Research & Clinical Interests
Research Interests: 

My primary research interest is improving TB screening and prevention in peripartum women and children in high HIV/TB burden settings. Recent work has focused on novel non-sputum based TB diagnostics and the effect of pregnancy on LTBI screening and prevention approaches, as well as collaborating with TB immunologist to better understand the unique feature of these populations and how they may effect TB pathogenesis.

Current projects:
