We study flow and deformation ("geodynamics") of the solid Earth and other planetary bodies using computational modeling. Research covers a wide range of scales, from features that can be observed by a geologist in the field, to global, 3D spherical models, and a correspondingly wide range of topics, from crustal and lithospheric deformation, to the geochemical evolution of entire planets over billions of years.

The group is active in developing numerical approaches for this purpose using finite difference, finite volume or finite element discretizations, Lagrangian markers and multigrid solvers. We own a substantial proportion (1008 cores) of ETH's parallel cluster, Brutus.
