The Global Research Network

The Our Voice Global Research Network was formed in 2016 with support from the Robert Wood Johnson Foundation. The goal of the Network, comprised of experts from every continent, is to build an agenda for robust research, implementation, and dissemination of Our Voice projects globally. In November 2016 and November 2017, Stanford hosted Network meetings aimed at building a research roadmap for the initiative and spurring application and evaluation of the model across a variety of cultures and settings. The lessons from these projects have expanded our understanding of the potential health equity impacts of citizen science, and have informed and enriched US-based Our Voice projects.
