[Curriculum Vitae]

General

I am a second-year PhD student at Johns Hopkins University, working on speech and audio processing. Before that, I received my Bachelor's Degree from Tsinghua University in 2019 and my Master's Degree from Peking University in 2022.
(Note: I am actively looking for any collaboration opportunities. Please feel free to contact me.)
