I am currently start my third year of PhD in School of Data Science, The Chinese University of Hong Kong (Shenzhen). My chief supervisor is Prof. Satoshi Nakamura and co-supervisor is Prof. Haizhou Li. I completed my bachelor’s degree at the School Electronic and Information Engineering, Beihang University, And then I completed my master’s degree in Integrated Circuit Engineering from Tsinghua University, supervised by Prof. Shouyi Yin, in 2020. From 2020 to 2022, I worked as a speech algorithm engineer at Lenovo and Meituan.

My research interest includes speech-to-speech translation, speech-to-text translation, and speech generation. .
