About Me

Hello! This is Xiaotian. I am currently a Ph.D. student in the College of Information Science & Electronic Engineering at Zhejiang University, advised by Prof. Zuozhu Liu.

I received my bachelor's degree from Dalian University of Technology, where I was supervised by Prof. Risheng Liu. My current research interests lie in agent context management and generative models, with a particular focus on agent personalization and applications of video generative models. I am driven by a desire to pursue research directions that are both impactful and general. If you are seeking any form of cooperation, feel free to contact me.
