At the Horizon Europe Cluster 4 Info Days, the European Commission presents the latest call topics from the Cluster 4 work programme. You have the chance to ask questions on these topics via slido during the event. A horizontal session on the afternoon of the second day includes valuable tips for newcomers as well as experienced proposers on how to use the various EC tools to their advantage, as well as presenting the services of the NCP system and the three NCP network projects Ideal-ist, NCP4Industry Plus and COSMOS4HE Plus. Recordings of the event can be found on YouTube afterwards.
