The GREEKC Action announces the possibility to apply for support for a Short-Term Scientific Missions (STSM) fellowship. This support comes in the form of a travel grant for an exchange visit between researchers involved in a COST Action. In particular young scientists from a COST country can visit an institution or laboratory in another COST country. These visits are aimed at fostering collaboration, sharing new techniques and infrastructure that may not be available in other participants’ institutions or laboratories. The STSMs in GREEKC are intended especially to foster collaboration in the area of biocuration, data standard and ontology development, and data sharing focusing on the topic of Gene Regulation.
