About Me

I am a third-year PhD student at the Chinese University of Hong Kong, supervised by Prof. Xunying Liu. Before that, I finished my master’s degree under the supervision of Prof. Zhen Wang at Northwestern Polytechnical University, where I also obtained my bachelor’s degree. My research interests lie in automatic speech recognition, machine leaning, and model compression. I am currently focusing on developing lightweight and efficient deep learning systems.
