I have been at Stuttgart University since 2010 with a short break in spring 2013, in which I was at the LMU Munich for a substitute professorship in Applied Mathematics. In 2012 I habilitated at Stuttgart University. Before that I have worked as postdoc (Research Associate) for some time in London at Imperial College and at University Collge;  after studying and graduating from TU Bergakademie Freiberg.

Since 2015 I am a member of the International Board of Directors of ISAAC, the International Society for Analysis, its Applications and Computations.
