Short Term Scientific Missions (STSM)


  • Call for applications for Short Term Scientific Missions (STMS) in the framework of the COST Action CA21146 (PURPLEGAIN).
  • Deadline for applications: 15th February 2023 (closed)
  • STSMs must be completed by 30th September 2023.

COST Action

COST Action CA21146

COST Action CA21146 is a four-year networking action that aims at creating a European network to share information, facilitating technology and knowledge transfer between the academic and industrial sectors, related to Purple Photosynthetic Bacteria (PPB) applications for resource recovery from organic waste sources. Resource recovery includes wastewater or organic waste, open or closed environments, in single or chain processes.

The network associates fundamental-focused and applied research groups, improving lab-scale technology optimization through mechanistic modeling. It benefits the technology transfer from applied-research groups to industry, considerably improving process design. PURPLEGAIN also aims to create a database for techno-economic, social and environmental impacts studies, which facilitates the marketability of both the PPB-based technologies and the products to extract. Some focused products are polyhydroxyalkanoates, single-cell proteins, biomass for energy, biomass as fertilizer, biohydrogen, carotenoids, terpenoids, organic acids, coenzyme Q10, and 5-aminolevulinic acid.


COST is an intergovernmental framework for European Cooperation in Science and Technology established to initiate networking and coordination of nationally funded research activities on a European level. It facilitates bringing good scientists together under light strategic guidance based on networks, called COST Actions, centred around research projects in fields that are of interest to COST countries and cooperating countries.



STSM applicants shall be engaged in an official research programme as a PhD Student or postdoctoral fellow or can be employed by, or affiliated to, an institution, organisation or legal entity which has within its remit a clear association with performing research.

The institutions/organisation or legal entities where applicants pursue their main strand of research are considered Home Institutions.

The Host Institution is the institution / organisation that will host the successful applicant.

More information

The following table shows the scenarios available to eligible STSM applicants:

The full list of Near Neighbour Countries (NNC) is as follows: Algeria, Armenia, Azerbaijan, Belarus, Egypt, Georgia, Jordan, Kosovo, Lebanon, Libya, Morocco, the Palestinian Authority, Russia, Syria, Tunisia, and Ukraine.

Note that both countries, home and host, must have joined the COST Action PURPLEGAIN.   

Participating COST country should have accepted the memorandum of understanding of this Action (see here) and that the home institution and the host institution must be located in two different countries. The nationality of the applicant is not a bar to eligibility.

Financial Support

Financial Support

An STSM Grant is a fixed financial contribution which takes into consideration the budget request of the applicant and the outcome of the evaluation of the STSM application. STSM Grants do not necessarily cover all expenses related to undertaking a given mission. A STSM Grant is a contribution to the overall travel, accommodation and meal expenses of the Grantee.

More information

The calculation of the financial contribution for each STSM shall respect the following criteria:

  • Up to a maximum of EUR 3 500 in total can be afforded to each successful applicant.
  • Up to a maximum of EUR 160 per day can be afforded for accommodation and meal expenses.

The Action Chair and the STSM Coordinator can approve differentiated country rates to cover accommodation and meal expenses based on the perceived cost of living in the host country.

Specific provisions have been introduced to enable researchers from ITC participating in the COST Action to request a pre-payment of 50% of their STSM Grant when they complete the first day of their STSM. In such case, the representative of the Host Institution shall confirm by e-mail to the Grant Holder that the STSM applicant has officially started the mission on day 1. Only then the Grant Holder can arrange the payment of 50% of the STSM grant. The remaining 50% of the Grant is payable once the administrative requirements have been satisfied after the STSM.

The COST Association and the Grant Holder of the Action cannot be considered as being an STSM grantee’s employer (unless it is in alignment with the Action deliverables in the latter case). STSM grantees shall make their own arrangements for all provisions related to personal security, health, taxation, social security and pension matters.

Evaluation process and result announcement

Evaluation process

When the Grant application is submitted, the Grant Awarding Coordinator is notified. The applicant, Action Chair and Vice Chair also receive a copy of the notification. The Grant Awarding Coordinator will be able to review and approve/reject the Grant application on behalf of the Management Committee (MC)

More information

The STSM coordinator will then propose a ranked list of applications to the management committee: chair and vice-chair, WG leaders, Grant Awarding coordinator, Science Communication Coordinator, Training Schools Coordinator, and Stakeholder Coordinator. In case of rejection, a justification needs to be encoded. The justification will be included in the e-notification to the applicant.

Evaluation will be based on the complementarity of the applicant and host group, the quality and scientific excellence of the research proposal, the relevance of the work plan for the achievement of PURPLEGAIN objectives, the impact on the career of the grantee, the potential to support new collaborations. There should be special considerations with respect to supporting COST policies on promoting gender balance, enabling Early Career Investigators (ECI) and applicants from ITC countries (Inclusiveness-Target-Countries), while broadening geographical inclusiveness.

The selection committee, composed of the Action Chair, the Grant Awarding coordinator and a representative of each WG, will evaluate the STSMs proposals within a month after the STSMs call deadline and will inform the grant holder of the successful evaluated proposals. The successful applicants will then receive an e-mail from the grant holder (Grant Letter Notification), stating the official approval of the STSM application, the granted budget and a payment request form which has to be completed after the completion of the STSM for the grant to be transferred. The Grant Letter outlines the rights and duties of the grantee and of the Grant Holder.

If the amount of funding by all applications within a call does not exceed the available budget, the applications are handled by the Grant Awarding coordinator only. The Grant Awarding coordinator then presents the list to the selection committee which must accept the funding of every application.

If there are more applications than funding is available, the following procedure takes place.

  1. A list of all applications (containing an informative summary as well as the names of the home and host institutions) is distributed to all members of the selection committee in form of a table in which every evaluator can mark which applications he or she can evaluate according to their field of expertise.
  2. To guarantee a fair and objective evaluation, an evaluator should have no affiliation with neither the home nor the host institution of the STSM proposal in question.
  3. All applications are evaluated by two members of the selection committee. The Grant Awarding coordinator distributes the proposals to the individual evaluators.
  4. The criteria given in the table below shall be applied for evaluation. The first criterion (a) is assessed by the Grant Awarding coordinator prior to the evaluation process.

  1. The evaluators report their evaluations to the Grant Awarding coordinator.
  2. The Grant Awarding coordinator ranks all evaluations and then reports the final result to the selection committee to be discussed and accepted. The STSM coordinator will approve the applications selected in the e-cost platform.

The applicants are informed about the decision reached.

After the STSM

1 day and 10 days after the end of the grant, the grantee receives a reminder to upload the report. The deadline to submit the report is 30 days from the end of the activity, within 15 days from the end date of the Grant Period or within a shorter timeframe as per Grant Holder/ Grant Awarding Coordinator’s request to meet reporting deadlines.

The grantee receives an e-notification to submit the report and other supporting documents on e-COST, the GH manager and the Grant Awarding Coordinator will be in copy of the notification. The grantee must complete the report template, upload, and submit it in e-COST along with a host approval letter of the report (free style). A scientific report template is available on-line here:

The Grant Awarding Coordinator is notified when the grantee submitted the report and must verify the validity and content of the report by clicking the link in the notification. After review of the report by the procedures agreed by the MC, the Grant Awarding Coordinator needs to encode its approval or rejection on behalf of the MC. Upon the recording of the payment, an e-notification is sent to the grantee, with a copy to the Grant Holder manager.
