About Me


I’m a Postdoc at IST Austria, working in the group of Laszlo Erdös and Jan Maas. I’m mostly interested in probability theory, in particular the mathematical study of random growth models such as (totally) asymmetric exclusion processes or last passage percolation models, as well as related questions in e.g. combinatorics. I did my Phd in Bonn in Sep. 2015 with Patrik Ferrari on Shock Fluctuations in KPZ Growth models and spent a year as postdoc at ENS Paris, working with Jérémie Bouttier.

Here you can find my publications and preprints:
