Short 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 deformtion of crust during tectonic events (i.e., orogeny) and crustal mechanics, and mass transport throughout the crust.
