Kyunghun Han (Assoc)

Kyunghun Han is a UMD Postdoctoral Researcher in the Microsystems and Nanotechnology Division. He received a B.S., Ph.D. in Electrical Engineering from Purdue University. His doctoral research was focused on chip-scale frequency comb generation with silicon nitride microresonator. He joined Samsung Electronics (Mechatronics R&D center) as a staff engineer where he studied wafer defect optical inspection and optical emission spectroscopy. Kyunghun Han is currently working with Vladimir Aksyuk developing integrated electro-optic modulator.
