What is a STSM

Short-term scientific missions (STSMs)


Short-term scientific missions (STSM) are exchange visits between researchers involved in a COST Action, allowing scientists to visit an institution or laboratory in another COST country. They are aimed at fostering collaboration, sharing new techniques and infrastructure that may not be available in other participants’ institutions or laboratories. STSM are intended especially for (but not restricted to) young researchers.

STSM applicants must be engaged in a research programme as a postgraduate student or postdoctoral fellow, or be employed by or officially affiliated to an institution or legal entity. This institution is considered as the “home institution”. Institutions may be public or private entities. STSMs are aimed at supporting individual mobility and at strengthening the existing networks and fostering collaborations by allowing scientists to visit an institution or laboratory (“host institution”) in another Participating COST Country, or in approved COST Near Neighbor Countries (NNC) institutions or in approved International Partners Countries (IPC) institutions.

A STSM should specifically contribute to the scientific objectives of the COST Action, while at the same time allowing applicants to learn new techniques or gain access to specific instruments and/or methods not available in their own institutions.

COST rules on STSMs in general:
– duration: 5 – 90 days;
– max. grant of 2500 Euro (up to 160 Euro per day; up to 500 Euro for travel expenses).

Specifically, Early-Stage Researchers (ESRs) may extend the STSM beyond 90 days. For such STSMs, following rules apply:
– duration: 91 – 180 days;
– max. grant of 3500 Euro (again: up to 160 Euro per day; up to 500 Euro for travel expenses).

Calls and collection dates for STSM applications are periodically announced by ESTC, Prof Stavros Koulouridis. STSM applications are subject to approval procedure.
