Dr. Wang is engaged in the research of magnetic nanotechnology, biosensors, spintronics, integrated inductors and information storage. He uses modern thin-film growth techniques and lithography to engineer new electromagnetic materials and devices and to study their behavior at nanoscale and at very high frequencies. His group is investigating magnetic nanoparticles, high saturation soft magnetic materials, giant magnetoresistance spin valves, magnetic tunnel junctions, and spin electronic materials, with applications in cancer nanotechnology, in vitro diagnostics, rapid radiation triage, spin-based information processing, efficient energy conversion and storage, and extremely high-density magnetic recording.
