Research interests

My research interests are focused on the virus-host interactions in the replication and pathogenesis of two RNA viral pathogens, arenaviruses and influenza virus. (1) Arenaviruses such as Lassa fever virus can cause hemorrhagic fevers in humans with limited prophylactic and therapeutic treatments. We are interested in studying the replicative and pathogenic mechanisms of arenaviruses with a particular emphasis placed on the virus-host interactions during viral infections. For these studies, we use various molecular, cellular, and viral systems, as well as a safe and relevant small animal model for Lassa fever that is based on the Pichinde virus infection of guinea pigs. (2) Influenza virus causes acute respiratory disease that can lead to severe and deadly complications. Current vaccine program and existing antivirals are unable to provide complete preventative or therapeutic effects due to the constantly evolving nature of influenza virus resulting in vaccine escaped and drug-resistant virus variants. We are interested in studying the roles of host factors and signaling pathways in the influenza viral replication and disease pathogenesis in the lungs with an ultimate goal of developing novel antiviral therapeutics against influenza viral infection.

Current research projects include:
1. Virulence determinants and mechanisms of arenaviruses
2. Mechanisms of Arenavirus-induced immune suppression
3. Pathogenesis of arenavirus hemorrhagic fevers
4. Influenza virus interactions with host signaling pathways
5. Pathogenesis of influenza virus-induced lung inflammation
6. Antivirals and vaccines
