Postdoctoral Scholars

Gwangwoo Kim

Gwangwoo is a Postdoctoral Researcher at the University of Pennsylvania. He obtained his PhD in Energy Engineering at Ulsan National Institute of Science and Technology, South Korea in 2019. During his PhD course, he studied the physicochemical properties of hexagonal boron nitride and its in-plane heterostructures with graphene, and explored the applicability of the heterostructures as optoelectronic devices, under the supervision of Prof. Hyeon Suk Shin. His research at Penn focuses on growth of atomically thin chalcogenide quantum dots for tunable quantum-optoelectronics.
