About

I am the Co-Director of UNC Project-China and the Advisor of SESH Global. My background training is in the field of epidemiology, with an emphasis on HIV/STI epidemiology, study design, and data analysis. My research focuses on promoting HIV/STI testing and healthy behavior change among key populations. Specifically, I am interested in using crowdsourcing and other participatory methods to enhance health services. In addition, I am also interested in digital health/telemedicine, especially in the evaluation of digital health. I have co-authored more than 200 peer-reviewed publications.
