Research interests

With my PhD thesis I achieved my goal to contribute to the efficient simulation of unsteady, compressible flow. Herefore I developed efficient time integration methods in the context of space-discretized compressible Navier-Stokes equations and Euler equations. The efficiency and further important qualities of teh schemes such as stability and convergency were thoroughly analysed and visualized for the aim of better understanding. I thank the DFG for the funding of this project.

At the present my interests lie in the fields of Data Science and the IoT.
