Mary B. Rice MD, MPH
Portrait of Dr. Rice
Dr. Rice is a pulmonary critical care physician and the Director of the BIDMC Institute for Lung Health and an Assistant Professor of Medicine at Harvard Medical School. Her area of investigation focuses on the influence of environmental exposures, especially air pollution, on the respiratory health of children and adults.  She is developing new applications for portable monitoring technology and non-invasive sampling of the upper respiratory tract to improve our understanding of how indoor exposures affect respiratory symptoms, and how indoor air quality can be improved for lung health.  She is the chair of the American Thoracic Society’s Environmental Health Policy Committee and co-chair of the Environmental Sustainability Committee of BIDMC.  She was the 2016 recipient of the David Bates American Thoracic Society award for her contributions to the field of environmental, occupational and population health.
