Professor Doug Dockery, MS, ScD, is Professor of Environmental Epidemiology and Chairman of the Department of Environmental Health at Harvard School of Public Health. Professor Dockery is internationally known for his innovative work in environmental epidemiology, particularly in understanding the relationship between air pollution and respiratory and cardiovascular mortality and morbidity. He was one of the principal investigators of the landmark Six Cities Study of Air Pollution and Health, which showed that people living in communities with higher fine particulate air pollution had shorter life expectancies. Dr. Dockery is currently evaluating the benefits of improved air quality on people’s health. He has been mentor to some of the outstanding investigators in environmental epidemiology including Bert Brunekreef, Annette Peters, Arden Pope, and Joel Schwartz. The International Society for Environmental Epidemiology honored him with its first award for Outstanding Contributions to Environmental Epidemiology in 1999 and the first Best Paper in Environmental Epidemiology Award in 2010.
