I am an Assistant Professor in Department of Applied Mathematics, The Hong Kong Polytechnic University. I also serve as an Assistant Director of Research Center for Intelligent Operations Research and an Associate Director (Research and Development Management) of CITIC-PolyU Interdisciplinary Mathematical Digital AI Joint Laboratory (AIJLab). I was an Assistant Professor (2024.07 – 2025.02) in Department of Data Science and Artificial Intelligence. Before joining PolyU, I was a research fellow in NExT Research Center , School of Computing, National University of Singapore, working with Prof. Tat-Seng CHUA.
I obtained my PhD in Mathematics, from Department of Mathematics, National University of Singapore in 2020. My Ph.D supervisor is Prof. Kim-Chuan TOH. I was fortunately supervised by Prof. Defeng SUN from 2015 to 2018. Prior to NUS, I obtained my Bachelor’s degree in Computational Mathematics from University of Science and Technology of China (USTC) in 2015, where I was supervised by Prof. Juyong ZHANG.
