I am originally a field geologist working about the dynamics of accretionary prisms and subduction zones. I am particularly interested in the deformation localization processes, both in the brittle and the ductile field. In the past few years, I have developed competences in deformation experiments, to complement the observations of naturally deformed rocks. Some of my work is also devoted to the nature and role of fluids for deformation. My playground is mostly the Shimanto Belt in Japan, but some of my recent work is devoted to the Alps.

Some of the research topics I focus on:

1) Dynamics of accretionary prisms: I try to constrain the geometry of paleo-fluid circulation and paleo-fluid pressure field from the analysis of veins (microstructures, cathodoluminescence, microthermometry and isotope study of fluid inclusions) from the Shimanto Belt in Japan. In parallel, I use field data to define a large-scale tectonic framework to account for the Shimanto accretionary prism evolution since Cretaceous time.

2) Rheological properties of the shallow (z<40km) domain of subduction zones: I try to constrain experimentally, with the Paterson rig, the mechanical behavior of subducted sediments from the seafloor to the updip limit of the seismogenic zone. I also focused, using the Griggs apparatus, on the mechanical properties around the downdip limit of the seismogenic zone. In particular, I study the micro-processes responsible for the water weakening of quartz.
