Ph.D. Candidate · Tsinghua University
multimodal generation · world model
I am a Ph.D. candidate at the Department of Computer Science and Technology, Tsinghua University, advised by Prof. Huaping Liu and working closely with Dr. Feng Wang and Prof. Yikai Wang. Before Tsinghua, I completed my undergraduate studies at Xi'an Jiaotong University under Prof. Minnan Luo, focusing on knowledge graphs and their applications in natural language processing.
