Hi, I am a final-year PhD candidate at The Chinese University of Hong Kong, advised by Prof. Wai Lam. My research focuses on natural language processing and large language models. More recently, I have been working at Qwen on pre-training and mid-training of LLMs.

During my PhD, I have conducted research at Shanghai AI Lab, Tencent AI Lab, and Alibaba DAMO Academy. Prior to starting my PhD, I worked as a research assistant under the supervision of Prof. Yue Zhang. I received my bachelor’s degree from Xi’an Jiaotong University.
