I am currently a Ph.D. candidate majoring in artificial intelligence at the School of Artificial Intelligence, Jilin University (985, 211, Double 1st-Class), supervised by Prof. Hechang Chen. My research interests lie in the fields of graph data mining, large language models, reinforcement learning, and embodied AI.
