About Me

I am currently an Associate Research Scientist working with Prof. Jeffrey Shaman in the Department of Environmental Health Sciences at Mailman School of Public Health, Columbia University. I am interested in mathematical modeling, statistical inference and real-time forecast of infectious disease spread. I study the transmission dynamics of seasonal and emerging infectious diseases at both population and individual levels. Using dynamical models informed by empirical data, my recent work involves the development of real-time forecast systems to predict the spatial spread of influenza and dengue, as well as statistical methods to infer nosocomial transmission and asymptomatic carriage of antibiotic-resistant bacteria. In addition, I investigate how the nonlinear model dynamics can be harnessed to improve disease surveillance and forecast.
