My research interests are connected to defect modelling in solid materials. This encompasses damage-based fracture in elastic and elasto/plastic materials, and dislocation and disclinations modelling in single crystals.

The mathematical tools used and developed for this purposes are variational methods, differential geometry and topological sensitivity analysis. Linear and nonlinear elasticity, plasticity, Continuum mechanics and thermodynamics are investigated to develop these models.

Theoretical and numerical results are sought.
