About me

I am a Senior Audio Algorithm Engineer at OPPO, and formerly a Postdoctoral Researcher at the Institute of Acoustics, Chinese Academy of Sciences (2023.08 – 2026.03). My research lies in speech enhancement, end‑to‑end audio signal processing, deep learning for audio, and edge deployment of intelligent audio algorithms. I bridge academic innovation and industrial implementation, with proven experience in delivering audio algorithms for smartphone products.
