Personal Statement

Dr. Marsh designs and 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 occupational and environmental health areas of major corporations and corporate trade organizations. (Health Sciences Faculty Research Interests Project). Dr. Marsh is also developer and principal investigator of the software package OCMAP (Occupational Cohort Mortality Analysis Program), now licensed by the Office of Technology Management of UPitt, and the MPDS (Mortality and Population Data System) project.
