Research Summary

I am a physician researcher focused on open innovation and related crowdsourcing methods to spur creative new ideas. Crowdsourcing allows diverse groups of individuals to collectively solve a problem and then implement solutions. I have organized 62 crowdsourcing challenges to improve health, including 11 global challenge contests. Finalist ideas from these challenge contests have been included in World Health Organization guidelines, changed provincial and national health policies, and formed basis of new public health interventions. Data from six randomized controlled trials suggest that crowdsourcing challenges are effective. My team’s ongoing research uses crowdsourcing to enhance HIV service delivery among men who have sex with men in China (PI, NIAID 1R01AI114310), to use pay-it-forward to spur gonorrhea and chlamydia testing in China (PI, NIAID K24AI143471) and to create youth-friendly HIV self-testing services in Nigeria (Co-PI, NICHD UG3HD096929). My team works in partnership with the UNICEF/UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases (TDR) Social Innovation in Health Initiative as a China hub for social innovation.
