Function and Responsibilities:

Head of Helmholtz Young Investigators Group CRYSTALS.

Supervision of 4 postdocs and 4 students.

For more info see the CRYSTALS homepage.

Research Interests:

My general scientific interests comprise lithosphere dynamics, natural hazards, plate tectonics, climate and their intricate links. My current main focus lies on the dynamics of rifting and continental breakup across the scales: from the localisation of faults and shear zones to lithospheric necking and the interaction with mantle convection and large-scale plate tectonics. To study these processes, I use a diverse set of modelling tools and integrate observations from structural geology, geophysical imaging, rheology, and plate reconstructions.
