I am a mathematician based in Bonn, Germany. Previously I have done research at the Department of Mathematics, ETH
Zürich and the Mathematical Institute of the University of Bonn. My PhD supervisor, at the latter institution, was
Ursula Hamenstädt.

Arithmetic geometry, more specifically arithmetic groups, Fuchsian groups, models of curves over number fields, connection with low-dimensional topology and geometry, dessins d'enfants, anabelian
geometry, fundamental groups and Galois groups
