Our team had a strong participation at the 1st Osiris Users and Developers Workshop organized at UCLA from Sep 18 and Sep 20 (a joint organisation between UCLA and IST). With over 50 participants it also an excellent opportunity to learn about all the exciting developments in Osiris, also some of the cool physics being explored, and, of course, meet again our alumni and friends (in the photo, from left to right, Fabrizio DG, Anton H, Kevin S, Fabio C, Diana A, Ricardo F, Paulo A, Thomas G, Giannandrea I). The website of the workshop, including presentations, is here. The next workshop will be held at IST in 2018.
