My primary research interests lie in the areas of HIV transmission risk behavior determinants; sexually transmitted infections (STIs); hepatitis C; and depression in HIV-positive individuals, drug users, and other marginalized populations. I am also interested in designing and evaluating theory-grounded behavior change interventions, studying the role of micronutrients on various health outcomes, and advocating for translation of research findings into practice. My research to date has spanned the globe and involved diverse groups including international migrants, HIV-positive individuals, injecting drug users, men who have sex with men, female sex workers, traditional healers, policy makers, and school students. My present research projects include examinations of the determinants of STIs, hepatitis C, medication adherence, and depression; evaluation of a theory-based sexual risk reduction intervention; and a study of nutrient intake and its association with health outcomes among HIV-positive individuals.
