As a biostatistician I have primarily worked in the area of HIV and sexually transmitted disease control in Africa and in the area of public health ophthalmology. Inspired by scientific investigations in these arears, my methodological research focuses on analysis of longitudinal and survival data with complicated correlation structures. A particular area of my current research is to develop an analytical framework to evaluate the population impact of the scale-up of HIV prevention programs. In addition to my biostatistical expertise, I received training in social and behavioral sciences in the context of HIV prevention, to learn theories and methods about behavioral approaches to promote health seeking behaviors, and have intense interests to apply and develop statistical methods for better understanding of social norms and social support in HIV high risk populations.
