I am interested in public health disparities between high and low income nations related to water. My dissertation research focuses on the transmission of Helicobacter pylori in the drinking water supply in Lima, Peru.

• Population sciences: Measuring the quantities of H. pylori in drinking water to which populations in Lima, Peru are exposed.

• Laboratory sciences: In the laboratory, performing dosing experiments to more accurately estimate the infectious dose of H. pylori in drinking water and evaluating whether traditional household water treatment systems are able to prevent transmission of H. pylori in water.

• Mathematical modeling: Using mathematical modeling approaches, quantifying the risk of infection from waterborne H. pylori and examining whether household water treatment systems can mitigate that risk.
