COST (European Cooperation in Science and Technology) is a funding organisation for research and innovation networks. COST Actions help connect research initiatives across Europe and beyond and enable researchers and innovators to grow their ideas in any science and technology field by sharing them with their peers. A COST Action is an interdisciplinary research network that brings researchers and innovators together to investigate a topic of their choice for 4 years. COST Actions are typically made up of researchers from academia, SMEs, public institutions and other relevant organisations or interested parties. Open to all science and technology fields, including new and emerging fields, COST Actions offer an inclusive, pan-European environment for individuals of all levels of seniority to grow their professional research networks and boost their careers. About 60 new COST Actions have been approved last May and will start in October 2024. To participate, search for Actions and research areas that you are interested in via the  Browse Actions page and either contact the Action representatives, or go directly to their website to find what opportunities they have on offer.
