For everyone who is not a mathematician, the papers and talks linked elsewhere on this site are most likely gibberish. Explaining the details of my research to a general audience is not something I know how to do.

What I can do, is tell you something about some basic topics in my area of research. Because research is so highly specialized, there is a lot of maths between the boring stuff you might have learned in school and the study-5-years-to-understand-anything topics that research is typically about. In fact, these intermediate levels contain some exciting insights that aren’t too difficult to explain.

Or at least I think so… You’re probably in a better position to judge it:

Inspired by the contest by 3blue1brown over the summer of 2021, I made an educational video on the mathematics behind rainbows. It communicates visually (without formulas) how the true story is more complicated but also more beautiful than “different wavelengths reflect at different angles”:

In print

Chalkdust is a “magazine for the mathematically curious”.

I wrote an article on Hamiltonian mechanics and Noether’s theorem for issue 15.

In the classroom

From 2016 until 2019 I led a math circle in Berlin. Math circles are extracurricular activities for secondary school students with an interest in mathematics. In Berlin they are coordinated by the MSG Leonhard Euler. The circles meet once a week during the school year to solve puzzles, tackle olympiad-style maths problems and learn about mathematical topics that aren’t usually discussed in school.
