Since January 2023, I am a Tenure-Track Juniorprofessor for probability theory at Potsdam University.
I'm interested in questions of universality in stochastics, for example why do the same distributions appear in very different contexts, such as random matrices and random growth models? These questions are related to combinatorics, mathematical physics, as well as numerics and algebra. I am equally interested in the mixing behavior of Markov chains, in particular the cutoff phenomenon.

I gave an online talk on the paper 12. The video is available on youtube: https://www.youtube.com/watch?v=9-lRu7J88ds&t=4s
I also gave a short (nine minutes) talk on the paper 13. The video is again available on youtube: https://www.youtube.com/watch?v=cfnaiM9s6gg
Here you can find some slides about shock fluctuations in TASEP, et voici une version courte en français.
In winter 24/25, I teach a seminar "Mathematics and Magic" for students getting a degree for future high school teachers. Further information are available on PULS.
