Specialization

Virophysics: use of physical models to resolve the temporal and spatial dynamics of viral infections. Specifically, the development of realistic mathematical and computer models to capture and expalin the kinetics of virus infection spread within a cell culture (in vitro) or a host (in vivo). Apply physical models to accurately quantify the mode of action and efficacy of antiviral drugs and the phenotypic effect of virus mutations which confer drug resistance. Virus of primary interest: influenza, hepatitis C, dengue, and the respiratory syncitial virus.
