I am a Sr. Research Scientist at NVIDIA working on near-eye displays and holographic displays for AR/VR applications. I was previously a Visiting Scholar at Stanford University in the Computational Imaging lab with Prof. Gordon Wetzstein.
I received my Ph.D in Electrical and Computer Engineering from Seoul National University in 2017 where I was advised by Prof. Byoungho Lee, and my Bachelor’s degree in Electrical Engineering from Seoul National University in 2011.
My research interests include Near-eye Displays, Holographic Displays, Light Field Displays, and Computational Displays.
