Sverre Vedal, MD, MSc

Professor, Env. and Occ. Health Sciences (Primary department)
Adjunct Professor, Medicine
Sverre Vedal is Professor in the Department of Environmental and Occupational Health Sciences at the University of Washington (UW) School of Public Health. He is a pulmonary physician and an epidemiologist with research interests in the adverse health effects of community air pollution and in occupational lung disease. He received his MD from the University of Colorado and MSc in epidemiology from Harvard University. Dr. Vedal directs the US Environmental Protection Agency (EPA) Center for Clean Air Research at the University of Washington that employs the disciplines of exposure science, toxicology, epidemiology and biostatistics to investigate the cardiovascular health effects of exposure to multi-pollutant atmospheres. He has published widely on air pollution exposure and health effects and served on advisory committees of the US EPA and the National Institutes of Health. Dr. Vedal teaches courses in the UW School of Public Health, sees patients in the Occupational and Environmental Medicine Clinic at Harborview Medical Center in Seattle and supervises clinical trainees and graduate student research. He currently holds the AXA Research Fund Chair in Air Pollution and Health at the Chinese Research Academy of Environmental Sciences in Beijing, China and spends 3 to 4 months each year working with Chinese collaborators on air pollution exposure and health studies in China.

University of Washington Center for Clean Air Research (CCAR)
Funding Agency: EPA (RD-83479601 / EPA-RC2009-STAR-C1)

This is a center project involving several institutions and projects examining how pollution from roadways affects cardiovascular health. The research integrates the fields of exposure science, epidemiology, toxicology, clinical studies, and biostatistics to study the cardiovascular hazards of recent and aged roadway emissions.

AXA Distinguished Successional Chair in Air Pollution and Health
Funding Agency: AXA Research Fund

This AXA chair is administered through the Chinese Research Academy of Environmental Sciences (CRAES) in Beijing, China. The goal is to promote collaboration between the chairholder and investigators and students at CRAES and elsewhere in China in investigating the health impacts of air pollution exposure in China.
