BayAK, which stands for Arbeitskreis Nachwuchsförderung an bayerischen Universitäten or the Working Committee for the Support of Young Researchers at Bavarian Universities, aims to improve conditions associated with doctoral and postdoctoral studies, including internationalization, establishing and maintaining central graduate centers, quality assurance, and more.

They are also a good source for information on conferences, workshops, and other events that deal with supporting young scientists, university research, and science management.

You can find more information (in German) on their website.
