About

I am a mathematical physicist with a background in condensed matter theory focusing on quantum systems. One set of research topics broadly concerns the interplay of randomness and quantum effects as e.g. in quantum glasses and other disordered quantum systems. Another research topic are correlated many-body quantum systems and their emergent (topological) properties such as fractional quantum Hall or quantum spin systems. Mathematically speaking, this involves combining and uncovering techniques from analysis to probability such as random matrix or operator theory as well as spectral theory and methods from statistical mechanics.

I am currently the German representative and vice-chair in Commission 18: Mathematical Physics at IUPAP, and a member of the EC of Munich Center for Quantum Science and Technology. From 2015-2020 I served as the treasurer of the International Association of Mathematical Physics.
