I'm a mathematics graduate student at the University of Bonn, where I'm specialising in number theory. Since 2019 I've been co-building BMUCO alongside other like-minded university students — we've run programs including in research, outreach and education reaching 20k people worldwide, co-hosted the Abel Symposium 2025, and interviewed Fields Medalists and Nobel Laureates. Right now I'm focused on the formalisation of graduate mathematics in Lean 4 and its implications for AI. Outside mathematics I work on climate policy and quantitative finance.
