I am a social demographer and behavioral scientist in the Department of Obstetrics, Gynecology & Reproductive Sciences, with a secondary appointment in the Department of Medicine, Center for AIDS Prevention Studies. My research crosses the disciplines of population studies, sociology and behavioral sciences, and has focused on examining the impacts of human mobility on HIV prevention and care outcomes, and particularly the contribution of women’s mobility to HIV epidemics in southern and eastern Africa. I develop interventions to address the unmet needs of mobile populations, including the study "Self-Test Strategies and Linkage Incentives to Improve ART and PrEP Uptake in Men", which tests a social network intervention to improve the HIV prevention and care outcomes in a population of highly mobile men in a high priority setting (fishermen in Kenya). I also lead qualitative and mixed methods studies within several clinical trials and implementation studies in health systems and communities in sub-Saharan Africa, applying behavioral and social theory to the analysis of empirical data to ascertain implementation pathways. I have used qualitative methods to design and adapt interventions, and to better understand structural and cultural aspects of health services utilization.
