[Curriculum Vitae]

General

I am a PhD candidate at Johns Hopkins University and expect to graduate in 2026. Before that, I received my Bachelor's Degree from Tsinghua University in 2019 and my Master's Degree from Peking University in 2022. My research interest majorly lies in AI for speech and audio signal processing, encompassing audio generation tasks such as source separation and text-to-speech synthesis, as well as audio understanding tasks like audio classification and captioning. Moreover, I have conducted research or held internship positions at leading companies including Meta, Microsoft, Tencent, Amazon, and Zoom.
(Note: I am actively looking for any industry opportunities. Please feel free to contact me.)
