These include applications for Research Projects (R01, R21, RM1), Planning grants (R34), Program Projects and Research Centers (P30, P50), Cooperative Agreements (U01, UM1, U19), Research Career Development Awards (K99/R00, K12), Institutional Training Grants (T32), Research Education (R25), Research Resources (R24), Conference Awards (R13), Pioneer Awards (DP1, PD2), SBIR/STTR (R41,R42,R43, R44) applications and Contract proposals (N01).

Key Functions:

  • Convene Special Emphasis Panels (SEPs) or NIDA standing study sections for peer-review of applications and contract proposals
  • Implement NIH peer review policies
  • Participate in the development of Funding Opportunity Announcements
  • Conduct grantsmanship/outreach activities for the scientific community

Alert: For due dates on or after Jan 25, 2025 – changes coming to how most research grant applications will be reviewed. Learn about the new simplified review framework.
