Biography

My current research interests focus on the immunopathogenesis of Human Immunodeficiency Virus (HIV) /Acquired Immune Deficiency Syndrome (AIDS) and Hepatitis C Virus (HCV) and other virus infections including SARS-CoV-2. We are interested in understanding why chronic virus infections persist in the host. Current work is divided along the following lines:

  1. Examination of T cell immune response to HIV and HCV infection.
  2. Therapeutic and preventive vaccine strategies
  3. immunomodulation during virus infections
