Welcome to my web page at KIT .

Since January 2019 I have been working as a Postdoctoral Researcher at KIT within the Collaborative Research Center 1173 "Wave Phenomena: Analysis and Numerics".

My research is concerned both with the investigation of characterizing features connected with dispersive partial differential equations and the mathematical rigorous study of spectral properties of self-adjoint and non-self-adjoint Hamiltonians of quantum mechanics.

More information can be found on my personal web page.
