Biography

Dr. John-Stewart's major research interest is in studies of HIV-1 infection in Africa. She directs several large cohort studies aimed at defining mechanisms of HIV-1 transmission between sexual partners and from mothers to infants in Kenya. Particular research interests include prevention of mother-to-child HIV-1 transmission (PMTCT) clinical trials, implementation science and evaluation studies, pediatric HIV-1 studies, HIV-1 treatment programs and evaluation. Her group also focuses on maternal-child epidemiologic studies in the context of infectious diseases including studies of the mechanism of breastfeeding protective effects, child growth and neurocognitive outcomes, preterm birth, viral infections with EBV, CMV, and TB.  She collaborates with Drs. Carey Farquhar, Barbra Richardson, Julie Overbaugh, Michael Chung, R. Scott McClelland, Jennifer Slyker, Sarah Benki-Nugent, and Judd Walson.
