Professor, Biostatistics
Director, Center for Occupational Biostatistics and Epidemiology
Education B.S., University of Pittsburgh, 1973
M.S.(Hyg), University of Pittsburgh, 1974
Ph.D., University of Pittsburgh, 1977 Research Interests Dr. Marsh directs occupational epidemiologic studies to explore the long-term health effects of employment in occupations such as jet engine manufacturing and pharmaceutical production and to workplace exposures to agents including formaldehyde, tungsten carbide/cobalt, acrylamide, acrylonitrile, chloroprene, arsenic, petrochemicals and man-made mineral fibers. In addition, he conducts environmental epidemiologic studies of communities exposed to industrial pollutants or to hazardous waste site materials and is involved in basic methodological research related to longitudinal data analysis and quantitative risk assessment. Dr. Marsh also directs programs of biostatistical support for the health outcome research and quality improvement areas of large health maintenance organizations, and for the occupational and environmental health areas of major corporations and corporate trade organizations.
