Sverre Vedal, MD, MSc

Professor, Env. and Occ. Health Sciences (Primary department)
Adjunct Professor, General Internal Medicine
Dr. Vedal received his MD from the University of Colorado in 1976. He completed an internal medicine residency from 1976 to 1979 at the University of Rochester and a clinical pulmonary fellowship from 1979 to 1981 at the University of Utah. He is board certified in Internal Medicine and Pulmonary Medicine. Following clinical training, he did a research fellowship in respiratory epidemiology at the Channing Laboratory of Harvard Medical School from 1981 to 1983 and received an MSc in epidemiology in 1983 from the Harvard School of Public Health. Dr. Vedal was a faculty member in the Respiratory Division at the University of British Columbia from 1983 to 2001 and in the Division of Environmental and Occupational Health Sciences at National Jewish Health in Denver, Colorado from 2001 to 2004. He joined the faculty of the University of Washington in 2004 as Professor in Environmental and Occupational Health Sciences in the School of Public Health where he teaches courses to undergraduate and graduate students. Dr. Vedal directs the Center for Clean Air Research (CCAR) at the University of Washington, a multi-institutional center funded by the US Environmental Protection Agency (EPA) that is employing the disciplines of exposure science, toxicology, epidemiology and biostatistics to investigate the multi-pollutant cardiovascular health effects of exposure to traffic pollution. Other currently funded research projects focus on the cardiovascular effects of exposure to specific sources and chemical components of ambient air pollution and the role of genetic polymorphisms in modifying these effects. He maintains an interest in occupational and environmental lung disease and sees patients in the Occupational and Environmental Medicine Clinic at Harborview Medical Center. Dr. Vedal served as a member of the EPA Clean Air Scientific Advisory Committee (CASAC) from 1997 to 2003 and continues as a member of CASAC panels for particulate matter and ozone. He serves currently as a member of the NIH Infectious, Reproductive, Asthma and Pulmonary Conditions (IRAP) Study Section.

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.

Integrated epidemiologic and toxicologic cardiovascular studies to identify toxic components and sources of fine particulate matter
Funding Agency: Health Effects Institute (4749-RFA05)
The major goal of this project is to identify the compositional features of ambient particulate air pollution that determine cardiovascular health effects of long-term exposure to ambient particulate matter.

Cardiovascular disease and traffic in a multi-ethnic cohort: gene effects (a project of the DISCOVER Center - Cardiovascular disease and traffic-related air pollution)
Funding Agency: NIH/NIEHS (P50 ES015915)
The aim of this project is to use a gene-environment interaction approach to gain insight into mechanisms by which exposure to sources and components of ambient particulate matter cause cardiovascular disease.
