Andrea Baccarelli, Dean of the Faculty

Andrea BacarrelliAndrea Baccarelli, MD, PhD, is the Dean of the Faculty at the Harvard T.H. Chan School of Public Health.

A distinguished scientist, Dr. Baccarelli investigates the molecular mechanisms by which a wide array of environmental exposures causes human disease. He was elected to the National Academy of Medicine for his pioneering work showing that social and environmental risk factors adversely affect the human epigenome, thereby causing long-term health consequences. Beyond epigenomics, he has explored mechanisms including epitranscriptomics, extracellular vesicles, small non-coding RNAs, mitochondrial DNA, and the microbiome to understand the way toxins and other stressors affect genetic expression and overall health. Dr. Baccarelli’s work has been used by multiple agencies worldwide, including the U.S. Environmental Protection Agency, to help shape pollution control policies.

Before he took office as Dean of the Faculty in January 2024, Dr. Baccarelli served as the Leon Hess Professor and Chair of the Department of Environmental Health Sciences at Columbia Mailman School of Public Health. He also served as director of the NIH/NIEHS P30 Center for Environmental Health and Justice in Northern Manhattan and as president of the International Society for Environmental Epidemiology.

Dr. Baccarelli previously worked at Harvard Chan School as an associate professor from 2010 through 2016. He holds an MD from the University of Perugia in Italy, an MS in Epidemiology from the University of Turin, and a PhD from the University of Milan.
