Research

My research focuses on human-environmental interactions as they relate to diseases and ill-health. I am particularly interested in infectious diseases in Asia, and how environmental alteration and population migration act as drivers of disease ecologies. My master’s work considered the impact of flood protection on cholera incidence in Matlab, Bangladesh. My doctoral work is examining population-environment drivers of H5N1 influenza viral evolution in Vietnam and China.
