My research focuses on elucidating the drivers of the large latent TB reservoir in East Africa and developing interventions to prevent TB infection and to improve the TB care continuum for HIV-infected and uninfected children and adults living in sub-Saharan Africa. Clinically, I am the Assistant Director of the Infectious Diseases Clinic at ZSFG, and direct the SALUD clinic, a clinic within the Positive Health Practice "Ward 86" at ZSFG, that is dedicated to providing multidisciplinary care to monolingual Spanish-speaking HIV-infected patients.
