Brian Bot discusses the beginnings of an open ecosystem in mobile health (mHealth) research. Sage Bionetworks, a non-profit focused on open and collaborative biomedical research, aims to balance sharing data with participant privacy through participant-centered consent. Their mPower study had over 16,000 consented participants who opted to broadly share their data over 70% of the time. Some researchers worry this open approach could enable "research parasites" who use other researchers' data without contributing to the original study. Overall, the goal is to promote a research ecosystem where data can be openly shared and consumed by others.
