About

Hi there! I'm Jiaqi Wei, a Ph.D. student at Zhejiang University, where I conduct my research under the excellent guidance of Prof. Siqi Sun and Prof. Wanli Ouyang. Before beginning my doctoral studies here, I completed my B.E. degree in Computer Science at Shandong University (GPA: 93.83/100.00; Rank 1st).

My core research interests lie at the fascinating intersection of LLM, Agent and RAG. Feel free to reach out if you'd like to discuss potential collaborations or share ideas.
