European Committee for Future Accelerators (ECFA) is a body for long-range planning of European high-energy facilities. It has advisory status to CERN and to other organizations in ​the ECFA participating countries. In 2020, the ECFA Early-Career Researcher (ECR) Panel has been created to discuss all aspects that contribute in a broad sense to the future of the research field of particle physics. It has an advisory role to ECFA. This is a presentation of the Czech Republic representatives in ECFA ECR Panel and our activities.
