I am Associate Professor of Mathematics at Constructor University (formerly: Jacobs University). My main working area is mathematical physics, in particular many-body quantum mechanics.

I am part of the French-German DFG-ANR project "Effective Approximation and Dynamics of Many-Body Quantum Systems".

**We have one PhD position available: See here for details.**
