Current research interests include the impact of HIV infection and antiretroviral therapy (ART) on T cell responses to co-pathogens (such as Mycobacterium tuberculosis) with a particular focus on the transcriptional regulation of immune responses.

KEY EXPERTISE:  T cell immunology, Infectious Diseases, HIV/TB co-infection.
