In 2014 I was still very much lurking on the fringes. I was never officially part of it but I ended up holding a lecture there in 2019. I became good friends with Michael Lackner the director and am now good friends with his successor Andrea Bréard. I still work with/for Petra Schmidl who was also a fellow there
