Matthias Ostermann

I am a PhD student of Prof. Roland Donninger at the Faculty of Mathematics of the University of Vienna. In my PhD project, I explore new techniques for the global stability analysis of blowup in nonlinear geometric wave equations.

Currently, I am holding a PraeDoc position which is supported by the Vienna School of Mathematics.
