Zhirui Chen, Ph.D.
I will be joining ByteDance Inc. as a research scientist soon. Prior to that, I was a postdoctoral research fellow at the Department of Electrical and Computer Engineering, National University of Singapore. I recently received the Ph.D. degree from the College of Design and Engineering, National University of Singapore, in March 2025, fortunately under the supervision of 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, in 2017.
My research interests focus on reinforcement learning 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 ICPC Asia.
