The Steering Committee, headed by the MAINZ Director, consists of elected PIs and the two PhD Student Representatives. The Steering Committee is the main decision-making body of the school and sets annual objectives and policy aims for MAINZ in accordance with the school’s program. It oversees training and dissemination actions as well as the administrative, legal and financial status of the school. Furthermore, it decides on the readjustment of the research and training program of MAINZ and implements changes of the faculty if necessary. Therefore, the Steering Committee regularly evaluates the performance of participating PIs, ensures the quality of selection processes for PhD students by appointing a Selection Committee, and monitors the progress of the school as a whole.
