The GFaI Seminar is a series of events that has existed since the beginning of GFaI. It offers an excellent opportunity to get to know the main areas of work of the GFaI divisions and to participate in scientific discussions. The changing focus of the seminars in particular reflects what is happening in the GFaI well and helps to make results on current topics known. We place special emphasis on the fact that some of the lectures are given by students working for us. Here they learn how to present topics in a sound, understandable, interesting, and also entertaining way to a larger audience.
