Dr. Gilbert has served as the Director of the Arkansas Center for Environmental Exposure Research (ACEER) since its inception in 2002. Dr. Gilbert has served on several advisory panels for the EPA and the National Toxicology Program concerning the impact of chlorinated solvents as triggers of autoimmune disease and other types of toxicity. Her broad-based expertise is underlined by the fact that she has also served on NIH review panels for Digestive, Kidney and Urological Systems; Immunology; and Infectious Disease and Microbiology. Her environmental research has focused on how chronic exposure to low concentrations of immunotoxicants such as chlorinated solvents (e.g. trichloroethylene) or heavy metals can trigger autoimmune diseases.

  • Dr. John C. Kissel
    University of Washington

    Dr. Kissel is Professor of Environmental and Occupational Health Sciences at the University of Washington in Seattle, where he has been a member of the faculty since 1990. He held a prior position in the School of Public and Environmental Affairs at Indiana University. Dr. Kissel holds a Ph.D. in Civil/Environmental Engineering from Stanford University, an S.M. in Environmental Engineering from Harvard University, and a B.S. in Civil Engineering from the University of Notre Dame. He is a registered Professional Engineer. Dr. Kissel's research interests generally involve human exposure assessment, with emphasis on exposures related to waste management, agricultural and residential use of pesticides, and consumer products. He is particularly interested in probabilistic prediction of aggregate exposure and reconciliation of model predictions with observed biomarker data. Dr. Kissel is a former President of the International Society of Exposure Science and also served one term as chair of the Exposure Assessment Specialty Group within the Society for Risk Analysis.

  • Dr. Bruce Perrin Lanphear
    Simon Fraser University 

    Bruce Lanphear, M.D., M.P.H., has published over thirty epidemiologic studies examining the relationship of environmental toxicants with intellectual delay, psychopathology, brain function, asthma and other health endpoints in children and young adults. These studies, which include both longitudinal and cross-sectional studies, tested the linkage of exposures to lead, PBDEs, tobacco or bisphenol A with IQ deficits, executive functions and ADHD in children. He has also conducted 7 community-based, randomized, controlled trials to test the efficacy of reducing environmental hazards on dust lead levels, children's lead concentrations, injuries, asthma symptoms or behavioral problems. He has been at the forefront of testing and validating the use of biomarkers of internal dose of environmental toxicants in birth cohorts -- including meconium, hair, urine, blood and serum -- and linking these biomarkers with neurobehavioral functions and other health endpoints in children.

  • Dr. Jaymie R. Meliker
    Stony Brook University

    Jaymie Meliker, Ph.D., is an academic scholar in the fields of exposure science and environmental epidemiology. His scholarship falls into two lines of inquiry: (1) identifying environmental factors that play important roles in disease morbidity, and (2) developing space-time methods that improve our ability to investigate exposure-disease relationships. Highlights of his work include pioneering development of space-time information systems for lifetime exposure reconstruction, and epidemiology of low-level exposure to arsenic in drinking water. He is an Associate Professor in the Program in Public Health, Department of Family, Population, and Preventive Medicine, Stony Brook University on Long Island, New York. He served as an elected councilor of the International Society of Exposure Science and was on the International Organizing Committee for the 2013 Annual Meeting in Basel, Switzerland.
