Ruitong Liu
Welcome to my homepage!
I am currently a senior majoring at Dalian University of Technology. I will start my graduate studies at the School of Mathematical Sciences, Peking University in September 2026. My research focuses on Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs), covering large-scale data engineering, complex reasoning optimization, training algorithms and full-stack training, KG+LLM, and mathematical formal reasoning. I am currently also working on research related to World Models(WMs).
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!
