The programme will include 30 min (20+10) talks as well as longer tutorials and discussion sessions.
The recorded talks, discussion and tutorials will be uploaded to our YouTube channel, where you can already find talks from the first GRPV workshop in 2022.
All sessions will take place in the Old Library, unless otherwise stated.
* Please note that the tutorial sessions on Day 2 and Day 3 will take place in parallel. For each parallel session, one will be held in the Old Library and the other in the Hovenden Room.
