I work on the relationships between processing, microstructure and properties of metallic materials: [1] Strengthening and toughening mechanisms; [2] Severe plastic deformation (SPD); [3] In situ characterization and quantitative evaluation of microstructures; [4] Physical and finite element simulation, modeling and plastic deformation mechanisms of high-performance metallic materials; [5] Additive manufacturing (3D Printing); [6] Novel materials design, development and processing techniques.
