James J. Quackenboss

Title: Research Physical Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Measurements and Analysis Branch

James is a Research Physical Scientist, in the Exposure Measurements and Analysis Branch in the U.S. Environmental Protection Agency’s National Exposure Research Laboratory (NERL). He currently chairs the Interagency Coordinating Committee for the multi-agency National Children’s Study (NCS), and has worked with the NCS on exposure assessment designs and approaches. He chaired a joint committee to conduct a workshop on the sampling design for the NCS, and led the development of design options and background documents for consideration by the workshop panel and the NCS Advisory Committee. At EPA, he contributed to the development of the National Human Exposure Assessment Survey (NHEXAS), was the principal EPA collaborator for a NHEXAS pilot study, and coordinated the development of the Minnesota Children’s Pesticide Exposure Study. Prior to coming to EPA in 1991, he was involved in the application of exposure assessment techniques to epidemiological studies at the University of Arizona, and conducted personal exposure and indoor air quality studies at the University of Wisconsin.
