Principal Research Interests

  • Characterization of normative and altered mucosal immune responses of the gastrointestinal (GI)-associated lymphoid tissue (GALT) in the healthy and diseased human GI tract, e.g., in inflammatory bowel diseases (IBD), infectious diseases such as HIV infection
  • Facilitate translational testing in humans (observational studies, exploratory & Phase 1 trials)
  • Novel biomedical systems for preventing (topical/implant/vaccine) and treating/functional cure: HIV and other infectious diseases
