Lianne Sheppard, PhD, MSc

Assistant Chair, Env. and Occ. Health Sciences
Professor, Env. and Occ. Health Sciences (Primary department)
Professor, Biostatistics
Dr. Sheppard is Professor and Assistant Chair of Environmental and Occupational Health Sciences and Professor of Biostatistics. She has a Ph.D. in biostatistics. Her interests center on observational study methods, epidemiology, and the health effects of occupational and environmental exposures. She is principal investigator of a NIH-funded training grant called Biostatistics, Epidemiologic & Bioinformatic Training in Environmental Health. She leads the biostatistical cores for several projects and collaborates with DEOHS faculty on air pollution cohort studies, identifying the effects of multipollutant exposures, and studying manganese exposures. She is a member of the Epidemiology editorial board, the Health Effects Institute Review Committee, several EPA Clean Air Scientific Advisory Committee Special Review Panels, and the EPA Scientific Advisory Board Chemical Assessment Advisory Committee Ethylene Oxide Review Panel.

Projects

Studies of air pollution exposures and their effects on health. These include MESA Air to assess the effect of long-term exposure to air pollution and the progression of subclinical atherosclerosis, the DISCOVER Center to study the mechanistic relationship between cardiovascular disease and traffic related air pollution, and the UW CCAR to study the cardiovascular health effects of near roadway pollution.

Statistical methods in environmental and occupational epidemiology.
