About Me

I am currently a joint Ph.D. student in Data Science at USTC and CityU, supervised by Prof. Enhong Chen and Prof. Tong Xu at BDAA Lab, and Prof. Xiangyu Zhao at AML Lab. Prior to starting my doctoral studies, I received my B.S. degree in Intelligent Science and Technology from XDU in 2021.

My research interests include Agent Memory, Retrieval-Augmented Generation, Knowledge Graphs, and Multimodal Learning.
