(Work in progress, please come back later for an updated program)
Our workshop in Heidelberg will be from Monday morning the 23rd of September 2024 to Friday the 27th at lunch time. The program includes alternating theory sessions with lectures and hands-on tutorials. We expect participants to arrive on Sunday evening (or Monday morning early) and leave on Friday.
We will add links to tutorials and powerpoint presentations in the week before the workshop.
