PD Dr. rer. nat.
I currently hold a position as an interim professor within the numerical analysis group at Johannes Gutenberg University Mainz. Prior to joining JGU, I worked as a postdoctoral researcher at both the University of Zurich and the Technical University of Brunswick.
My research primarily revolves around the examination and advancement of numerical techniques applicable to ordinary and partial differential equations, with a specific focus on hyperbolic conservation/balance laws. I dedicate my efforts to exploring stability characteristics, the maintenance of physical constraints, and the approximation and convergence properties of these methods. To support my theoretical findings, I consistently complement them with numerical simulations.

On July 26, 2023, the DFG made the decision to approve funding for my project, which is titled "Dissipative Weak Solutions for Non-Viscous Single- and Multiphase Flows."
-
The DFG will award funding to my project on "Dissipative solutions for the Navier-Stokes-Korteweg system and their numerical treatment" over the next three years. The project is together with J. Giesselmann from the TU Darmstadt. It falls within the scope of the DFG's priority research program called "Complexity, Scales, Randomness" (CoScaRa).
