Research Interests

Research interests include molecular aspects of HIV-1 pathogenesis using the chimeric simian-human immunodeficiency virus (SHIV)/ macaque model system with specific interests in:

  • molecular mechanisms through which the Vpu protein of HIV-1 contributes to the pathogenesis of the virus
  • molecular mechanisms of through which the Vif protein of HIV-1 contributes to the pathogenesis of the virus
  • the use of macaque models to study lentivirus infection and persistence
