Bio

Joan A. Casey (she/her) received her doctoral degree from the Department of Environmental Health Sciences at Johns Hopkins Bloomberg School of Public Health. Dr. Casey uses large secondary spatial data sources to investigate the health impacts of a range of emerging environmental exposures including wildfires, power outages, fossil fuel infrastructure, and the energy transition. She prioritizes the study of joint social and environmental risk factors that help explain persistent health disparities and focuses on policy-relevant climate justice work. 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.
