Supervision & Procedure

The supervision of your thesis by a researcher of the department Trust in Digital Services (TDS) ensures that you can adequately address a relevant (theoretical or practical) problem with the help of a suitable scientific method (usually empirical) within the given processing time. Your supervisor is the number one contact person for all questions concerning the content and form of your thesis. Together you will create the table of contents, on which the famous "red thread" of your work depends. Typically, the contact time is most intensive in the initial phase of the thesis and decreases continuously until shortly before submission.


A characteristic of the department is the mandatory participation in the final colloquium. In the course of this event, you will present and "defend" your research results after submitting your thesis. Participation in the final colloquium is intended to give you the opportunity to become acquainted with relevant topics from our field of research and to help you reflect on your research results and learn to defend them in front of a professional audience.

The final colloquium is a compulsory event - both actively in the role as a speaker and passively in the role as a listener to the presentations of your fellow students. The final colloquium will count for 10% of the overall evaluation of your thesis.

Each speaker is allowed a maximum of 30 minutes. The presentation itself comprises a maximum of 15 minutes, followed by a discussion with fellow students and the departmental team of a maximum of 15 minutes.

The presentation can be given either in German or English. If the presentation is held in German, the presentation slides have to be prepared in English.

Either the TU Berlin's own template (see on the right) or your own presentation template can be used.
