NSF’s Harnessing the Data Revolution (HDR) Big Idea is a national-scale activity to enable new modes of data-driven discovery that will address fundamental questions at the frontiers of science and engineering. HDR, a NSF-wide activity, is generating new knowledge and understanding, and accelerating discovery and innovation. The HDR vision is realized through an interrelated set of efforts in foundations of data science; data-intensive research in science and engineering; and education and workforce development. In 2019, the HDR Big Idea launched three parallel efforts (tracks) in pursuit of these aims. Click here to learn more.
