What we do:


We have research projects in several areas related to RNA viruses, pathogenesis, viral evolution, viral population dynamics, host barriers, vaccines, and antiviral treatment response. Our overall

goal is to understand virus-host interactions and antiviral drug responses that impact the development of disease. For more details, see our research page.


  1. 1.Poliovirus and yellow fever virus population dynamics during trafficking in an infected host, and identification of host barriers that limit viral spread.

  2. 2.Neurotropic virus trafficking barriers.

  3. 3.The effect of the gut microbiota on enteric virus replication, shedding, and pathogenesis.

  4. 4.Host-based ribavirin resistance in cultured cells and hepatitis C virus patients.
