About me

I am a PhD candidate in Computer Science at School of Computing (SoC), National University of Singapore (NUS), being supervised by Prof. Xiaokui Xiao and Prof. Bo Tang. I received my B.Eng. degree in Computer Science from Southern University of Science and Technology (SUSTech) in 2019. My research mainly revolves around large-scale networks, with a particular emphasis on random walk proximity computation, social influence analysis, and their practical applications. Link to my CV.
