Head of the Research Group
Numerical Methods in Geosciences
KlimaCampus, University of Hamburg

Welcome

Gaining insight in geo and climate sciences is closely related to demanding computer simulation, since we cannot use the world in which we live as a laboratory. It is my goal as an applied mathematician to contribute basic methods for supporting such simulations.

Research focus

Together with my group we develop numerical methods, which can represent multi-scale geophysical processes. These are for example:

• adaptive three-dimensional fluid flow simulation of cloud formation processes
• adaptive mesh generation for tsunami simulation
