While the full-time lecturers are part of the directorate ad personam, the private lecturers, associate lecturers, doctoral students, assistants, postdocs and research assistants elect their own representation. They are thus cordially invited to participate in the Mittelbau meetings that take place twice a semester. These meetings serve as a forum and the Mittelbau representatives safeguard the interests of its members in the Directors Meetings. The concerns of the Mittelbau include ensuring excellent research and teaching conditions, fair employment conditions and the targeted promotion of young academics. In addition, the Mittelbau facilitates interdepartmental exchange and networking at the Institute.
