Chou group has two primary missions: (i) explore innovative applications of nanotechnologies in information, energy, life science, and personal health by combining cutting-edge nanotechnology with frontier knowledge from different disciplines; and (ii) to develop new nanofabrication technologies that will fabricate structures substantially smaller, better, and cheaper than current technology permits.
Nanotechnology offers great opportunities for revolutionary advances in broad disciplines, because many conventional theories no longer apply in nanoscale.
Chou group’s current researches focus on three areas:  (1) nano-bioengineering, (2) nanophotonics, and (3) nanofabrication. Our previous works include nano-transistors and nano-magnetics.
Chou Group has laboratories of extensive equipment and facilities in nanobiology, nanophotonics, nanolectrontronics, nanomagnetics, and nanofabrication.
