Profile Headshot


Joan A. Casey received her doctoral degree from the Department of Environmental Health Sciences at Johns Hopkins Bloomberg School of Public Health in 2014. Dr. Casey is an environmental epidemiologist who focuses on environmental health, environmental justice, and sustainability. Her research uses electronic health records and spatial statistics to study the relationship between emerging environmental exposures and population health. She also considers vulnerable populations and the implications of health disparities, particularly in an era of climate change. Dr. Casey investigates a range of exposures including unconventional natural gas and oil development, coal-fired power plants, wildfires, power outages, and concentrated animal feeding operations. She also teaches in the MPH Core. Dr. Casey also holds a BS in Biological and Environmental Engineering from Cornell University and an MA in Applied Physiology from Teachers College at Columbia University.
