About
I am a first-year PhD student at the Gaoling School of Artificial Intelligence (GSAI), Renmin University of China (RUC), supervised by Prof. Zhicheng Dou. I received my bachelor’s degree from RUC in 2025.
My recent research focuses on long-horizon agents, including self-evolving agents, agent memory, and AutoResearch agents that can adapt, accumulate experience, and improve through extended interaction.
I am currently a research intern at the Information Retrieval and Knowledge Computing Group at the Beijing Academy of Artificial Intelligence (BAAI), where I work with Postdoctoral Researcher Hongjin Qian under the supervision of Prof. Zheng Liu.
Feel free to contact me if you are interested in related topics or potential collaborations!
