Branco Weiss Fellowship 2027: Up to CHF 600,000 Over Five Years for Postdoctoral Researchers Pursuing Unconventional Science Beyond the Mainstream
The Branco Weiss Fellowship – Society in Science awards early-career postdoctoral researchers up to CHF 600,000 over five years to pursue independent, unconventional research in any discipline at a host institution of their choice, with a January 15, 2027 deadline.
Branco Weiss Fellowship 2027: Up to CHF 600,000 Over Five Years for Postdoctoral Researchers Pursuing Unconventional Science Beyond the Mainstream
Most postdoctoral funding rewards researchers for fitting neatly into an established field: a well-defined problem, a predictable method, a lab that already works on the topic. The Branco Weiss Fellowship does the opposite. It is built to back people whose research does not fit — scientists and scholars with an idea that sits between disciplines, challenges accepted wisdom, or is simply too risky for a conventional grant panel to fund. In exchange for that ambition, it offers something almost no other postdoctoral award can match: up to CHF 600,000 over five years, spendable however the project genuinely needs, at any host institution in the world the fellow chooses.
For the 2027 cycle, applications open in October 2026 and close on January 15, 2027. If you have recently finished a PhD, have a bold and unconventional research plan, and have not yet taken a faculty position, this is one of the most flexible and generous early-career fellowships available anywhere. This guide explains what the fellowship provides, who it fits, how the money can be used, what reviewers look for, and how to prepare an application that stands out.

What the Fellowship Offers
A Branco Weiss Fellowship amounts to a maximum of CHF 600,000 across up to five years — approximately CHF 120,000 per year. What makes the money unusual is not only the size but the freedom. The funding can be used to cover all legitimate costs of the research: the fellow’s own salary, equipment, consumables, travel, and even personnel to build a small team around the project. There is no requirement to spend it in a fixed way, which means a fellow can shape the budget around what the science actually demands rather than what a rigid grant category permits.
The fellowship is structured in two phases. The first roughly two and a half years form a “pioneer phase,” during which the fellow establishes the project and builds momentum; this period includes a site visit and review before the second year ends. The remaining two and a half years form an “exploitation phase,” where the fellow develops and delivers on the promise of the early work. This design gives long-horizon projects the time they need — five years is far longer than the one- or two-year windows typical of postdoctoral funding, and it is long enough to pursue an idea that might not pay off quickly.
Equally important is portability. Branco Weiss fellows are not tied to a single sponsoring university or country. A fellow can carry out the funded research at a host institution of their choice, which in practice means almost any strong research environment worldwide. That flexibility lets applicants seek out the specific lab, collaborators, equipment, or intellectual community that best suits an unconventional project, rather than being limited to wherever they happened to complete their PhD.
Beyond the money, fellows join a community. The program brings its fellows together at an annual symposium in the Greater Zurich Area, which fellows are expected to attend in person. That gathering is part of the fellowship’s founding idea — that science should stay in dialogue with society — and it connects fellows across fields who would otherwise never meet.
Who Should Apply
The fellowship is aimed at outstanding early-career researchers at a specific stage: after the PhD, but before a first faculty appointment. Concretely, for the 2027 cycle you must officially hold a PhD by January 15, 2027, meaning you have at least successfully passed your defense by that date, and you must have obtained that PhD no more than five years before the deadline. You must also not hold, and not have held, a faculty-equivalent position such as an assistant professor or lecturer role.
There is a sensible allowance for career interruptions. Time away for parental leave or for illness or accident can extend the five-year eligibility window, generally by up to one year, so applicants who have taken legitimate breaks are not penalized for them.
Crucially, the fellowship is open across the full breadth of academic inquiry. Applicants may come from the natural sciences, engineering, the social sciences, or the humanities. What unites successful candidates is not a field but a disposition: a project that departs from the mainstream of research in its discipline, a record of outstanding scientific achievement, and a genuine willingness to engage in dialogue on the social, cultural, political, or economic dimensions of their work. If your research plan would make a conventional funder nervous precisely because it is original, this fellowship may be the right home for it.
The Unconventional-Research Test
More than most awards, the Branco Weiss Fellowship is explicit that ordinary excellence is not enough. Reviewers are looking for research that “departs from the mainstream” — work that crosses disciplinary boundaries, questions established assumptions, or opens a genuinely new line of inquiry. The application even asks, in a dedicated one-page letter of motivation, for you to explain why your research differs from the mainstream.
This is where many strong scientists misjudge the fellowship. A technically superb but incremental proposal — a logical next step in a well-populated field — is unlikely to succeed, no matter how solid. Conversely, a bold idea with clear scientific grounding and a credible path forward is exactly the profile the fellowship exists to support. As you prepare, be honest with yourself: could a dozen other labs write more or less the same proposal? If so, sharpen the angle that only you would take. Articulate the assumption you are challenging, the boundary you are crossing, or the risk you are willing to run — and then show that you have the skill and plan to make it work.
Application Materials
Applications are submitted online, with each document uploaded as a PDF (maximum 5 MB per file and 15 MB in total). For the 2027 round you should prepare:
- Letter of motivation (maximum 1 page): explaining why your research differs from the mainstream. This is your chance to frame the whole application around originality.
- Research proposal (maximum 5 pages): including timelines, tentative milestones, and references. This is the intellectual core — it must be ambitious but also concrete about how you will proceed.
- Curriculum vitae (maximum 4 pages): a focused account of your training, achievements, and trajectory.
- Host institution letter: stating why you are invited to the host group and why your research project is supported there. This confirms that a strong research environment is ready to host you.
- Three best publications: your strongest peer-reviewed journal articles or book chapters. Dissertations and full books are not accepted here.
- Five reviewer suggestions: entered directly in the online application system.
- PhD documentation: a scan of your PhD certificate or confirmation of successful examination.
Notably, the fellowship does not require reference letters or a detailed budget at the application stage, which keeps the initial submission lean and focused on ideas. If you are selected, official PhD certificates may be requested later (around April), so make sure your documentation is in order.
One procedural point worth flagging early: a mentor or host can only support one candidate per application round. If you are hoping a particular researcher will write your host letter, confirm early that they are not already committed to another applicant for the same cycle.
Timeline and Deadline
The rhythm of the 2027 cycle is straightforward but tight. Applications open in October 2026, and the deadline is January 15, 2027. Because eligibility is measured against that January 15 date — both your PhD status and the five-year window — it is worth confirming your own dates carefully well before you submit.
That autumn-to-winter window is short, and much of the hardest work happens before it even opens. Identifying and securing a host group, refining a genuinely unconventional proposal, and choosing the right five reviewers all take time. Treat the October opening as the moment you submit polished materials, not the moment you start writing. If selected candidates are asked for official PhD certificates around April, expect the overall selection process to run through the first part of 2027.
Preparation Strategy
The strongest applications tend to share a few habits. Start by nailing the central claim: in one or two sentences, what is the unconventional idea, and why does it matter? If you cannot state it crisply, reviewers will not be able to either. Build the five-page proposal outward from that claim, using the required timelines and milestones to prove that the ambition is matched by a workable plan. Ambition without a credible path reads as wishful; a plan without ambition reads as ordinary. You need both.
Choose your host institution deliberately. Because the fellowship is portable, the host is a signal of judgment: it should be the place that genuinely strengthens the project, whether for its equipment, its collaborators, or its intellectual culture. Ask your prospective host early, and give them time to write a letter that speaks specifically to why your project belongs in their group.
Select the three publications and five reviewers with care. Your best three papers should demonstrate both quality and the kind of independent thinking the fellowship prizes; if some of your strongest work is interdisciplinary, use it. Reviewer suggestions should be experts who can genuinely assess a boundary-crossing project — not only people within your immediate subfield.
Finally, remember the dialogue-with-society expectation. The fellowship values researchers who can situate their work in a broader social, cultural, political, or economic context and who will show up to the annual symposium ready to engage. Weaving that awareness into your motivation letter, without forcing it, reinforces that you understand what this particular fellowship is about.
Common Mistakes to Avoid
The most frequent misstep is submitting a proposal that is excellent but conventional. This fellowship is not a general prize for the best postdoc; it specifically rewards departure from the mainstream, and a safe proposal undercuts your case. A second mistake is treating the host institution letter as a formality — a generic, unenthusiastic letter suggests you do not have a real home for the work. Third, applicants sometimes ignore the format limits: the one-page motivation letter, five-page proposal, four-page CV, and file-size caps are firm, and overshooting signals carelessness. Fourth, leaving the host arrangement and reviewer choices to the last minute can leave you scrambling in December. And finally, some candidates misjudge eligibility, forgetting that both the PhD-by-January-15 requirement and the five-year cap are measured against the deadline date, with only illness or parental leave as recognized extensions.
Frequently Asked Questions
How many fellowships are awarded each year? The program aims to award up to about ten fellowships annually, making it highly competitive.
Can I use the money for my own salary? Yes. The funding can cover salary, equipment, travel, consumables, and personnel — the full range of legitimate research costs.
Do I have to move to Switzerland? No. You conduct your research at a host institution of your choice, which can be almost anywhere in the world. You are, however, expected to attend the annual symposium in the Greater Zurich Area in person.
What fields are eligible? The natural sciences, engineering, the social sciences, and the humanities are all eligible. The key requirement is that the project departs from the mainstream of its discipline.
Do I need reference letters to apply? Not at the application stage. Instead of reference letters, you submit five reviewer suggestions and a host institution letter. Official PhD certificates may be requested in April if you are selected.
Can I still apply if I recently took a faculty job? No. You must not currently hold, or have previously held, a faculty-equivalent position such as an assistant professor or lecturer. You may, however, take up a faculty position after the first fellowship year without losing the fellowship.
