About Me

I’m a Ph.D. candidate at Semiconductor System Lab (SSL) at KAIST, advised by Prof. Hoi-Jun Yoo.
I received the B.S. and M.S. degrees from the School of Electrical Engineering at KAIST in 2020 and 2022, respectively.

Research Interests

My current research interests include energy-efficient System-on-Chip design, especially focused on AI-powered AR/VR and 3D vision systems. Over the past 4 years, I have participated in the design of 3 silicon chips related to artificial intelligence.

Neural Graphics Acceleration: ISSCC’23, ASSCC’23, ISSCC’24
3D Vision System: ISSCC’22
AR/VR System-on-Chip: IEDM’21
DNN Accelerator: JSSC’21, HPCA’23
