About

I am an infectious diseases physician and social scientist with a special interest in crowdsourcing and related participatory methods. Crowdsourcing has a diverse group of individuals attempt to solve a problem and then share selected solutions with the public. I have used crowdsourcing to develop HIV interventions and enhance community engagement. I organized 100 crowdsourcing open calls to improve health, including 13 global challenge contests. Finalist ideas from these open calls have informed regional, national, and global guidelines. In partnership with WHO/TDR, I led the development of a practical guide on crowdsourcing for health and health research.
