Program
Our workshop in Heidelberg will be from Monday morning the 10th of October 2022 to Friday the 14th 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.
