Other Activities

Physics Olympiad

I was part of the Academic Committee at the European Physics Olympiad (2021, 2022). I have been co-organizing the Swiss Physics Olympiad since 2015. This mainly involves creating and marking problems, teaching, maintaining the website, and accompanying students to international competitions.
