During the week from the 5-9 of November, the workshop "Physics and Psychology of Human Crowd Dynamics" took place at the prestigious Lorentz Center in Leiden (The Netherlands). The workshop was co-chaired by Dr Enrico Ronchi (Lund University), Dr Alessandro Corbetta and Prof Federico Toschi (Technical University of Eindhoven), Prof John Drury (University of Sussex), and Prof Armin Seyfried (Jülich Supercomputing Centre). The workshop included a multi-disciplinary mix of researchers and practitioners working in the field of crowd dynamics. The workshop was a great success and it paved the way for the future research agenda in the field of crowd dynamics.
