The Branco Weiss Fellowship, a fund administered by ETH Zurich
Branco Weiss Fellowship: Society in Science
The Branco Weiss Fellowship gives a small number of postdocs up to five years and up to 600,000 Swiss francs to do research that departs from the mainstream of their field, at an academic host anywhere in the world. It is open to every discipline and nationality, and it asks one more thing of its fellows than most schemes do: a real willingness to talk with society about the issues their work touches. ETH Zurich runs it and aims to name up to ten fellows a year.

How to apply
Apply online through ETH Zurich's eResearch system with a five-page research proposal, a one-page motivation letter explaining why the work departs from the mainstream, a CV, three publications, five reviewer suggestions and an invitation letter from the host mentor.
What it funds
A fellowship is a research grant of up to 600,000 Swiss francs for a project of up to five years. The money can cover any legitimate research cost: the fellow's own salary, in full or in part, at the host institution's normal rate, the salaries of doctoral students, equipment, consumables, travel and technical or secretarial help. It is paid to the host institution each year through ETH Zurich, under an agreement between the fellow, the host and ETH, and unspent funds must be returned at the end. Equipment costing more than 50,000 francs cannot be bought in the last two years, and no cost-free extensions are granted.
The fellow chooses the host. Any academic institution in the world qualifies if it is exceedingly well suited to the project, and a fellow may work at more than one. The mentor at the host must invite the fellow into the research group, provide a workplace and access to the infrastructure the project needs, and state how much independence the fellow will have.
Two phases
The five years are split in two. The first two and a half years are the pioneer phase. Before the end of the second year, the directorate reviews the project and visits the fellow, looking at whether the work is still original and whether the fellow is productive. If both are satisfactory, the fellow moves into the exploitation phase for the remaining two and a half years, and the grant agreement is extended.
Fellows are encouraged to look for faculty positions during the second phase and may take one up after the first year. Taking an academic post does not end the fellowship. Fellows start between 1 October and 1 January after they are selected, and they are expected to attend the fellowship's annual symposium in the Zurich area in person.
Who should apply
The fellowship is for postdocs with a record of outstanding achievement and a project that the directorate describes as departing from the mainstream of their discipline, often across disciplines. The programme says plainly that it does not usually fund mainstream research that other funders could support. Applicants must hold their PhD, or have passed the doctoral examination, by the 15 January deadline, and must have obtained it no more than five years earlier; only parental leave and illness or accident extend that window, by up to a year in total, and the leave must be documented to the office before applying.
Professors and lecturers, with or without tenure, cannot apply, and nor can scientists in permanent employment. There is no age limit and no restriction by nationality. Each mentor may support only one candidate per round, and applicants who were not selected before may apply again.
Science and society
What sets the fellowship apart is its second expectation. Fellows must show, in the proposal itself, that they are willing to engage in dialogue on social, cultural, political or economic questions beyond their own field. The directorate looks for rising researchers who want to reshape their fields and who will talk with the wider public about what that means.
How selection works
- Shortlist. The directorate, with experts from ETH Zurich and the University of Zurich, reduces the written applications to a shortlist. Applicants hear the result within about two months of the deadline.
- Peer review. Independent external experts review the shortlisted proposals, and reference letters are requested. The directorate then decides whom to invite to interview.
- Interview. Invited candidates give a presentation and answer questions about the project, the choice of lab and what they expect of and would bring to the fellowship. The July 2026 guidelines describe interviews of about 30 minutes held by video conference.
- Decision. The committee evaluates all the interviews and the directorate confirms the funding decisions; candidates hear by email within ten days.
Questions
Can I hold the fellowship at my current institution?
The fellowship does not bar it, but the host must be exceedingly well suited to the project, and the invitation letter must explain why it offers the best environment.
Do I need to submit a budget?
No. Budgets are not required at the application stage, and neither are reference letters.
Can I take a faculty job during the fellowship?
Yes. Fellows may start a faculty post after the first year, and doing so does not end the fellowship.
Are humanities and social science researchers eligible?
Yes. The fellowship is open to postdocs in all disciplines, including the natural sciences, engineering, social sciences and humanities.
How many fellowships are awarded?
Up to ten a year. The programme makes no effort to fill all ten; the number depends on how candidates perform at interview.
Can I reapply?
Yes. Applicants who were not selected before are welcome to apply again if they still meet the criteria.
