In this seminar, graduate students present each other their research or related issues. The intend is to give an insight in the current problems of the various research groups in our department. Therefore, the speakers are encouraged to adjust the level of details in their talk. Each talk should take 20 to 60 minutes.

Even though the seminar primarily addresses PhD students, we also welcome interested master students and postdocs.

For up-to-date information and announcements you may join the PhD seminar mailing list.
