Our research is focused on three main areas:

1. The molecular dynamics and biological significance of virus-host interactions during late stages of RNA virus assembly and egress.

2. The identification and development of host-oriented therapeutics as a new class of antiviral inhibitors.

3. The interplay between the host innate immune response and RNA virus infection.

Our model virus systems to interrogate these topics include:

Filoviruses (Ebola and Marburg viruses)
Arenaviruses (Lassa fever and Junín viruses)
Rhabdoviruses (VSV)
Retroviruses (HIV-1 and HTLV-1)
