The U.S. National Science Foundation (NSF) is offering a grant opportunity titled "Civil Infrastructure Systems" aimed at supporting innovative research in the design, operation, and management of civil infrastructure. This program seeks to foster fundamental research that contributes to the development of smart, sustainable, and resilient communities, focusing on the interactions within civil infrastructure systems, including transportation, power, and water systems. The NSF encourages groundbreaking ideas that can transform research communities, particularly in areas such as system integration, big data analytics, and socio-technological connections, while explicitly excluding research focused solely on individual infrastructure components. Proposals are accepted at any time, and interested applicants can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance, with further details available at the NSF program description link.
