I’m currently a PhD student in the second year 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 spatial-temporal data mining, high-dimensional vector approximate nearest neighbor search and spatial crowdsourcing.
