I am interested in soft matter materials (polymers, composite materials, colloids, bitumen, molecular crystals…) and their interfaces. I study them from a numerical and theoretical point of view, using computer simulations (classical molecular dynamics, dissipative particle dynamics and kinetic Monte-Carlo) and tools from statistical physics, thermodynamics, chemical kinetics and rheology. I am particularly interested in multiscale approaches from the classical atomic description up to mesoscopic and continuum mechanics scales. Thus, I often investigate the link between structural properties (radial distribution function, molecule size, aggregate size, …) and thermodynamic (enthalpy, cohesion energy, surface tension, …), mechanical (pressure, stress and strain tensors, …) and transport (viscosity, diffusion coefficient, viscoelastic relaxation coefficients, …) properties. More recently, I have been researching these relationships in materials under shock loading.
