Ruitong Liu
Welcome to my homepage!
I am currently a master's student at the School of Mathematical Sciences, Peking University. My research primarily focuses on Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs), with particular interests in multimodal reasoning, reinforcement learning and alignment, AI agents, LLM knowledge editing, and formal reasoning. My current research centers on complex reasoning optimization, reinforcement learning framework design, LLM knowledge editing and augmentation, Lean4 prove, as well as reliable agent systems for real-world applications. I am also interested in World Models and am actively exploring this direction.
Now i am interning in Beijing. If you are interested in academic cooperation or exchanges in related fields, please feel free to contact me via email at any time!
