tection Agency (EPA) Particulate Matter Center and chair of the Health Effects Institute’s Research Committee. He has served as chair of EPA’s Environmental Health Committee and on the Executive Committee of the EPA Science Advisory Board. He is a former recipient of the National Institute of Environmental Health Sciences Academic Award in Environmental and Occupational Medicine. Dr. Utell is currently a member of the National Research Council’s Board on Environmental Studies and Toxicology. He previously served on the National Research Council Committee on Research Priorities for Airborne Particulate Matter, the Institute of Medicine (IOM) Committee to Review the Health Consequences of Service during the Persian Gulf War, and the IOM Committee on Biodefense Analysis and Countermeasures. He received his MD from Tufts University School of Medicine.
David B. Warheit received his PhD in physiology from Wayne State University School of Medicine in Detroit. Later, he received a National Institutes of Health (NIH) postdoctoral fellowship, and 2 years later, a Parker Francis Pulmonary Fellowship, both of which he took to the National Institute of Environmental Health Sciences to study mechanisms of asbestos-related lung disease with Arnold Brody. In 1984, he moved to the DuPont Haskell Laboratory to develop a pulmonary-toxicology research laboratory. His major research interests are pulmonary toxicity mechanisms and corresponding risks related to inhaled particles, fibers, and nanomaterials. He is the author or coauthor of more than 100 publications and has been the recipient of the International Life Sciences Institute (ILSI) Kenneth Morgareidge Award (1993, Hannover, Germany) for contributions in toxicology by a young investigator and the Robert A. Scala Award and Lectureship in Toxicology (2000). He has also attained diplomate status of the Academy of Toxicological Sciences (2000) and the American Board of Toxicology (1988). He has served on NIH review committees (NIH Small Business Innovation Research and NIH Bioengineering) and has participated in working groups of the International Agency for Research on Cancer, the European Centre for Ecotoxicology and Toxicology of Chemicals, Organisation for Economic Co-operation and Development, the ILSI Risk Science Institute, the ILSI Health and Environmental Sciences Institute, and the National Research Council. He has served on several journal editorial boards, including Inhalation Toxicology and Toxicological Sciences (as the current associate editor), Particle and Fibre Toxicology, Toxicology Letters, and Nano Letters. He is the chairman of the European Centre for Ecotoxicology and Toxicology of Chemicals Task Force on Health and Environmental Safety of Nanomaterials, serves on the National Institute for Occupational Safety and Health Board of Scientific Counselors, and is interim vice-president of the Nanotoxicology Specialty Section.
Mark R. Wiesner serves as director of the Center for the Environmental Implications of Nanotechnology, headquartered at Duke University, where he holds the James L.
