I am currently a PhD student in the Electronic and Computer Engineering department of Hong Kong University of Science and Technology, AI Chip Center for Emerging Smart Systems, and a member of Vision and System Design Lab (VSDL) under the supervision of Prof. Kwang-Ting CHENG. I obtained my BEng degree in Microelectronic Science and Engineering from Southern University of Science and Technology in 2022, advised by Prof. Fengwei An. My research realm focuses on computer vision, model compression, AI chip, computer architecture, and software-hardware co-design. You can find more information through my CV. Welcome to contact with me if you have any interests.
