Prof. Wang and his group are engaged in the research of magnetic nanotechnologies and information storage in general, including magnetic biochips, in vitro diagnostics, cell sorting, magnetic nanoparticles, nano-patterning, spin electronic materials and sensors, magnetic inductive heads, as well as magnetic integrated inductors and transformers. He uses modern thin-film growth techniques, lithography, and nanofabrication 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, spin-based information processing, efficient energy conversion and storage, and extremely high-density magnetic recording. His group conducts research in the Geballe Laboratory for Advanced Materials (GLAM), Stanford Nanofabrication Facility (SNF) and Stanford Nano Shared Facilities (SNSF), Center for Cancer Nanotechnology Excellence (CCNE) hosted at Stanford, and Stanford Cancer Institute. The Center for Magnetic Nanotechnology (formerly CRISM) he directs has close ties with the Information Storage Industry and co-sponsors The Magnetic Recording Conference (TMRC).
