About me
In May 2010, after I received my Diploma degree in Informatics at the Technische Universität München (TUM), I started working as a PhD student of Univ.-Prof. Dr. Michael Bader, who had a position as a Junior Professor (JP) in the SGS group at the IPVS, Universität Stuttgart. The group was led by Prof. Dr. Marc-Alexander Schweitzer at the time. Shorty afterwards, Michael Bader accepted a position as Univ.-Prof. at TUM, so I moved back to Munich in November 2011 to continue my PhD studies as a member of the chair for Scientific Computing in Computer Science under Univ.-Prof. Dr. Hans-Joachim Bungartz, which has been my workplace since.
My topics of interest include High Performance Computing (HPC) for applications such as multi-phase flow in porous media and tsunami simulation, dynamically adaptive grids, parallelization of structured meshes and load balancing with space-filling curves.

Multimedia
This is a dynamically adaptive, parallel simulation of slice 0 in the SPE10 benchmark. The left video shows the log-scaled permeability (black to gray) and water saturation (blue = 0.2, pink = 1.0). The right video shows adaptive refinement and coarsening of the grid and the domain decomposition due to load balancing, marked by distinct colors.
Below is a simulation of the full 3D benchmark. Colors indicate the water saturation (blue = 0.2, pink = 1.0), the lower right corner has been clipped:
