To celebrate this landmark, we are designating this year's seminar series the CeDEx 25th Anniversary Series and it will include speakers with longstanding connections to the group. The programme can be found online and begins, with the first speaker Prof. Robert Sugden (UEA), on the 19th of February.

There will also be a dedicated one-day workshop to mark the anniversary at the University of Nottingham on 10th September 2025 (full details will be announced later).
