As an epidemiologist and a medical doctor, I study sexual and reproductive health with a goal of preventing sexually transmitted infections (STIs) and improving reproductive outcomes for women and men. I have a particular interest understanding how context (e.g., endemic disease, social norms, demographic factors, and cultural and institutional structures) influences health and disease. Methodologically, I focus on using innovative methods to obtain high quality data about sensitive and stigmatized topics. Much of my research has been conducted in eastern and southern Africa, and I have had the opportunity to work with fantastic research collaborators.
