Enrollment for doctoral studies
According to the Doctoral Degree Regulations, you must be enrolled for the entire duration of your doctoral studies. In the Dr. rer. nat. program, this only begins after approval of the dissertation announcement, which must be submitted at the beginning of the work in accordance with § 4 of the Doctoral Degree Regulations. Enrollment for Dr. rer. nat. is therefore only possible after approval of the dissertation announcement.
The key qualifications and seminar hours in accordance with Annex 6 of the Doctoral Degree Regulations can generally only be acquired after approval of the dissertation announcement.
Further information on enrollment (and re-registration) can be found here.
Information on submitting the dissertation announcement
Dissertation announcements can be submitted throughout the year. However, these are collected and reviewed once per semester.
The latest dates for submission to the Promotionsbüro (Doctoral office) are January 15 and June 15 of each year.
In your own interest, you should submit your dissertation announcement in good time.
Please submit the documents to the Doctoral office by post or in person, not by e-mail.
