Research team: Plasticity

Research

Modeling plasticity of minerals of the Earth's mantle. I study the mechanical properties, dislocations, grain boundaries and diffusion in complex materials such as ceramics and minerals, with atomic-scale simulations.

Teaching

Teachings at the Physics Department : Physics for 1st-year students - Physics for geologists - Thermodynamics - C programming

Codes developped
