Management philosophy

The academic community determines the content and structure of the teaching and research. Decisions regarding these are made at the lowest possible level: by the departments, institutes and faculties whenever possible, and at University level if this is of demonstrable value or if circumstances so require. This philosophy, which has been so beneficial to our University, is ideally suited to a research university in which researchers are free to determine their own teaching and research agenda.
