Présentation

My teaching activities are mainly given to students at the civil engineering department of the IUT de Saint Nazaire (Nantes University). I teach several subjects: mechanics of granular materials, geotechnics, structure mechanics, public works. I give also some courses about programming and computational methods to students of engineer, Master and PhD programs.

My research focus on mechanics of granular materials and the solid-fluid interaction in these materials. Here are my main research topics: - Discrete modeling and simulation of granular materials using the discrete element method (DEM) - Modeling of internal erosion in granular soils - Pore space characterization - Modeling of the fluid flow in saturated or unsaturated granular soils using DEM and lattice Boltzmann method (LBM) - Consequences of scalping and scalping/replacement procedures on mechanical properties of coarse-grained soils - Modeling of interactions between solid grains and fluid by coupling the DEM to SPH method (Smoothed Particle Hydrodynamics)
