I am currently an MPhil student at The Hong Kong University of
Science and Technology (Guangzhou), advised by
Professor Zhijiang Guo.
Before that, I graduated from the University of Electronic Science
and Technology of China (UESTC).
My research focuses on building autonomous and continually
improving AI systems, with particular interests in agentic
intelligence, data agents, and foundation model training.
