Profile Headshot


Anne (Annie) Nigra is an environmental health scientist (PhD, Columbia University Mailman School of Public Health '20) and environmental epidemiologist (ScM, Johns Hopkins Bloomberg School of Public Health '16). Dr. Nigra's long-term scientific goal is to reduce racial/ethnic and socioeconomic inequities in environmental exposures and related adverse health outcomes. To this end, her work evaluates regulatory policies, characterizes inequities in exposures, develops epidemiological effect estimates, and supports community-directed research and training efforts. Her research focuses on US drinking water regulations and exposures, metal exposures, metal-related chronic disease, and environmental justice, and utilizes collaborations with several large epidemiological cohorts. She also has an emerging research interest in adverse birth outcomes, and manages the Columbia University Drinking Water Dashboard ( Dr. Nigra also holds a BA in Biology from Oberlin College ('14).
