Profile Headshot


Andrea Baccarelli, MD, PhD is the Leon Hess Professor and Chair of the Department of Environmental Health Sciences and serves as the Director of the NIH/NIEHS P30 Center for Environmental Health and Justice in Northern Manhattan, one of such 21 centers across the country. Dr. Baccarelli's work has supported international best practices for air pollution control developed by multiple agencies worldwide, and his findings have served as the basis for the Environmental Protection Agency's decision to enforce stricter guidelines for human exposure.

Dr. Baccarelli's research investigates molecular mechanisms as pathways linking environmental exposures to human disease. Current projects investigate a range of mechanisms, including epigenomics, epitranscriptomics, extracellular vesicles and small non-coding RNAs, mitochondrial DNA, and the microbiome.

Dr. Baccarelli was elected to the National Academy of Medicine for his pioneering work showing that environmental exposures adversely affect the human epigenome and has been included in the Web of Science list of highly cited, world's most influential scientists of the past decade.
