Research

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. 

Current projects :
• Deformation processes of lateral slab tearing, from crust to mantle, ITN SUBITOP
• Role of overriding plate rheology on subduction dynamics
• Subduction dynamics in Patagonia
• Dynamic topography around the proto-Paratethys
