General

I am a PhD student at The Chinese University of Hongkong, majoring in Speech and Audio Processing, Supervised by Prof. Helen Meng. Before that, I received the Master's Degree from Peking University in 2023.

My research focus on developing a human-agent that can communicate with human, e.g. understooding human's speech and environments sound, and then producing feedback to humans.
Note: I am actively looking for any collaboration opportunities (e.g. Audio Foundation Models, Generative Models, TTS, Text-to-audio...). Please feel free to contact me.

Research Interests

Audio Foundation Models, Generative Models, Large Language Models, Audio/Speech Processing
