Dr. Jenna R. Krall is an assistant professor in the Department of Global and Community Health. Krall is a biostatistician with research interests in air pollution and environmental epidemiology. Her work has been focused on developing methods for estimating sources of air pollution and their associations with health. She is also interested in statistical computing (R, SAS, Stata) and collaborative work related to chemical mixtures, spatial statistics, and missing data. She received her PhD in biostatistics from the Johns Hopkins Bloomberg School of Public Health and her BA from George Mason University. Prior to joining GCH, Krall completed a postdoctoral fellowship in the Department of Biostatistics and Bioinformatics at Emory University. Please see her research website for more information.
