Biography

I am a final-year Ph.D. student at Tsinghua University, advised by Prof. Yong Li and Prof. Jiansheng Chen. I'm interested in LLM Agents, World Models, MLLMs and Recommender Systems.

Previously, I received my B.E. degree from the Department of Electronic Engineering, Tsinghua University in June 2021. I also received the second B.E. degree from the School of Economics and Management, Tsinghua University in June 2021.

I have research experience on multimodal recommender systems, agentic recommender systems, LLM agent design, MLLMs, and world models. I am currently seeking industry job opportunities in these research areas with a 2026 graduation timeline.
