Miscellaneous/Outreach
- I have contributed to Mathenacht 2024 with a workshop for high school students. You can find the exercise catalogues here (in German).
- I have co-organized FRICO 2024, a workshop organized for and by PhD students in combinatorial optimization.
- I like to be involved in Tag der Mathematik, an event with a mathematics competition for high school students in Berlin. In 2023, I gave a talk, in 2024, I graded problems.
- I am currently the team leader for a math competitions team at TU Berlin. We are an informal but highly motivated team that meets regularly to solve problems and study various topics in mathematics. If you would like to join us in meetings or future competitions, or engage with our team in any other way, please do not hesitate to contact me.
