Gabriella Meltzer is a postdoctoral research fellow in environmental health and epidemiology at Columbia University’s Mailman School of Public Health in the National Institute of Environmental Health Science-funded T32 combined training program. Her public health research interests broadly encompass how environmental exposures—ranging from natural hazards, technological disasters, biohazards, and industrial pollution—create and exacerbate health disparities at critical and sensitive periods of the life course, including infancy, childhood and adolescence, pregnancy, and old age. She uses a variety of methods to explore these issues, including quantitative data analysis, in-depth interviewing and qualitative data analysis, community-based participatory research, and geospatial analysis. Gabriella received her PhD in public health from NYU School of Global Public Health in 2022, where she was primarily affiliated with the Center for Public Health Disaster Science. Her dissertation examined the adverse consequences of child and adolescent exposure to the Deepwater Horizon oil spill in the context of cumulative environmental and family stress. Prior to her doctoral studies, Gabriella received her bachelor’s degree in Health and Societies from the University of Pennsylvania and was a global health research associate at the Council on Foreign Relations.
