Dr. Sen Pei is interested in mathematical modeling, statistical inference and real-time forecast of infectious disease spread. With expertise in applied mathematics, statistics and network science, he studies the transmission dynamics of seasonal and emerging infectious diseases at both population and individual levels. Using dynamical models informed by empirical data, his 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, he investigates how the nonlinear model dynamics can be harnessed to improve disease surveillance and forecast.
