## Eligibility & scope

Allows Swiss applicants to include co-applicants in Denmark, Norway, Sweden or the Netherlands (up to 50% of SNSF budget) or in the UK for humanities/social sciences projects (up to 30%, co-funded by ESRC/AHRC); no separate application to the foreign agency required but country-specific employment regulations apply.

## Summary

The SNSF International Co-Investigator Scheme lets Swiss-based researchers add co-applicants in Denmark, Norway, Sweden, the Netherlands or the UK to a regular SNSF project funding application, without filing a separate application to the foreign agency. It targets researchers already applying for SNSF project funding who want to build a cross-border team, with UK co-applicants limited to humanities and social sciences projects co-funded by ESRC/AHRC. Applications are assessed together with the regular project funding round, and the call runs twice a year.

## Who should apply

- Researchers based in Switzerland eligible for SNSF project funding
- Teams building a consortium with a co-applicant in Denmark, Norway, Sweden or the Netherlands
- Humanities and social sciences teams partnering with a UK co-applicant funded via ESRC/AHRC
- Applicants submitting a regular project funding proposal in the same round

## Key dates

- Deadlines twice yearly: 1 April and 1 October
- Single-stage application, evaluated together with regular SNSF project funding applications
- Call runs biannually

## Tips for applicants

- Budget the foreign co-applicant's share within the stated caps, up to 50% of the SNSF budget for Nordic/Dutch partners, up to 30% for UK humanities/social sciences partners co-funded by ESRC/AHRC.
- No separate application to the partner country's funding agency is needed, but check country-specific employment regulations for the co-applicant's post before submitting.
- Align the international co-investigator component tightly with the main project funding proposal, since both are evaluated together in the same submission.
