Are you planning on doing a PhD after finishing your degree? Have you already picked a topic and found a supervisor? Or have you secured a spot in a PhD program and found at least two persons agreeing to be part of the supervising committee?
Then it is time to apply for admission which you can also do in English. An important part of your application is a synopsis of your research project, including a timetable.
For questions, you are welcome to contact the head of the IDGS (Institute Chair)
