As scheduled we had a 4 year kick off today. In the presence of essentially all participants, plus two new prospective PhD students, Arianna and Magdy, who will be joining the APC group in the fall, we have had exciting talks by Thibault, Hamza, and Gabriel, summarizing the status of the project implementation and followed by a discussion of the last year goals and plans. This fully zoom meeting will be followed by a series of more targeted lectures and hands-on tutorials. Stay tune then !
