I am assistant professor in tectonics and geodynamics at the University of Rennes 1 since 2012. My research focus on the dynamics of subduction zones with an approach coupling field and remote data (structural geology, geomorphology, thermochronology) and analogue/numerical modeling. My main field targets are the South America and the Mediterranean. 

Active and recent projects :
• Interactions between subduction-induced and remotely-induced mantle flow from analogue/numerical modelling

• Exhumation history and erosion distribution constrained by detrital thermochronology on glacial deposits

• Transport of particles by glaciers from analogue modelling

• Tectonic reactivation of extensional basins from analogue modelling

• Role of plate age and upper plate kinematics on slab morphology from numerical modelling

• Deformation processes of lateral slab tearing, from crust to mantle

• Role of overriding plate rheology on subduction dynamics
