Dan Webster is the Principal Scientist of Digital Health for Sage Bionetworks, a non-profit research organization, where he conducts app-based remote research studies to detect and manage disease. Dan designed, implemented, and deployed the original iOS app-based Mole Mapper Melanoma Study, which uses the iPhone camera to quantitatively track potential pre-cancerous lesions over time. He was recognized with a 2017 STATNews Wunderkind Award for his work in digital health research. His scientific training spanned from the University of Wisconsin-Madison (Genetics) and Stanford (Cancer Biology), followed by training as a Damon Runyon Postdoctoral Research Fellow at the National Cancer Institute. His research combined genome engineering and bioinformatics to discover and functionally assess novel non-coding genes and regulatory elements in skin and hematologic cancers. Alongside his ongoing research, Dan currently serves as a scientific lead for the Digital Health Technology effort in the Precision Medicine Initiative's million-person, longitudinal 'All of Us' Research Program.
