I am a second-year master student at IIGroup in Tsinghua University, supervised by Prof. Yujiu Yang. I received my Bachelor's degree at Computer Science and Technology, Harbin Institute of Technology, Shenzhen. Previously, I was honoured to work with Prof. Wenjie Pei in HITsz. I am currently working closely with Ruilin Luo, Shuoshuo Zhang and Yang Ding at THU. I will be graduating in Fall 2027 and am actively seeking job opportunities. Feel free to reach out!

My current research focuses on the post-training of Large Language Models (LLMs) and Multimodal LLMs (MLLMs), spanning Reinforcement Learning (RL) and On-Policy Distillation (OPD). I am broadly interested in a range of topics including reasoning enhancement, long-horizon tasks, alignment of Models, and pushing the boundaries of (M)LLMs to unlock their full potential in complex real-world scenarios. |
