I am a first-year PhD student in Data Science and Engineering at East China Normal University (ECNU), supervised by Prof. Xuesong Lu. Currently, I am a visiting scholar at The Hong Kong University of Science and Technology (Guangzhou) (HKUST-GZ), supervised by Prof. Zhijiang Guo.
My research interests lie at the intersection of natural language processing (NLP), LLMs, international Chinese education and Agents. Previously, I explored topics related to Chinese language learning and NLP applications in education. Currently, my primary focus is on LLM as a judge, investigating its potential for evaluation and decision-making in various contexts.
