معرفی
Gregor Gassner is a Professor at the University of Cologne's Mathematical Institute, specializing in numerical methods for fluid dynamics and high-performance computing. He leads research in entropy-stable discontinuous Galerkin (DG) methods, focusing on robust and efficient simulations of multi-scale problems governed by conservation laws. His work includes adaptive algorithms for compressible flows, magnetohydrodynamics (MHD), and oceanography, supported by an ERC Starting Grant targeting 'un-crashable' solvers.
Key research areas:
- Non-linear multi-scale simulations
- High-order DG methods
- Entropy stability and robustness
- Exascale computing (e.g., SCALEXA project)
- Adaptive mesh refinement
- Subcell limiting techniques
Publications emphasize advancements in DG schemes, split-form discretizations, and applications to aerodynamics, plasma physics, and geophysical flows. His ERC grant aims to unify efficacy and robustness in numerical methods.
Grants/Awards: ERC Starting Grant for developing robust numerical solvers.
Labs/Teams: Core scientist at the Center for Data and Simulation Science, leading the NumSim group.
