What this is
This NIH funding opportunity supports exploratory research (R21 mechanism) to advance fundamental understanding of genetic architecture in complex human traits—not clinical trials. Applicants must propose innovative theoretical frameworks and methodological approaches that integrate genetic, environmental, and social factors across biological scales. The research should leverage existing large-scale datasets, computational modeling, and cross-disciplinary collaboration. This is ideal for researchers developing new analytical tools, population genetics theory, or multi-omics integration approaches rather than traditional lab-based discovery.
Who can apply
Extremely broad eligibility: universities, nonprofits (501c3 and non-501c3), small businesses, for-profit companies, government agencies, tribal organizations, and school districts can apply. Solo researchers should apply through an eligible institution. No geographic restriction specified.
Eligible applicant types
- City or township governments
- County governments
- Nonprofits that do not have a 501(c)(3) status with the IRS, other than institutions of higher education
- Small businesses
- Private institutions of higher education
- State governments
- Others (see text field entitled "Additional Information on Eligibility" for clarification)
- Public housing authorities/Indian housing authorities
- Native American tribal organizations (other than Federally recognized tribal governments)
- Special district governments
- Independent school districts
- Nonprofits having a 501(c)(3) status with the IRS, other than institutions of higher education
- For profit organizations other than small businesses
- Native American tribal governments (Federally recognized)
- Public and State controlled institutions of higher education
Full description — from the agency
The goal of this NOFO is to support R21 applications for novel theory and methods development that better delineate how genetic and non-genetic factors contribute to complex trait variation across individuals, families, and populations. Approaches should be interdisciplinary across the natural and social sciences, account for interdependencies across scales of biological, social, and ecological organization, and make extensive use of theory, simulations, and validation using available large-scale datasets
