Best-practice example. Each doctoral student in our programme has a supervisor and a co-supervisor. The co-supervisor is a DKCC faculty member from a different discipline. S/he supports the students with interdisciplinary issues and co-guides the research project. The thesis supervisor remains the primary person responsible for scientific questions and for supporting and monitoring the successful completion of the PhD project (e.g. contents, timing, and publications). The students and their supervisors meet regularly to discuss the student’s progress and observe project development. Meetings with the co-supervisors generally take place less frequently, depending on the research progress and questions of the students.
