Program Board of Scientific Councilors. He is a member of the National Research Council (NRC) Standing Committee on Use of Emerging Science for Environmental Health Decisions and has served as a member of the Committee on Developmental Toxicology, the
