I’m currently a PhD student at School of Computer Science and Engineering, University of Electronic Science and Technology of China, supervised by Prof. Kai Zheng. Previously, I received my B.E. degree from Chongqing University of Posts and Telecommunications in 2022.

My research interests include vector databases, AI4DB and spatio-temporal data management.
