The MaRCN (Materials Research Coordination Network) is an NSF FAIR and Open Science Research Coordination Network to advance and coordinate FAIROS materials research nationally and internationally. MaRCN links the stakeholder of MaRDA to bridge fundamental gaps between materials data and data-intensive methods including artificialintelligence and machine learning. MaRCN also connects the US Materials Genome Initiative (MGI) to broader efforts to advance FAIR principles and Open Science ideas across the US science ecosystem. MaRCN  is a collaboration involving seven institutions: Johns Hopkins University (lead institution), SUNY at Buffalo, Duke University, Northwestern University, Purdue University, the University of Chicago, and the University of Texas, El Paso. MaRCN is supported by NSF award 2226414 from the Directorate for Mathematical and Physical Sciences and the Office of Advanced Cyberinfrastructure.
