## Informal PhD Seminar

The Informal PhD Seminar is a running seminar organized by PhD students at the MMGS. Its main aim is fighting off the slumber of the term break, and getting to know what is happening in other areas of the department. It happens every Wednesday at 16:00, hybrid on Zoom and in-person, starting from the 9th of February. Talks are roughly 45 minutes long, one or two per session. Here are some possible prompts:
1. One Open Problem in Your Research Area
2. A Fun Puzzle (explain the puzzle, then give time to the audience to solve it!)
5. Why Should We Care About...

### Contacts

For information, or for signing up for a talk, contact azul.fatal [at] uni-muenster.de, mamelio [at] uni-muenster.de or sramello [at] uni-muenster.de.
The seminar is currently on hiatus during the Summer semester 2022.
