I am an Assistant Professor in the Department of Emergency Medicine at Johns Hopkins University. I am also a fellow at the Center for Disease Dynamics, Economics & Policy in Washington, DC. My research focuses on the role of individuals in the spread of infectious diseases, which sits at the nexus of economics, epidemiology and public policy, and is premised on the idea of incorporating incentives for healthy behavior and their attendant behavioral responses into an epidemiological context to better understand how diseases are transmitted. The vast majority of my research has been on the emergence and spread of antimicrobial drug resistance, focusing in particular on antibiotics and anti-malarial drugs. My research is about evenly split between developing an understanding for the factors that drive resistance through epidemiological studies using large national databases of hospitalization and antibiotic use, and developing an understanding of the underlying ecology and epidemiology (and how this is impacted by human behavior) using models.
