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.
