Briana N.C. Chronister studies how environmental exposures affect health across adolescence and young adulthood, with a focus on pesticide exposure in rural agricultural communities. As an environmental and spatial epidemiologist, her research is grounded in a GeoHealth framework, integrating interdisciplinary geospatial, machine learning, remote sensing and epidemiologic methods to investigate contaminant exposure pathways and their subsequent health risks. Her recent work integrates urinary pesticide biomarkers and geospatial measures of exposure such as residential proximity to greenhouse floriculture to better understand patterns of environmental exposure and their associations with cognitive performance, depression symptoms, anxiety symptoms, and endocrine disruption.
Before joining Bursky Public Health, Chronister was a postdoctoral scholar at the University of California, San Diego Herbert Wertheim School of Public Health and Human Longevity Science. She earned her PhD in Public Health from the San Diego State University–University of California San Diego Joint Doctoral Program, her master of science in global health from the University of Notre Dame, and her bachelor’s degree in biological sciences from the University of Notre Dame.
