PhD Student

National University of Singapore


I am a third-year PhD student in School of Engineering at National University of Singapore, supervised by Professor Andrew Lim. I received my B.E. degree from the School of Computer Science and Technology, Xidian University in 2018. While completing several innovative projects, I have also published several papers in recommended journals and conferences, such as TKDE, ACM MM and NeurIPS.

My research interests lie in graph neural networks, 3d point cloud and spatio-temporal data mining. If you are interested in my research, please feel free to contact me!
