Program
Our workshop in Heidelberg will be from Monday morning the 7-th of October 2019 to Friday the 11-th 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.
