📝 About Me

I have been with Guangzhou University since September 2023. Before joining GZHU, I worked as a software engineer at Gauss. I obtained my PhD from Department of Systems Engineering and Engineering Management, Chinese University of Hong Kong, proudly under the supervision of Prof. Jeffrey Xu Yu. My research is focused on graph algorithms and incremental computation.
