Research Interests

Welcome, fellow researchers! I'm a curious master student trying to navigate mathematics. I visit conferences out of my own pocket in order to listen to mathematicians and explore my favourite two subjects geometric topology and geometric group theory. You're probably on this page because you met me once!

Once, I went to Japan, visited some conferences, wrote my very first paper with professor Eiko Kin and developed a moderately known web-app, called Graphicayley. I finished my math/cs teaching degree in October 2025. Now I'm just a normal master student at HU Berlin. I do programming, teaching, paper reading and conferences. Please write me an E-mail if you're a busy professor and if you need someone to lessen your work load :)

Apart from maths? I like to sing in my university choir, I like to read books. I like to draw and I like computer games, especially strategic multiplayer games.
