Current• High-strain-rate behaviors of defects in metal and alloys - Derived a closed-form solution for the elastodynamic fields induced by defect evolution. - Designed a scientific computational algorithm to model the dynamic evolution of defects. - Investigated the mechanism of typical crack initiation near twin boundaries in Ni-based superalloys.• Development of a new characterization technique for defects in crystalline materials - Developed a data assimilation approach to solve the inverse problem of reconstructing internal defects evolutions from surface measurements. - Integrated multi-discipline techniques: discrete dislocation dynamics simulations from computational material science, ensemble variational methods from fluid mechanics, and total-variation minimization from image processing. - Implemented a GPU-accelerated optimization algorithm to speed up the reconstruction process.
