She has also served as co-principal investigator on three other NIH grants for Rakai, and as principal investigator on Rakai grants from the WHO, World Bank, and numerous foundations. She is currently principal investigator on the NICHD-funded R01 “ARV effects on HIV epidemiology and behaviors, Rakai, Uganda” and on the Gates-funded “Trial of male circumcision: HIV, STD and behavioral effects in men, women and the community, Rakai Uganda” as well as co-principal investigator on the NIAID-funded "Randomized Trial of Male Circumcision". Within the Rakai Project, she has helped develop epidemiologic studies and large community-based HIV prevention trials, which incorporate intensive home-based sample and data collection procedures. She has served on multiple WHO, NIH, and other scientific advisory groups in the areas of HIV and STD prevention.

It is my fifth day here [in a mobile clinic set up in a private home]. Yesterday, I treated more than 70 people. I’m just alone here, listening, diagnosing and dispensing medications. You do the work of three people. We rent someone’s home on a daily basis and use as a clinic. The main cases we see are malaria, worms, arthritis, painful joints, respiratory tract infections, genital ulcers, even peptic ulcers and syphilis. The commonest [condition] is malaria. We treat with chloroquine and Panadol [acetaminophen]. We treat coughs, worms and anemia as well. I enjoy my work. I feel happy helping people.
