Research Interests

New approaches to the efficient implementation of Lattice Boltzmann Methods on heterogeneous High Performance Computers are explored.

My current main project is OpenLB – An Open Source High Performance Lattice Boltzmann Code for Heterogeneous CPU-GPU Clusters financed by NHR@KIT.

Theses (offered topics)

These topics are suggestions for an initial discussion. The actual topic can be adapted to fit the profile and interests of the student.
Also feel free to contact me with own thesis ideas at the intersection of LBM and HPC.
