About
My research activities are related to plastic flow and fracture in metal alloys. A particular focus is on micromechanics-based modeling strategies, aiming to increase our understanding of material behavior up to failure and improve current models for plasticity and ductile fracture of ductile solids. My scientific work involves characterizing and modeling material behavior through physical and virtual experiments and is based on combining experimental, theoretical, and numerical methods.
