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 working as a member of the SCCS chair under Univ.-Prof. Dr. Hans-Joachim Bungartz, where I finished my PhD in 2016. Since August 2016 I have been employed in a private company.
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.
Research
During my PhD, I developed the software project sam(oa)², a framework for efficient, numerical solution of partial differential equations on HPC architectures based on space-filling curve traversal. Two applications were implemented: two-phase porous media flow and tsunami wave propagation.
Two-Phase Porous Media Flow
This is a dynamically adaptive, parallel simulation of the SPE10 benchmark, where the vertical axis has been scaled by a factor 5 for better visibility. Colors indicate the water saturation (blue = 0.2, pink = 1.0), the lower right corner has been clipped. A central well (I1) injects water into the domain and wells (P1, P2, P3, P4) at the four corners produce oil.
Below is a simulation of slice 0 of SPE10. 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.
Tsunami Wave Propagation
This is a dynamically adaptive, parallel simulation of the Tohoku tsunami 2011. The left video shows the Japanese coast line with exaggerated tsunami wave fronts (green: positive elevation, red: negative elevation). The right video shows a top view of the scenario, with focus on adaptive refinement and coarsening of the grid.
