I am a professor at the Physics Institute of the University of Zürich, where I lead the research group Theory of Topological Matter. We are consensed matter theorists, and the team investigates diverse aspects of topological phases of matter. Much of my recent work applies the ideas of homotopy theory to classify topology of single-particle Hamiltonians, with applications to topological insulators, semimetals and insulators, as well as to dissipative (non-Hermitian) and periodically driven (Floquet) systems. More lately, we have also ventured into the investigation of spectra and topological aspects of hyperbolic lattices.

I obtained my undegraduate degrees at Comenius University in Bratislava under the supervision of Richard Hlubina, and I did my doctoral studies at the Department of Physics of ETH Zürich in the group of Manfred Sigrist. Afterwards, I spend two years as the Gordon and Betty Moore Fellow at the Geballe Laboratory for Advanced Materials at Stanford University, and four years as an Ambizione Scientist in the CMT group at the Paul Scherrer Institute in Villigen, Switzerland. During the latter appointment, I have also been affiliated as an Associated Senior Scientist with the group of Prof. Titus Neupert at the University of Zürich.
