I'm currently a second-year Ph.D. student under the supervision of Prof. Xiaowei Wu at the State Key Laboratory in the Internet of Things for Smart City (IOTSC), University of Macau. Prior to joining the Ph.D. program, I worked as a Research Assistant at IOTSC, also under the guidance of Prof. Wu. I received my Master's degree from Beijing Normal University and Bachelor's degree from Guangzhou University.
Research interest
I am broadly interested in algorithmic game theory and theoretical computer science. Currently, I mainly focus on fair allocation problems, particularly the existence of EFX allocations.
