Dive into Research

Since 2023, I have been program lead for Dive into Research within Combinatorial Synergies. I am the contact for prospective organizers, support and propose events, and participate in funding decisions with the program committee.

With Michael Cuntz and Lukas Kühne, I co-organized Simplicial Arrangements and Matroids in Hannover in March 2025.

Dive into Research programmes

MATHS OPEN

Mathematics in public space: a mathematical public-art project that arose from my tilings proseminar, exhibited at ARTS OPEN in Frankfurt from July to September 2026. The installation was developed with the students.

Main Math Challenge

I initiated Main Math Challenge in 2022 and continue to organize it together with Noemi Kurt. The competition brings school students together to explore mathematics through several kinds of challenges, including the Creative Challenge.

Die Frankfurter Mathematik

I organized this public lecture series at Physikalischer Verein Frankfurt in 2025: five lectures by professors from our institute and one invited lecture, presenting current mathematical research to a wider audience.
