I am a Ph.D. Student in Computer Science at Virginia Tech (VT) starting in Fall 2023, advised by Prof. Chang-Tien Lu. Prior to VT, I obtained my bachelor's degree from Beijing Jiaotong University (BJTU) and master's degree from University of Chinese Academy of Sciences(UCAS). I spent one year working at Tencent as a machine learning engineer.

My research interests are NLP, LLMs, especially focusing on LLM trustworthiness and complex reasoning. It involves tool usage, uncertainty estimation, and LLM post-training.

Beyond my academic work, I enjoy photography, especially nature and birds.
