The Research and Data Team

The Research and Data (RAD) team conducts research on digital solutions that are intended to improve the health and quality of life of individuals living in low-resource, underserved communities. We use a mixed-methods approach to build and evaluate digital tools and data analytics to inform our understanding of how digital tools are used and/or generate useful insights for improving healthcare programs.

Our research aims to advance the field of digital development through rigorous investigation of how current and emerging technologies are used and how they can be improved. Progress in digital development depends not only on validating digital technologies, but on the generation of programmatic insights that can go towards the improvement of digital solutions.
