About Me

I am a Ph.D. student in the Department of Electronic Engineering at The Chinese University of Hong Kong (CUHK), advised by Prof. Wing-Kin Ma. I am a member of the DSP & Speech Technology Laboratory.

Before joining CUHK, I received my B.Eng. and M.Eng. degrees in Communication Engineering from Northwestern Polytechnical University (NWPU) in 2021 and 2024, respectively.

Research Interests
