About me

I am an ETH Postdoctoral Fellow at the D-MATH at ETH Zürich. Before coming to Zürich, I did a one-year postdoc at Université de Neuchâtel. I finished my PhD at University of Vienna in 2015 under the supervision of Goulnara Arzhantseva.

Research interests

Geometric and analytic properties of groups
Gromov hyperbolic groups and generalizations
Small cancellation theory
Low-dimensional topology and CAT(0) geometry
Geometric and arithmetic constructions of expander graphs
