Do you have a great idea on how to make scientific software BETTER and want to share it with the community?

The Better Scientific Software (BSSw) Fellowship program fosters and promotes practices, processes, and tools to improve developer productivity and software sustainability of scientific codes. Each 2027 BSSw Fellow will receive up to $25,000 for an activity that promotes better scientific software through a publicly available artifact. Activities can include organizing a workshop, preparing a tutorial, or creating content to engage the scientific software community.

We encourage applicants at all career stages, ranging from students through early-career, mid-career, and senior professionals.

Application Deadline

Applications for the 2027 Fellowships will be accepted through Friday, October 30, 2026. This is a firm deadline that will not be extended.
