Dr. Park's research is centered at discovering new optical phenomena and applications using nanoscale materials and structures and has currently three major thrusts: energy harvesting, nonlinear optical devices and nanomedicine. For energy harvesting, Dr. Park is developing a new type of photovoltaic devices that can efficiently convert heat into electricity by using novel nanostructures. Dr. Park is also developing nonlinear devices operating in the mid-infrared region for sensing, communications, and switching. Finally, Dr. Park is developing multifunctional nanoclusters that can enable a new imaging and therapeutic approach for bladder cancer. This technology allows for cellular level detection and targeted treatment of bladder cancer.
