The Convergence Accelerator, a program developed by the National Science Foundation (NSF) to invest in research towards developing high-impact solutions for societal issues, requests topic ideas for the 2023 cohort in a Dear Colleague Letter Request for Information (DCL/RFI). This program follows a three-tiered process, including topic ideation and convergence research phases one and two. This RFI seeks input from industry, institutions of higher education, non-profits, state and local governments, and other interested parties and represents the beginning stages of topic ideation and precedes community workshops to develop the final convergence research tracks, anticipated in FY 2023. Of particular interest to NSF are approaches to advance Critical and Emerging Technologies as described in the Multi-Agency Research and Development Priorities for FY 2023.
