Dr. Park's research is centered at discovering new optical phenomena and applications using nanoscale materials and structures and has currently three major thrusts: nonlinear optical devices, biosensing/therapeutics and magnetic field sensor. For nonlinear optical devices, Dr. Park is developing devices based on chalcogenide glass for operations in the infrared region for sensing, communications, and switching. For biosensing and therapeutics, Dr. Park is developing nanomaterials that efficiently upconvert frequencies and thereby enable new imaging, sensing and/or therapeutic approaches. For magnetic field sensing, Dr. Park is developing magneto-optical nanomaterials that can rotate light polarization under a magnetic field with potential application in magnetic imaging.
