I am a Foundation Model Algorithm Engineer at ModelBest (面壁智能，VoxCPM). I received my Master's degree from the School of Artificial Intelligence, Beijing University of Posts and Telecommunications (BUPT). My research interests lie in the intersection of Large Speech Models (LSM), Automatic Speech Recognition (ASR), Singing Voice Conversion (SVC), and Expressive Text-to-Speech (TTS).

Prior to joining ModelBest, I earned my Bachelor's degree in Computer Science and Technology from Ningbo University (Yangming Innovation Class). I have gained extensive industry experience through research and engineering internships at Zhipu AI (智谱AI语音输入法), Tencent Music Entertainment (TME, Lyra Lab / 天琴实验室), and Momo (陌陌).

I have been awarded the Zhejiang Government Scholarship (3 times) and the BUPT First-Class Scholarship (2 times). My research has been accepted for top-tier conferences such as AAAI, Interspeech, ICASSP, and ISCSLP.
