The first annual workshop for Pure and Data-driven Quantum Chemistry (PDQC) took place from 28.07.2022 to 30.07.2022 in Braunschweig. The group of Vera Krewald from TU Darmstadt as well as the group of Christopher Stein from TU Munich (2022 still University of Duisburg-Essen) visited us in Braunschweig. An exciting scientific program with a lecture, talks and posters as well as a trip on the river Oker ensured a successful retreat.
