NIH Small Research Grant Program
Supports short United States investigator projects through NIH small research pathways for focused feasibility work and clear pilot results.
The NIH Small Research Grant Program (R03) is the National Institutes of Health's small, investigator-initiated route for discrete research projects. Under parent announcement PA-25-302, it supports short, focused studies and excludes clinical trials.
The mechanism is designed for up to two years, with standard due dates in February, June, and October for new applications. It is active through Ja…
Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
Funds a small, self-contained clinical trial anywhere inside the institute's mission in child health and human development.
Funds a small project that can be finished quickly with limited resources — a pilot, a reanalysis, a method, or a piece of new research technology.
Funds one small self-contained project for a scientist holding a career development award from the diabetes, digestive and kidney institute.
Funds a pilot or feasibility study by a scientist early in an independent career in oral, dental or craniofacial research.
Funds basic biochemical or biological work on a protein from a published list — druggable, linked to a rare disease, and barely studied.
Funds a self-contained rehabilitation research project by a scientist establishing an independent career, including new technology development.
Funds one small self-contained project for a scholar already inside the Clinical and Translational Science Award network, on the way to a first full award.
Funds a small, self-contained study on adopting, spreading or dropping health practices, for work that needs less than a full project.
Funds a small, short-term grant for NIAMS K01, K08, K23 or K25 recipients moving toward a first independent R01.
Funds a short, non-renewable pilot project that gathers the preliminary data a new investigator needs for a full substance-use research grant.
Funds a small follow-on grant for NHLBI's own K01, K08, K23 or K25 awardees only, to extend or branch out from their K-award research.
Funds short pilot projects using samples and tools from NIH's Human Virome Program to study the body's viral ecosystem.
