- Date: 6.10.25 - 8.10.25
- each talk will be based on one of the suggested publications below!
- at least one second paper fitting the talk topic will be identified and included into the presentation by the student
- 30 min presentation, 10-15 minutes discussion
- Language: English
- all participants attend all presentations
- all participants contribute to the discussions
Now:
- Look for a second paper connected to your selection
- use Web of Knowledge/ Web of Science or Google Scholar
- Discuss with your advisor (see below) the secondary literature you plan to use for your presentation soon, well in time before the final preparation of the slide material. Contact the advisor with suggestions.
- We suggest to talk to your advisor at least one more time before the seminar. You should go through preliminary presentation material in time for last changes.
