Chenlu Ye

Hi! My name is Chenlu Ye (叶晨璐).

I am a Ph.D. student at UIUC, advised by Prof. Tong Zhang. Previously, I received my MPhil from HKUST and B.S. from USTC.

My research interests lie at the intersection of reinforcement learning and large language model post-training. Recently, I focus on RL for reasoning and post-training of LLMs.
