My research interests are to understand the molecular mechanisms underlying virus-host interactions, focusing on the mechanisms underlying viral immune evasion that contribute to virus virulence and disease pathogenesis. My goal in studying virus-host interactions is to translate the basic knowledge generated with this research into improved vaccines and/or vaccine vectors for disease prevention and control. Other applied virology research interests include: (i) diagnostic assay development and (ii) livestock feed biosecurity.
