CRI Irvington Postdoctoral Fellowship 2026–2027: $228,000 in Stipend Over Three Years, a $5,000 Annual Institutional Allowance, and Bioinformatics Bootcamp Support for Immunologists Working on Cancer

CRI Irvington Postdoctoral Fellowship 2026–2027: $228,000 in Stipend Over Three Years, a $5,000 Annual Institutional Allowance, and Bioinformatics Bootcamp Support for Immunologists Working on Cancer

The Cancer Research Institute runs one of the longest-standing training awards in immunology, and its next deadline is close: September 1, 2026, with a second annual cycle following on March 1, 2027. The CRI Irvington Postdoctoral Fellowship gives a newly minted PhD or MD three years of protected salary support to work on the immune system’s role in cancer, in a lab of their choosing, at a non-profit institution anywhere in the world. There are no citizenship restrictions and no requirement to be based in the United States.

This is a training award before it is a research award. CRI states plainly that the program “emphasizes training through research,” and the application is built to test that: alongside the science, you must write about the specific gaps in your own skillset and how this particular lab and this particular project will close them. Applications that read as a strong project attached to an already-expert postdoc tend to miss the point of the mechanism.

Key Details

What the Fellowship Actually Pays

The financial package is straightforward and, unusually, fully protected. The stipend escalates across the three years: $74,000, then $76,000, then $78,000. On top of that, the host institution receives $5,000 annually, which the sponsor may spend on research supplies, conference travel, health insurance, or childcare. CRI names childcare explicitly, which matters for postdocs who are often at exactly the career stage where that cost lands.

The clause worth reading twice is this one: deductions for administrative overhead are not allowed from either the stipend or the institutional allowance. Some institutions habitually skim indirect costs off fellowship allowances; CRI forbids it. If your grants office pushes back, that sentence on the official page is your reference point, and it is worth resolving before you submit rather than after you win.

CRI also funds fellows to attend its Bioinformatics Bootcamp. Immunology has become a computational field — single-cell sequencing, spatial transcriptomics, repertoire analysis — and a wet-lab postdoc who cannot handle their own data is at a real disadvantage on the job market. Treat the bootcamp as part of the award’s value, and consider naming it in your training-goals section if computational skills are one of your genuine gaps.

The award does not include a separate research budget beyond the $5,000 allowance. This is a stipend-plus-allowance fellowship, not a project grant. Your sponsor’s existing funding is expected to cover the cost of the science, which is one reason the strength of the sponsor’s lab weighs so heavily in review.

Who Is Eligible

The eligibility rules are specific, and the most common disqualifier is timing.

Degree. You must hold a doctoral degree by the date the award activates — not by the application deadline. Senior PhD students can therefore apply before defending, provided the timeline works.

Experience ceiling. Applicants who will have five or more years of mentored research experience at the time of award activation are not eligible. Use your doctoral degree conferral date to calculate this. M.D. applicants do not count residency years toward the total. Because activation can be up to a year after the deadline, run the arithmetic against your intended start date, not against today.

Time already in the sponsor’s lab. Only in exceptional circumstances will CRI consider an applicant who will have spent three or more years in the sponsor’s lab by the fellowship start date. The award is meant to fund a training transition, not to backfill salary for someone already embedded.

Field. The work must be directly related to immunology or cancer immunology. CRI phrases the test as: the project “must fall into the broad field of immunology with relevance to solving the cancer problem.” Pure tumor biology with no immune axis does not qualify. Neither does immunology with no plausible line to cancer. Both halves need to be visible.

Host institution. Any non-profit institution, in the United States or abroad. Industry labs are out.

Sponsor. Your sponsor must hold a formal appointment at assistant professor rank or above. Only one fellow per sponsor may apply in a given round — so if a labmate is also applying on September 1, one of you needs to wait for March. A faculty sponsor may not hold more than three CRI-supported fellows at any one time. Ask your prospective sponsor both questions directly and early; discovering the cap in late August is a wasted cycle.

What Reviewers Are Judging

CRI names three review criteria on the program page, and they are worth quoting because they tell you how to allocate your effort:

1. The candidate’s qualifications, demonstrated track record, and potential for future impact.
2. The strength of the sponsor and the quality of the training environment.
3. The significance, innovation, and feasibility of the proposed research.

Two of the three are about people and setting rather than the experiments. That is a meaningful signal for a four-page proposal: a technically flawless aims page will not rescue a thin sponsor letter or an unclear account of why this lab, specifically.

CRI adds that the applicant and sponsor are together expected to show how the research advances understanding of the immune system’s role in cancer, how the fellowship supplies new skills and approaches, and — the one applicants most often neglect — “a clear trajectory toward independence.” That third point asks you to write about a career, not just a project. What will you know how to do in three years that you cannot do now, and what kind of independent program does that set up?

The program also emphasizes hypothesis-driven, mechanistic studies in both fundamental immunology and tumor immunology. Descriptive atlas-building or purely correlative profiling, without a mechanistic question underneath, sits awkwardly against that language.

Required Materials

Everything is submitted through CRI’s online application portal, which also routes institutional signatures through DocuSign. The full list:

• A description of your background and research accomplishments — maximum 500 words.
• A statement of the knowledge and skillsets you aim to gain, the gaps in your training to date, and how this opportunity specifically fills them (mentor and co-mentor lab opportunities, institutional resources, external training) — maximum 250 words.
• A list of other funding sources you have applied to or will apply to, with due dates.
• Your CV and bibliography. NIH biosketch format preferred. PDF.
• A project summary, including how the research is relevant to the immune system’s role in cancer or to treating cancer immunologically — maximum 500 words.
• A non-technical abstract explaining the importance and potential clinical relevance of the work, written for CRI’s lay Board of Trustees and used for fundraising — maximum 250 words.
• Specific aims — maximum 500 words.
• The research proposal (background, significance, materials and methods) — maximum 4 pages including tables and figures; references are excluded from the limit. PDF.
• A sponsor’s letter introducing you, describing the sponsor’s qualifications to direct the work, and containing an explicit assurance that the project will be conducted under the sponsor’s direct supervision. The sponsor must also state whether you wrote the application and whether any preliminary data was generated by you or by the lab before you arrived. PDF.
• The sponsor’s CV or biosketch plus a list of current research support. NIH biosketch preferred; if using a formal CV, limit the bibliography to the past five years. PDF.
• Two letters of recommendation. One must come from your thesis advisor (or, for M.D. applicants without one, another qualified individual). The second should come from someone well acquainted with your work. The sponsor may not write either letter. If your sponsor was also your thesis advisor, contact CRI for instructions.

Formatting rules are enforced: single-spaced, 12-point font or larger, PDF only, each file uploaded individually on the attachments page. Applications exceeding the stated page limits are disqualified. Incomplete applications are not considered.

The Timeline

Applications close at 11:59 p.m. Eastern Time on the deadline date. If a deadline falls on a weekend or holiday, submissions are accepted until 11:59 p.m. the following workday. September 1, 2026 falls on a Tuesday, so the deadline holds as stated.

Decisions arrive roughly 10 to 12 weeks after the deadline — for the September 2026 cycle, that points to mid-November through early December 2026. Fellowships may activate from four months after the deadline and no later than one year following it, always on the first of a month. A September 2026 applicant is therefore looking at a start date somewhere between January 2027 and September 2027, which gives real flexibility if you are still finishing a thesis or winding down a previous position.

Build backwards from that. Sponsor letters and recommendation letters are the items outside your control; ask for them in July, not the last week of August. The DocuSign signature chain is the other classic failure point — your application is not considered submitted until every signatory has signed. CRI’s own advice is to submit early precisely so there is time to fix an incomplete file.

Preparing a Competitive Application

Choose the sponsor deliberately, and write about the choice. Because the training environment is an explicit review criterion, the proposal should make clear what this lab offers that your PhD lab did not — a technique, a model system, a patient sample pipeline, a co-mentor with complementary expertise. Vague admiration for a famous PI is not an argument.

Use the 250-word training-gaps statement seriously. It is the shortest section and the one most likely to be written in a hurry. It is also the section that most directly answers the question CRI is asking. Name concrete gaps — computational analysis of single-cell data, in vivo modeling, human sample work, clinical correlate access — and name the concrete resources that close them.

Write the lay abstract for an actual lay reader. CRI says outright that this abstract goes to its Board of Trustees and is used for fundraising. Reviewers notice when a scientist can explain their work without jargon; trustees notice more. Read it aloud to someone outside your field before you submit.

Respect the four-page limit absolutely. Over-length proposals are disqualified — not marked down, disqualified. That includes tables and figures. Cut before the deadline, not at midnight.

Be honest about preliminary data provenance. The sponsor is asked to state whether the preliminary data was generated by you or existed in the lab before you arrived. An answer that contradicts the impression your proposal creates is worse than modest preliminary data honestly labeled.

Disclose other applications. The list of other funding sources is required. Applying to multiple fellowships is normal and expected; concealing it is the problem.

Common Mistakes

• Miscalculating the experience ceiling. The five-year limit is measured at award activation, which can be up to a year after the deadline. Applicants who calculate from the deadline sometimes discover too late that they age out.
• Two applicants from one lab in the same round. Only one fellow per sponsor may apply per round. Coordinate.
• A sponsor already at the three-fellow cap. Ask before you invest six weeks in the proposal.
• A project that is cancer biology, not cancer immunology. The immune axis has to be central, not decorative.
• Descriptive work with no hypothesis. The program language emphasizes hypothesis-driven, mechanistic studies.
• Assuming the sponsor can write a recommendation letter. They cannot. You need two other referees, one of them your thesis advisor.
• Letting the institutional signature lapse. Unsigned DocuSign steps mean an unsubmitted application, no matter how early you uploaded the PDFs.
• Letting your institution take overhead off the allowance. Not permitted. Flag it with your grants office up front.

Frequently Asked Questions

Do I need to be a U.S. citizen or work in the U.S.? No on both counts. There are no citizenship restrictions, and the fellowship may be held at a non-profit institution in the United States or abroad.

Can I apply before I have defended? Yes, provided you hold the doctoral degree by the date the award activates. Activation can be as late as one year after the deadline, which gives most late-stage students room.

Can M.D.s apply? Yes. M.D. applicants exclude residency years when calculating the five-year mentored-research ceiling.

Can I reapply if I am not funded? Yes. Resubmission at a subsequent deadline is permitted, provided the new application is improved to reflect progress, and the changes should be addressed within the resubmitted application.

Is there a project budget on top of the stipend? Only the $5,000 annual institutional allowance, spent at the sponsor’s discretion. Research costs are expected to be covered by the sponsor’s own funding.

What if my sponsor was also my thesis advisor? Contact CRI directly for instructions, since the sponsor cannot supply one of the two required recommendation letters.

How do I ask a question about the portal or send a recommendation letter separately? The official program page lists dedicated email addresses for technical application problems and for referees who need to email a scanned letter rather than upload it. Use the addresses shown on that page, and always include the applicant name and application ID in the subject line. The specific addresses are not reproduced here because the page serves them through an obfuscation layer.

Next Steps

1. Open the official program page and read the eligibility section against your own activation date.
2. Confirm with your prospective sponsor that no labmate is applying in the same round and that they are not already at three CRI fellows.
3. Ask your thesis advisor and second referee for letters now — six weeks before the deadline, not two.
4. Draft the 250-word training-gaps statement early. It is short, it is heavily weighted, and it usually needs several passes.
5. Start the institutional signature process well ahead of September 1, since an unsigned application is an unsubmitted one.
6. If the September 2026 cycle is too tight, aim at March 1, 2027 and use the extra six months to generate preliminary data.

The related CRI application resources — the program FAQ, the invention disclosure forms, and the standard revenue sharing agreement — are all linked from the same official page and are worth reviewing with your institution’s grants office before you sign anything.
