Opportunity Information: Apply for PAR 23 071
The NIAID Physician-Scientist Pathway to Independence Award (K99/R00; PAR-23-071) is an NIH grant program meant to help clinically trained postdoctoral researchers move more quickly and successfully from a mentored postdoctoral role into an independent, tenure-track (or equivalent) faculty position. Its central goal is to grow and sustain the pipeline of physician-scientists by giving promising clinicians protected support during the vulnerable transition period when they are building an independent lab and competing for longer-term research funding. The program is positioned as part of NIAID's broader effort to strengthen the biomedical research workforce and directly addresses the widely recognized shortage of physician-scientists in the United States.
This is a two-phase "pathway to independence" award. The K99 phase supports a mentored postdoctoral period where the candidate continues research training and builds a strong record of productivity under supervision, while deliberately preparing for independence. The R00 phase provides independent research support after the awardee secures an independent faculty position, helping them launch their own research program with momentum. The overall structure is designed to reduce the gap between postdoctoral work and a stable independent appointment by offering continuity of funding as the investigator changes roles and, often, institutions.
A defining feature of this particular FOA is its clinical trial restriction. It is intended for applicants whose proposed research does not include serving as the lead investigator on an independent clinical trial, a clinical trial feasibility study, or an ancillary clinical trial. In other words, the candidate cannot propose to "run" their own clinical trial under this announcement. However, the FOA does allow the applicant to gain experience in a clinical trial setting if the trial is led by a mentor or co-mentor, which can be important for physician-scientists who need clinical research exposure but are not yet at the stage of directing a trial themselves. Applicants who do plan to lead a clinical trial (or an ancillary clinical trial) are directed to apply to a companion FOA that is specifically structured for that scenario.
The opportunity is offered by the National Institutes of Health (NIH), within NIAID, and is categorized as a discretionary grant in the health funding activity area (CFDA 93.855). The original closing date listed for this opportunity is January 7, 2026. The provided source information does not specify an award ceiling or the expected number of awards, which often means applicants need to consult the full FOA text and NIH policy documents for budgeting limits, allowable costs, and institute-specific guidance.
Eligibility to apply is broad on the organizational side, spanning many types of U.S.-based entities. Eligible applicants include public and private institutions of higher education, state and local governments (including counties, cities, townships, special districts, and independent school districts), federally recognized Native American tribal governments, certain tribal organizations that are not federally recognized, public housing/Indian housing authorities, nonprofits (with and without 501(c)(3) status), for-profit organizations (other than small businesses), and small businesses, as well as other categories NIH recognizes as eligible. The FOA also explicitly highlights additional eligible institution types such as Historically Black Colleges and Universities (HBCUs), Hispanic-serving Institutions, Tribally Controlled Colleges and Universities (TCCUs), Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISIs), faith-based or community-based organizations, regional organizations, and eligible federal agencies, along with U.S. territories or possessions.
At the same time, there are important restrictions related to foreign involvement. Non-domestic (non-U.S.) entities and non-domestic components of U.S. organizations are not eligible to apply as the applicant organization. Foreign components, as NIH defines them in the NIH Grants Policy Statement, are allowed, which generally means a U.S. applicant organization may include certain well-justified international elements in the research plan if they meet NIH requirements and are properly documented.
Taken together, this FOA is best understood as a targeted career development-to-independence bridge for physician-scientists: it funds the final stretch of mentored postdoctoral development and then provides early independent support once a faculty role is secured, while specifically excluding projects where the candidate would be the lead for an independent clinical trial.Apply for PAR 23 071

FAQs: NIAID Physician-Scientist Pathway to Independence Award (K99/R00; PAR-23-071)
What is the NIAID Physician-Scientist Pathway to Independence Award (K99/R00; PAR-23-071)?
It is an NIH/NIAID grant program designed to help clinically trained postdoctoral researchers transition from a mentored postdoctoral position into an independent, tenure-track (or equivalent) faculty role. The award is structured to provide continuity of support across that transition so candidates can build independence and compete for longer-term research funding.
What is the main purpose of this program?
The central goal is to grow and sustain the physician-scientist pipeline by providing protected support during the high-risk transition period between postdoctoral training and independent faculty appointment. It is positioned as part of NIAID's broader effort to strengthen the biomedical research workforce and address the recognized shortage of physician-scientists in the United States.
Who is this award intended to support?
The program is meant for clinically trained postdoctoral researchers (physician-scientists in training) who are preparing to move into an independent faculty position and start an independent research program.
How is the award structured?
This is a two-phase "pathway to independence" award:
- K99 phase: A mentored postdoctoral period supporting continued research training, strong supervised productivity, and deliberate preparation for independence.
- R00 phase: Independent research support that begins after the awardee secures an independent faculty position, helping launch a new research program with momentum.
What happens during the K99 (mentored) phase?
During the K99 phase, the candidate remains in a mentored postdoctoral setting, continues research training, and builds a strong record of productivity while actively preparing to become independent.
What triggers the R00 (independent) phase?
The R00 phase is intended to start after the awardee obtains an independent, tenure-track (or equivalent) faculty position. It is designed to support the early stage of running an independent research program.
Why does this award emphasize continuity of funding?
The structure is designed to reduce the gap between postdoctoral work and a stable independent appointment by providing a bridge of support as the investigator changes roles and often changes institutions.
Can the proposed research include a clinical trial led by the candidate?
No. A defining feature of this FOA is its clinical trial restriction. The proposed research is intended to exclude situations where the candidate would serve as the lead investigator on an independent clinical trial, a clinical trial feasibility study, or an ancillary clinical trial.
Is any clinical trial experience allowed under this FOA?
Yes. The FOA allows the applicant to gain experience in a clinical trial setting as long as the clinical trial is led by a mentor or co-mentor. This can provide clinical research exposure without the candidate directing the trial.
What if an applicant plans to lead a clinical trial?
Applicants who plan to lead a clinical trial (including an ancillary clinical trial) are directed to apply to a companion FOA that is specifically structured for candidates who will lead a trial.
Which agency and institute offer this opportunity?
The opportunity is offered by the National Institutes of Health (NIH), within the National Institute of Allergy and Infectious Diseases (NIAID).
What type of funding mechanism is this categorized as?
It is categorized as a discretionary grant in the health funding activity area and is listed under CFDA 93.855.
What is the closing date for this opportunity?
The original closing date listed for this opportunity is January 7, 2026.
Is there an award ceiling or a stated number of awards?
The provided information does not specify an award ceiling or the expected number of awards. In practice, that typically means applicants need to consult the full FOA text and relevant NIH policy documents for budgeting limits, allowable costs, and any institute-specific guidance.
What kinds of organizations are eligible to apply?
Eligibility on the organizational side is broad and spans many types of U.S.-based entities, including:
- Public and private institutions of higher education
- State and local governments (including counties, cities, townships, special districts, and independent school districts)
- Federally recognized Native American tribal governments
- Tribal organizations that are not federally recognized (certain categories)
- Public housing/Indian housing authorities
- Nonprofits (with or without 501(c)(3) status)
- For-profit organizations (other than small businesses)
- Small businesses
- Other categories NIH recognizes as eligible
Are specific institution types explicitly highlighted as eligible?
Yes. The FOA explicitly highlights a range of additional eligible institution types such as HBCUs, Hispanic-serving Institutions, Tribally Controlled Colleges and Universities (TCCUs), Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISIs), faith-based or community-based organizations, regional organizations, eligible federal agencies, and U.S. territories or possessions.
Are non-U.S. (foreign) organizations eligible to apply as the applicant?
No. Non-domestic (non-U.S.) entities are not eligible to apply as the applicant organization under this FOA, based on the information provided.
Can a U.S. organization apply if it has a non-domestic (foreign) component?
Non-domestic components of U.S. organizations are not eligible to apply as the applicant organization. However, foreign components (as defined by NIH in the NIH Grants Policy Statement) are allowed, meaning a U.S. applicant may include certain well-justified international elements in the research plan if they meet NIH requirements and are properly documented.
What is meant by a "foreign component" in this context?
The FOA references the NIH definition of "foreign components" as described in the NIH Grants Policy Statement. The key point from the provided information is that foreign components are allowed, while non-U.S. entities and non-domestic applicant components are not eligible to apply as the applicant organization.
What is the overall takeaway for applicants deciding if this FOA fits?
This FOA is best understood as a targeted bridge from mentored postdoctoral development to early independence for physician-scientists. It supports a mentored training period followed by independent support after a faculty position is secured, and it specifically excludes applications where the candidate would lead an independent clinical trial (including feasibility or ancillary clinical trials).
