I just fortunately joined the CS Ph.D. program at UC Berkeley RISELab in the fall, 2020.

Before coming to Berkeley, I was an undergraduate student majoring in computer science at Shanghai Jiao Tong University (SJTU) and a member of the SJTU ACM Honors Class.

I also had a wonderful time as a research assistant working with Prof. Song Han at MIT HAN Lab, and an undergraduate researcher working with Prof. Kai Yu and Prof. Yanmin Qian at SJTU SpeechLab.

My research interests lie in efficient deep learning, especially for natural language processing and speech, and system.
