Since May 2019 I am affiliated with the Department of Applied Mathematics. Before I was a post-doc at the University of Hamburg and the University of Wuppertal, where I also held a temporary professor position (`Vertretungsprofessor') in Fall 2018/19. My mathematical origins (undergraduate studies) are at the TU Wien.

My research interests broadly center around (functional) analysis and particularly operator theory with applications in the analysis and control of pde's.

In more detail, some research foci have been semigroup theory, functional calculus, input-to-state stability of infinite-dimensional systems and funnel control.

Besides, I like optimising constants and Crouzeix's conjecture.
