Research: Processing-microstructure-mechanical property relationships in metallic materials, i.e. nanocrystalline materials (copper, stainless steel, nickel titanium, titanium alloys), conventional and magnetic shape memory alloys (NiTi, NiTiHf, FeNiCoTi, FeMnSiCrNi, CoNiAl, CoNiGa, NiMnGa), bulk metallic glasses and composites; micro-mechanical constitutive modeling of crystal plasticity; twinning and martensitic phase transformation in metallic materials, magnetic, thermal and mechanical activation of martensitic phase transformation. Unique processing methodologies used are single crystal growth and equal channel angular extrusion.
Teaching: Texture and Anisotropy in Materials, Nanoscale Issues in Manfacturing, Mechanical Behavior of Materials, Materials and Manufacturing Selection in Design, and Fundamentals of Materials Science and Engineering.
