I am a third-year Ph.D. candidate at Intelligent Information Retrieval Lab (IIR Lab) from the Gaoling School of Artificial Intelligence (GSAI), Renmin University of China (RUC), supervised by Prof. Jun Xu. I obtained my bachelor’s degree from Harbin Institute of Technology, Shenzhen (HITSZ) in June 2023. My research interests include Information Retrieval, GUI Agent, and Agentic Search.
