Annie Nigra is an environmental health scientist and environmental epidemiologist. She is currently a Postdoctoral Research Fellow working with Professor Ana Navas-Acien in the Department of Environmental Health Sciences at the Mailman School of Public Health. Her work focuses on understanding the relationship between metal exposures (arsenic, mercury, lead, etc.) and related chronic disease, and on assessing population-level metal exposures using both biological and environmental monitoring. She focuses on projects that evaluate federal regulations intended to reduce metal exposures and related adverse health outcomes, are community- owned/directed/managed, or assess environmental injustices and aim to eliminate exposure and health disparities. Annie received her PhD in Environmental Health Sciences from the Columbia University Mailman School of Public Health, a ScM in Epidemiology from Johns Hopkins School of Public Health, and a BA in Biology from Oberlin College.
