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.
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
