We work on the multi-scale modeling of thermo-hydro-chemo-mechanical damage and healing processes, fracture pattern formation and coupled deformation mechanisms in geomaterials. Applications include geological storage (nuclear waste disposals, Compressed Air Energy Storage), mineral resource management (hydraulic fracturing, geothermal energy), aggregate technology (ballast), and infrastructure design (concrete reparation, subsurface structures).
We also seek synergies between mechanics and biology by modeling teeth and dentistry reparation techniques, simulating dynamic networks inspired by plants, designing bio-inspired burrowing methods and optimizing cavities based on animal intelligence.
