Research interests

My current research focuses on agentic systems for enterprise data analytics, centered on QwenPaw-Data: building data agents that ground ambiguous business concepts in trustworthy semantics, codify reusable analytical methodology, and execute long-horizon workflows with controllable, artifact-centric runtimes. More broadly, I work on data agents, LLM–database systems (e.g., Text-to-SQL and LLM-enhanced relational operators), and AI for databases (AI4DB).
