Research

My research is in Computational Fracture Mechanics with a special interest in extended finite element methods (XFEM), damage/phase field methods, cohesive zone methods, multigrid/multiscale methods, inverse optimization problems, mixed finite element formulations and scientific/parallel computing.

I have been engaged in diverse applications with different physics at a wide range of temporal and spatial scales, e.g. high strain rates impact problems in metals, delamination of composite materials, damage in suspension bridges and concrete structures, and fracture of ice sheets in polar regions.
