Description

The overall goal of the NIH fellowship, research training, and career development programs is to help ensure a highly trained, heterogeneous pool of scientists is available across appropriate scientific disciplines to address the Nation's biomedical, behavioral, and clinical research needs. NIH fellowships support the training of predoctoral and postdoctoral scientists, dual-degree investigators, and senior researchers.  More information about these fellowships is available on the NIH Research Training and Career Development website.

Note: This Notice of Funding Opportunity (NOFO) does not allow candidates to propose leading an independent clinical trial. However, candidates may propose research experience in a clinical trial led by a sponsor or co-sponsor.

Purpose 

The purpose of the Predoctoral to Postdoctoral Transition Award (Parent F99/K00) is to support promising graduate students as they complete their doctoral research training and transition to mentored postdoctoral career development opportunities in research areas relevant to the mission of participating NIH Institutes and Centers (ICs), preparing them to become productive, independent researchers.

Award Structure

The F99/K00 provides up to 5 years of support across two consecutive phases.

  • F99 Phase (Predoctoral): Provides 1 to 2 years of mentored research training to support completion of the research doctorate, including final experiments, dissertation preparation, and selection of a postdoctoral mentor. 
  • K00 Phase (Postdoctoral): Provides up to 3 years of mentored postdoctoral research and career development support, contingent upon successful completion of the doctoral degree requirements and securing a postdoctoral position in a research area relevant to the mission of the participating NIH ICs. The K00 research direction should be within the mission area of the NIH IC that awarded the F99 phase. 

A K00 award will be made only to support a PD/PI who has successfully completed F99-supported training, secured a postdoctoral appointment, and, in coordination with the applicant institution, submitted to NIH a strong research and career development plan to be carried out in a supportive and rigorous research environment. Candidates are expected to obtain a postdoctoral position at an institution other than the one where they conducted their doctoral research.
