I am a PhD student in mathematics at the Saarland university in Germany under the supervision of Laurent Bartholdi.

My research interests are group theory, both in geometric and algorithmic aspects, in particular concerning groups acting on rooted trees. I'm also interested in automata and formal language theory.
