NIBIB Small Grant Program
Funds short-duration interdisciplinary pilots at the interface of biomedical and physical science.
The NIBIB Small Grant Program uses the R03 mechanism to support investigator-initiated work at the interface of biomedical science and the mathematical, physical, or engineering sciences. It is aimed at new technologies with clinical translation potential, especially projects that require real technical development rather than a light feasibility study. Awards provide up to $50,000 in direct costs per year for up to two years, with standard NIH R03 deadlines on February 16, June 16, and October 16. The current parent announcement is PA-20-200, although NIBIB notes that NIH may have reissued the parent R03 notice and applicants should confirm the active version before applying. This is a good match for US university-led teams that can define a focused technical problem, show why the biomedical use case matters, and keep the scope tight enough for a two-year award. NIBIB also encourages applicants to contact program staff before submission, which makes relevance a practical part of the application strategy rather than an afterthought.
Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
