Research software is critical to supporting science. This research software is essential to progress in almost all research fields, but it’s often not developed in an efficient or sustainable way, and knowledge is often locked away in individual laboratories or only shared via method papers that cannot directly be used by others. Researchers who develop software know their disciplines, but often don’t have training and understanding of best practices to ease development & maintainability and to encourage sustainability & reproducibility. And, developers don’t match the diversity of overall society or of user communities. As part of a recently funded NSF grant (https://www.nsf.gov/awardsearch/showAward?AWD_ID=1743188) we are trying to understand challenges to developing and maintaining sustainable software in science and also plan an institute that can address such concerns. This forum is meant to facilitate some of that discussion for the research software community.
