Virology
Virus-host interactions and viral pathogenesis
Molecular/recombinant vaccines
Diagnostic virology

Area(s) of Research

My research focuses on the molecular mechanisms underlying virus-host interactions and vaccine development. We study the mechanisms underlying viral immune evasion that contribute to virus virulence and disease pathogenesis. My ultimate goal in studying virus-host interactions is to translate the basic knowledge generated with these studies into improved vaccines and/or vaccine vectores for infectious disease prevention and control.
