Zhirui Chen
I am currently a final-year PhD student at the Department of Industrial Systems Engineering and Management, National University of Singapore (NUS), where I am fortunately advised by Prof. Vincent Y. F. Tan and Prof. Yeow Meng Chee. Previously, I received the B.Eng. degree from the School of Data and Computer Science, Sun Yat-sen University, China, in 2017.
My research interests focus on reinforcement learning, differential privacy and large language models. Additionally, I have professional programming experience from my two-year career as a software engineer at Tencent and winning four gold medals in the ICPC Asia Regional Contest.
