Research Interests

My existing research focuses on quality assurance and testing of graphical user interfaces (GUI), especially web GUI. I integrate traditional algorithms with deep learning models, large language models, and GUI agents to improve testing effectiveness.

My recent and future work focuses on GUI agents and agentic AI, with the goal of building practical and safe intelligent assistants. My work includes, but is not limited to: 1. Evaluation of agents under realistic usage scenarios; 2. Agents that are highly reliable, secure, and interpretable; 3. Agents that integrate GUI and CLI, as well as agents that combine cloud and edge environments.
