Compétences

Mechanics of crystal defects and material properties: My research is focused on the microscale defects of the crystalline lattice (dislocations, disclinations, point defects, grain boundaries, interphases) and on how their interactions and self-organization influence the mechanical properties of the material at macroscale.
