Expert in modeling, simulation, optimization, and failure prediction of structures and materials

Profile Summary

My research expertise in developing physics-based methodologies for computational modeling of material and structural failure. My current research focus areas are: (1) stochastic modeling of composite microstructure and failure, (2) ballistic failure of armor materials, (3) design of tough 3D-printable ceramic structures, (4) finite element modeling and failure prediction, (5) linking manufacturing methods with structural device failure in nonlinear materials and structures, and (6) coupling artificial intelligence with cellular automata to create optimized bio-like composite microstructures.
