Wissenschaftliche Interessen:

Scientific interests:

Developing innovative multidisciplinary approaches linking the dynamics of the Earth’s interior to a wide range of surface processes and observables (i.e., sedimentary basins dynamics, lithospheric deformation, multiphase heat-mass transfer, sedimentation, heat flow, GPS measurements, satellite and seismic data, etc.).

Developing numerical codes for the thermo-mechanical modeling of the Earth dynamics and surface processes acounting for the non-linear visco-elasto-plastic rheology, magma transport, surface erosion, fluid filtration, and free surface.

Expertise:

Tectonic deformations and crustal mass flux, lithospheric thermal state analysis, rheology, interaction between the deep-mantle and surface processes, seismicity, long- and short-term lithospheric stress state analysis.

Numerical models developing with the use of finite elements (FEM), finite differences (FDM), finite volumes (FVM) and spectral (SM) methods.
