Huntington's Disease Foundation Postdoctoral Fellowship 2027: Up to $100,000 a Year for Two Years of Huntington's Disease Research

Huntington’s Disease Foundation Postdoctoral Fellowship 2027: Up to $100,000 a Year for Two Years of Huntington’s Disease Research

The Huntington’s Disease Foundation (HDF) 2027 Postdoctoral Fellowship is a focused research award for early-career scientists whose work has a direct connection to Huntington’s disease (HD). The Foundation accepts a short Letter of Intent (LOI) before inviting selected applicants to submit a full application. The 2027 LOI window runs from August 17 through October 1, 2026, with submissions due by 11:59 p.m. Eastern Time on October 1. A full application, if requested, will be due on January 6, 2027.

The fellowship can provide up to $100,000 per year for two years. HDF says this total may cover salary, supplies, equipment, and benefits, with salary support taking priority. It does not pay indirect costs. The award can begin in March or April 2027, after the Foundation’s review and funding decision process. Because HDF reviews the scientific relevance, novelty, significance, premise, approach, applicant, environment, and budget, a strong submission needs more than an interesting disease connection. It should show a credible question, a feasible plan, and a clear reason the work could advance understanding of HD or disease-modifying treatments.

This guide focuses on the postdoctoral fellowship. HDF uses the same annual LOI process for one-year research grants aimed at more experienced investigators, but the eligibility, career stage, and mentoring expectations differ. Applicants should choose the program that matches their role and track record rather than treating the two awards as interchangeable.

Key details at a glance

The initial deadline in the table is the date most applicants need to act on now. An LOI is not the full scientific application, but it is a competitive gate: HDF invites only the most impactful LOIs to continue. The later January deadline matters only after the Foundation requests a full application.

What the fellowship supports

HDF describes its postdoctoral fellowships as a way to cultivate interest in Huntington’s disease research by supporting promising early-career scientists. The research should have a direct application to HD. The Foundation’s stated priorities include work that advances understanding of fundamental disease mechanisms or contributes to disease-modifying therapeutics. That scope leaves room for different methods, but it does not make HD a secondary example in an otherwise unrelated project.

The maximum award is $100,000 per year for two years. HDF explains that the amount includes salary support, supplies, equipment, and benefits. Salary should be budgeted first, followed by eligible direct research costs. An applicant should therefore prepare a realistic budget that connects each requested cost to the proposed work. The award is not an unrestricted personal stipend, and the Foundation does not pay institutional overhead or indirect costs.

The two-year structure is useful for a defined postdoctoral project with milestones that can be reached within the award period. It is not a promise to fund every part of a long research program. The proposal should identify the central question, the experiments or analyses that address it, the evidence that would support or challenge the hypothesis, and the point at which the project will produce a meaningful result. HDF also expects the recipient to commit full-time professional effort to the funded project.

The Foundation funds researchers in laboratories around the world, and both U.S. and non-U.S. citizens can be eligible. The precise rules for the laboratory location and any work authorization should be checked against the current instructions. Funding is tied to the approved research project, and awardees have ongoing reporting obligations, including six-month progress reports and a final report.

Who is a good fit

The fellowship is designed for researchers at the early-career stage, including postdoctoral fellows and scientists up to seven years after completing a PhD. HDF gives priority to investigators who are committed to a career in HD research, so the application should make that commitment visible through the question, training environment, past work, and next steps.

A good fit may be working on molecular mechanisms, neuronal biology, genetics, animal or cellular models, therapeutic discovery, biomarkers, clinical questions, computational analysis, or another area that can be tied directly to HD. The method matters less than the disease relevance and the quality of the proposed advance. A technically sophisticated project can still be a poor match if the connection to HD is only stated in the final paragraph.

The fellowship also fits applicants who need a new research environment to develop independence. HDF requires postdoctoral training in a laboratory different from the graduate thesis laboratory. A move between labs should be more than a change of address: explain what new expertise, model system, technology, mentorship, or intellectual perspective the proposed environment contributes.

Applicants who are already established investigators may be better served by HDF’s one-year Research Grant. That program can provide up to $100,000 for a year and is intended as seed funding for experienced researchers who need preliminary data for larger awards. The postdoctoral fellowship is the more suitable route when the application is centered on early-career training, a mentor, and the applicant’s development as an independent HD researcher.

Eligibility requirements to verify

HDF’s current 2027 instructions state that applicants must meet all listed requirements. The most important conditions are date-sensitive, so applicants should calculate them against the official cycle rather than rely on a general description of “early career.”

First, the applicant must be within five years of receiving a PhD, or an MD or DVM when that degree was awarded later, as of October 1, 2026. The current instructions say that someone who received the relevant degree before October 1, 2021 is not eligible for this cycle. HDF allows an applicant to apply before defending the thesis, but the degree must be awarded by the planned award activation date of August 1, 2027.

Second, the applicant must have begun, or be scheduled to begin, work in the proposed postdoctoral laboratory between August 1, 2025 and July 31, 2027. The proposed supervisor must provide a letter confirming acceptance of the applicant to the laboratory. The supervisor letter must also address the institution’s willingness to administer the award, the applicant’s expected role, the size of the research group, and the level of independence the applicant will have.

Third, the postdoctoral training must take place in a laboratory different from the graduate thesis laboratory. Remaining in the thesis lab for a short transition period after receiving the degree can be acceptable, but planning to remain there for the postdoctoral period is not. Applicants should discuss edge cases with HDF before submitting an LOI if their move, co-mentoring arrangement, or degree timing is unusual.

Finally, applicants conducting postdoctoral research in a Howard Hughes Medical Institute laboratory are excluded from the 2027 competition. The Foundation also says that U.S. and non-U.S. citizens may apply, and it supports international researchers. Non-U.S. applicants should read the current instructions carefully to confirm that their proposed laboratory and work arrangement meet the location rules.

How to apply through ProposalCentral

The first stage is an LOI submitted through ProposalCentral. HDF limits the LOI to 500 words or 3,500 characters, in text-only format without special characters or formatting. The short document must establish direct relevance to Huntington’s disease. It should identify the problem, the proposed insight or intervention, and why the work could be impactful. Since the Foundation’s scientific advisory reviewers use the LOI to decide who proceeds, it should be written as a genuine research case, not as a compressed biography.

HDF’s committee reviews HD-related LOIs independently and invites only the most impactful submissions to full application. The Foundation does not provide feedback on LOIs. That makes the first stage a one-shot test of clarity and fit: an applicant should not assume there will be an opportunity to repair an ambiguous disease connection later.

Applicants invited forward complete the full application in ProposalCentral. The application includes applicant information, a research proposal, reference letters and a supervisor letter, and demographic information. The applicant information includes education, peer-reviewed publications, honors and awards, a 300-word thesis summary, and contact information for the institution’s grants or sponsored-programs official.

The research proposal has a 250-word abstract field and a research-proposal upload. HDF limits the proposal to seven total pages: five single-spaced pages for the research plan, including figures and tables, and two pages for the literature cited. The Foundation specifies margin and font rules, including one-half-inch margins and minimum text sizes. It asks applicants to be concise because expert reviewers do not need an extended textbook introduction.

The application must include four letters: three reference letters and one proposed-supervisor letter. One reference should normally come from the thesis advisor, although HDF allows an alternate faculty member most familiar with the thesis work when the advisor cannot provide a letter. The proposed supervisor cannot be one of the three referees. Letters are entered by the writers through the online system rather than uploaded as PDF files.

2027 timeline and planning dates

The LOI portal opens August 17, 2026. The LOI must be submitted by October 1 at 11:59 p.m. ET. HDF will notify invited full-application candidates on November 19. The full application deadline is January 6, 2027 at 11:59 p.m. ET. The Foundation expects funding decisions in late February 2027, with awards beginning in March or April.

The letters have their own deadline. All three references and the supervisor letter must be received by November 1, 2026 at 11:59 p.m. ET for a complete LOI-to-full application process. HDF says incomplete applications are reviewed as submitted and that it will not extend the application deadline or accept submissions after the deadline. Once October 1 passes, applicants cannot edit the full application or add or change a reference.

An applicant should treat August 17 as the portal date, not the start of preparation. Before the window opens, confirm the degree date, proposed lab dates, supervisor acceptance, lab-change requirement, and HD relevance. Draft the LOI early enough to ask a mentor or colleague whether a reader outside the exact subfield can understand the disease problem and the proposed advance.

Materials and evidence to prepare

Begin with a concise project map. Write down the central hypothesis, the most important experiment or analysis, the expected result, the alternative interpretation, and the next decision that follows. This map can guide both the 500-word LOI and the later seven-page proposal. It also exposes projects that are too broad for two years or that depend on untested methods without a fallback.

Gather evidence for the premise. HDF explicitly evaluates scientific premise, including strong evidence from the literature or preliminary data. Preliminary data need not prove the hypothesis, but they should show why the proposed approach is plausible and what observation motivates the next step. Cite the relevant work precisely and distinguish your own results from published findings or pilot observations.

Prepare a CV or résumé with publications, preprints where appropriate, honors, methods, and evidence of research responsibility. The application asks for a publication list and a thesis summary, so make those materials readable to reviewers who may know the disease field but not every technique. The thesis summary should help the panel see how the proposed postdoctoral project extends or changes your prior work.

The supervisor letter is not a routine admission confirmation. HDF asks it to describe the applicant’s role, the research group’s size, the expected independence, and the institution’s willingness to administer the award. Discuss these points with the proposed supervisor in advance. Make sure the project is genuinely the applicant’s work within the lab’s broader program, and identify what mentoring and infrastructure will be available.

The budget should connect requested costs to milestones. Include salary first, then eligible benefits, supplies, equipment, or publication costs as appropriate. Do not include indirect costs, and do not request a large equipment line merely because the laboratory has a general wish list. If a facility, core, collaborator, or co-mentor is essential, explain the contribution and how the environment makes the project feasible.

How HDF reviews proposals

The Foundation lists nine review areas: relevance, novelty, significance, scientific premise, approach, applicant, environment, budget, and compliance with NIH guidelines. These categories describe a connected argument. Relevance asks whether the project advances HD understanding or therapeutics. Novelty and significance ask whether the work could produce a meaningful conceptual advance, useful tool, dataset, or therapeutic strategy. Approach asks whether the plan is technically and statistically sound.

Feasibility is especially important for an award limited to two years. State the milestones that should be reached in year one and year two. Explain how the experiments are prioritized if a result is negative or a method fails. If animal or human-subject work is involved, show that the proposed numbers and design can support the conclusion, while staying within the page limit.

The applicant and environment sections should reinforce each other. Your record should show that you can carry out the work, while the proposed lab should provide what you do not yet have. A famous host laboratory is not enough if the supervisor letter does not explain your independence or the practical access to facilities, samples, models, and expertise.

HDF’s Scientific Advisory Board and wider scientific reviewers assess applications, and at least three reviewers conduct primary review of full applications. A substantial portion is reviewed by the full advisory panel. Write for both the specialist who knows your method and the broader reviewer who needs a clear explanation of why the result matters to HD research.

Preparation strategy and common mistakes

The most common strategic error is treating HD relevance as a label. If the project would be unchanged if the disease name were replaced with another condition, it is probably not sufficiently specific. Identify the HD mechanism, patient need, therapeutic barrier, or disease-modifying question that makes the study belong in this competition.

Another error is using all seven proposal pages for background. HDF says extensive background is unnecessary for expert reviewers. Use the space for a precise rationale, rigorous design, controls, milestones, interpretation, and contingency plans. Keep figures readable and make captions carry useful information.

Do not wait until the full-application invitation to contact letter writers. The October 1 LOI deadline and November 1 letter deadline are different. Supervisors and referees receive online submission requests, and letters are typed or pasted into the portal rather than uploaded as PDFs. Confirm that each writer knows the format, the exact deadline, and the email address from which HDF will send the request.

Avoid budget overlap. HDF asks reviewers to consider overlap with other ongoing grants. Explain what this award pays for, what another award pays for, and why the HDF project remains distinct. Also check for the one-award-per-laboratory constraint: HDF says a laboratory may have only one HDF awardee at a time, and if several applicants from one lab become finalists, only one can be awarded.

Finally, read the current instructions immediately before submitting. Dates and eligibility rules are updated by cycle, and HDF says that all dates are subject to change. The Foundation’s page is the authority for the 2027 competition.

Frequently asked questions

Is the 2027 fellowship open now?

The LOI portal opens August 17, 2026. It remains open through October 1, 2026 at 11:59 p.m. ET.

How much can a postdoctoral fellow receive?

HDF offers up to $100,000 per year for two years. The total can cover salary, supplies, equipment, and benefits. The Foundation does not pay indirect costs, and salary should take priority in the budget.

Do I submit a full proposal immediately?

No. You first submit a 500-word or 3,500-character LOI. HDF invites selected LOI applicants to submit a full application. Invited applications are due January 6, 2027.

Can researchers outside the United States apply?

Yes. HDF says U.S. and non-U.S. citizens can apply and that it funds international researchers. Non-U.S. applicants must verify that their proposed laboratory and work arrangement satisfy the current location rules.

Can I remain in my PhD laboratory?

No, not for the postdoctoral training period. HDF requires a different laboratory from the graduate thesis lab, although a short transition after the degree may be acceptable.

What letters are required?

The full application requires three reference letters and one proposed-supervisor letter. The supervisor cannot also serve as one of the three referees. The letters must arrive by November 1, 2026.

When would funding start?

HDF expects awards to begin in March or April 2027. The Foundation’s instructions also identify August 1, 2027 as the award activation date for the degree-timing eligibility rule, so applicants should follow the date that applies to their award paperwork.

Official application and next steps

Read the Huntington’s Disease Foundation grant and postdoctoral fellowship application page before preparing the LOI. Use its ProposalCentral application link to create or access the submission. The official page also includes HDF’s FAQs on eligibility, review criteria, funding limits, reporting, and post-award administration.

Before August 17, confirm that your degree date fits the October 1, 2026 rule, your postdoctoral lab is eligible and different from your thesis lab, and your proposed supervisor is willing to provide the required support letter. Then write an HD-specific LOI that states the scientific problem and the expected advance in plain, testable terms. If invited, expand that argument into a seven-page proposal with rigorous design, a defensible budget, and milestones that fit two years. Keep the October 1 LOI deadline, November 1 letter deadline, and January 6 full-application deadline on separate calendar reminders.
