at the Pacific Northwest National Laboratory for 6 years and then as a senior lecturer in the Department of Environmental Engineering at the University of Western Australia for 3 years. His research interests are in modeling of water flow and reactive-contaminant transport in groundwater systems, bioremediation of contaminated aquifers, numerical modeling of environmental processes, water-quality modeling, and optimal design of treatment systems. He is a member of the Groundwater Quality Committee of the American Society of Civil Engineers (ASCE) and served as the associate editor of ASCE’s Journal of Hydrologic Engineering and the Journal of Contaminant Hydrology. Dr. Clement received his MSc in physics from Madurai University, his MTech in environmental sciences and engineering from the Indian Institute of Technology, Bombay, and his PhD in civil engineering from Auburn University. He is a registered professional civil engineer.
Carole A. Kimmel is a consultant in toxicology and risk assessment, particularly in reproductive and developmental effects. She was a senior scientist for 20 years with the National Center for Environmental Assessment at the U.S, Environmental Protection Agency (EPA). She spent her career at EPA working on advances in risk assessment for noncancer health effects, including reproductive and developmental toxicity and neurotoxicity. Dr. Kimmel cochaired the Developmental Disorders Working Group of the President’s Task Force on Environmental Health Risks and Safety Risks to Children and was a leader in an interagency effort to plan and implement the National Children’s Study. She is a former president of the Teratology Society and of the Reproductive and Developmental Toxicology Specialty Section of the Society of Toxicology. Her current consulting work includes a part-time position with Exponent as a senior managing scientist and continued involvement in the National Children’s Study. Dr. Kimmel received her PhD in anatomy and teratology from the University of Cincinnati.
Francine Laden is an assistant professor of environmental epidemiology at the Harvard School of Public Health and assistant professor of medicine at the Channing Laboratory of Brigham and Women’s Hospital and Harvard Medical School. Her research interests are in the environmental epidemiology of cancer and respiratory disease. Her current research is focused on analyses of the relationship between organochlorines and non-Hodgkin lymphoma and Parkinson disease; lung cancer and cardiovascular mortality and diesel exhaust in the Trucking Industry Particle Study; ambient air pollution and cardiopulmonary disease in the Nurses’ Health Study; and mortality followup in the Harvard Six Cities Study. Dr. Laden was a member of the Institute of Medicine Committee on Gulf War and Health: Review of the Medical Literature Relative to Gulf War Veterans’ Health. She received her MS in environmental health management and her ScD in epidemiology from the Harvard School of Public Health.
Bruce P. Lanphear is a senior scientist at the Child & Family Research Institute and professor of Children's Environmental Health at Simon Fraser University, both in British Columbia, Canada. He is the principal investigator for a study of fetal and early-childhood exposure to prevalent environmental neurotoxins—including lead, alcohol, pesticides, mercury, polychlorinated biphenyls, and environmental tobacco smoke—funded by the National Institute of Environmental Health Sciences and the Environmental Protection Agency (EPA). Dr. Lanphear has conducted numerous epidemiologic studies and randomized controlled trials of environmental hazards, including the use of high-efficiency particulate air cleaners to reduce asthma symptoms and lead-hazard controls to prevent childhood lead exposure. His research also explores gene-environment interactions to enhance understanding of susceptibility to environmental pollutants. He recently served on EPA’s Clean Air Scientific Advisory Committee for the national ambient air quality lead standard. He received his MD from the University of Missouri-Kansas City, and his MPH from the Tulane University School of Public Health and Tropical Medicine.
Xiaomei Ma is an assistant professor in the Department of Epidemiology of the Yale School of Public Health. Her research interests are in the epidemiology of malignancies of the human hematopoietic system. Specifically, she is interested in environmental and genetic factors in the etiology of childhood leukemia, the epidemiology of myeloproliferative disorders, and methodologic issues in the design of epi-
