On February 11–12, 2015, NIH hosted a workshop to discuss the opportunities and challenges around building a large research cohort focused on precision medicine and heard from several leading experts from many disciplines and sectors.  More than 2,000 people watched on videocast and more than 500 people engaged through WebEx, submitting comments and questions to the workshop panelists. The workshop panelists also took comments and questions from Twitter based on a lively discussion from the hashtag #PMINetwork.
