Jonathan Samet (born 1948) is an American epidemiologist and professor known for his extensive research on the health effects of air pollution, tobacco smoke, and other environmental risk factors. He has contributed significantly to the fields of environmental health, public health policy, and risk assessment.
Early Life and Education
- Born in 1948 in the United States.
- Earned a B.S. in Chemistry from the University of Michigan (1970).
- Received an M.D. from the University of Michigan Medical School (1974).
- Completed a residency in internal medicine and a fellowship in pulmonary disease and critical care at the University of California, San Francisco (UCSF).
- Obtained a Ph.D. in Epidemiology from the Johns Hopkins Bloomberg School of Public Health (1984).
Academic and Professional Career
- Joined the faculty of the University of Southern California (USC) Keck School of Medicine in 1990, where he serves as Professor of Pulmonary and Critical Care Medicine, Environmental Medicine, and Biostatistics.
- Holds the position of Director of the USC Center for Environmental Health Sciences.
- Served as President of the International Society for Environmental Epidemiology (ISEE) from 2009 to 2011.
- Has been a senior advisor to the U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO) on issues related to air quality and health risk assessment.
Research Contributions
- Pioneered epidemiologic studies linking ambient particulate matter (PM₂.₅) exposure to cardiovascular and respiratory morbidity and mortality.
- Conducted seminal work on the health impacts of secondhand smoke, contributing to policy and regulatory decisions worldwide.
- Developed methodological frameworks for causal inference in environmental epidemiology, including criteria for judging causality in environmental health research.
- Authored and co‑authored numerous peer‑reviewed articles, book chapters, and reports; his publications have been cited extensively in public health literature.
