I am an Assistant Professor in Department of Data Science and Artificial Intelligence, The Hong Kong Polytechnic University, since July 01, 2024. I also serve as an Assistant Director at Research Center for Intelligent Operations Research. I was an Assistant Professor (2023.04 – 2024.06) and a Research Assistant Professor (2021.04 – 2023.03) at Department of Applied Mathematics, The Hong Kong Polytechnic University. Before that. 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.
