Broadly, I am interested in understanding how the interface of human behavior and the environment affect disease emergence and transmission of emerging and enteric infections, improving and standardizing surveillance systems for accurate burden monitoring, and identifying practical community-driven solutions for disease control. My current research focuses on exploring strategies for cholera control and elimination using spatiotemporal modeling and serological data, surveillance and control of SARS-CoV-2, and understanding the social and infrastructural components in the U.S. that contribute to the differential spread of COVID-19.
