I’m currently a postdoctoral researcher at Max Planck Institute for Informatics. I obtained my PhD degree in Computer Science at The University of Hong Kong, where I was very fortunate to be supervised by Prof. Zhiyi Huang. Before that I obtained my bachelor’s degree from Yao Class, Tsinghua University, instructed by Prof. Ran Duan. I’m currently interested in online algorithms, algorithmic game theory and fundamental graph algorithms.
