About
My research interests are in solid mechanics, material modeling, and numerical analysis. The research focuses on plastic deformation and fracture in metals, with a particular emphasis on micromechanical modeling. The work combines experiments, theory, and numerical modeling and simulation, and involves the use of experimental microstructure data to understand how the microstructure influences material behavior. Current projects address stochastic fracture behavior in cast aluminum and polymer-based metamaterials for energy absorption under impact loading. An overarching goal is to develop more accurate models for describing and predicting fracture in materials.
