[Curriculum Vitae]

General

I am a PhD candidate at Johns Hopkins University and expect to graduate in March 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, improving controllability, robustness and multimodal learning. Moreover, I have conducted research or held internship positions at leading companies including Meta, Microsoft, Tencent, Amazon, and Zoom.
