Kort presentation
My research focuses on the dynamics of continental crust and its physical properties. I use a mix of field work, laboratory experiments and modelling, with target to better understand the deformation of crust during tectonic events (i.e., orogeny) and crustal mechanics, as well as mass transport throughout the crust.
