His work includes the first nanoimprint-fabricated optical negative index meta-material at 1.55 micron range, the first optical modulation using negative index meta-material at near-IR, the first third harmonic generation using meta-material, crossbar memory (i.e. memristor) and logic circuits with the record high densities, highly sensitive surface enhanced Raman sensors fabricated using 3-D nanoimprint, the first room-temperature working single electron memory and the first large area bit-patterned magnetic media fabricated using nanoimprint. The nanoimprint machine he invented has been commercialized via IP licensing. He coauthored 71 peer reviewed journal papers and more than 60 conference presentations, including 13 keynote and invited presentations. He has 58 granted US patents and 57 pending applications.
