Bumsuk Hahm, PhD


Our research is focused on investigating the mechanisms of RNA virus-host interaction, viral regulation of host immunity, and viral pathogenesis. We create and utilize small-animal models and tissue culture systems for infection with RNA viruses such as influenza virus and lymphocytic choriomeningitis virus (LCMV). Our study should assist in the development of novel therapies including anti-viral drugs and immune therapeutics to remedy diseases caused by viral infections.
