About Me

I am currently a Ph.D. student in Data Science and Artificial Intelligence at The Hong Kong Polytechnic University, supervised by Prof. KC Tan. My research lies at the intersection of Reinforcement Learning and LLM Reasoning. More broadly, I am interested in Interpretability and Evolutionary Computation with RL (EC + RL).

I received my M.S. in Applied Statistics from Fudan University and my B.S. in Statistics from Sun Yat-sen University. I was fortunate to enjoy research experiences at Tencent AI Lab, advised by Dr. Haobo Fu, where I focused on Policy Diversity in RL; at ByteDance Seed, advised by Xiongcai Luo, where I worked on efficient reasoning and on-policy distillation; and at Amazon Web Services (AWS), advised by Tong He and Tianjun Xiao, where I worked on video object segmentation.

I am always happy to discuss research ideas around RL, LLM Reasoning, Interpretability, and EC + RL. Please feel free to contact me at nigelyaoj@gmail.com.
