Ben Davis


Ben Davis is a 4th year PhD Candidate in the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health. His research interests include applying geostatistical methods to predict infectious microorganisms in water. Specifically he is modeling the presence and concentration of Vibrio parahaemolyticus in shellfish in the Chesapeake Bay. His experience in food safety, environmental epidemiology, remote sensing, risk assessment and science policy have prepared him to undertake this work and will continue to support him throughout this scientific career.
