My research centers on development and application of novel analytical and study design methods to address problems in HIV prevention and care in resource-limited settings, with a focus on designing and evaluating individualized treatment strategies and population-level interventions. Currently, I am very interested in understanding how social networks communicate information, social support, as well as HIV-related outcomes, behaviors and beliefs, and how this knowledge can be used to create more effective prevention and care efforts and to identify high-risk individuals for targeted interventions.
