The colloquia of the Graduate School serve the continuous discussion of the ongoing doctoral and postdoctoral projects. In the colloquia, which regularly occur on a monthly basis at both locations, the doctoral candidates first present their project concept and ongoing work for discussion. Two doctoral candidates are always given the opportunity to present their work, so that at least twice a year they present the status of their work for discussion with the participation of both supervisors. If necessary, the two site colloquia are combined as a video conference. In addition to the joint work on the challenges of the project under discussion, the colloquia also serve to collectively discuss any problems that arise and to identify and discuss general issues.
