Hi! I am a second-year Master student at Institute of Computing Technology, Chinese Academy of Sciences, supervised by Prof. Huawei Shen and Prof. Bingbing Xu. My current research interests include Search Engine, Recommender System, Reward Modeling, graph neural networks (GNNs), multi-agent in social simulation and LLM alignment. Before joining ICT, I received my bachelor’s degree from School of Mathematical Sciences , Tiangong University in 2023.
