I am currently a postdoctoral researcher at University at Buffalo, working with Prof. Jinjun Xiong and Prof. Venu Govindaraju. I received my PhD in Computer Science and Engineering from the Chinese University of Hong Kong (CUHK), under the supervision of Prof. Zili Shao. Previously, I received my B.Eng. from the University of Electronic Science and Technology of China (UESTC). I am interested in spatio-temporal data management, storage system, and cloud database.
