Hi! I’m Jiaqi Wei, a Ph.D. student at Zhejiang University, where I’m pursuing 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 Natural Language Processing (NLP), Large Language Models (LLM), and AI for Science (AI4Science). I’m always eager to connect with fellow researchers and practitioners in these fields. Feel free to reach out if you’d like to discuss potential collaborations or share ideas! Here is my WeChat.
