About Me
I am an AI researcher at the AWS AI Lab in New York and a founding member of the AWS Bedrock RAG and Agentic AI Science team. Before joining AWS, I obtained my Ph.D. in Computer Science Department at The Ohio State University, advised by Prof. Eric Fosler-Lussier. Prior to OSU, I obtained my B.S. at Fudan University, advised by Prof. Xipeng Qiu.
Research Interests
My research focuses on building robust and generalizable AI models and systems that interact with data and environments through natural language. My work spans several interconnected areas:
Natural Language Interfaces to Data: I develop methods for enabling natural language interaction with structured and semi-structured data, including text-to-SQL, table understanding, and database question answering. A significant focus of my work is on improving robustness and cross-domain generalization of these models and systems.
Retrieval-Augmented Generation (RAG): I develop advanced RAG solutions focusing on heterogeneous data retrieval, agentic retrieval, and diagnostic evaluation frameworks.
Agentic AI and Computer-Use Agents: I am actively working on building autonomous agents that interact with computer environments and orchestrate complex workflows. My recent work includes retrieval-augmented world models for agent planning and automated frameworks for composing agent systems.
Table Representation Learning: I work on instruction tuning for table understanding tasks and developing methods to improve model performance on structured data. I also co-organized the Table Representation Learning workshop at ACL 2025.
Robustness and Evaluation: A core theme across my research is developing diagnostic benchmarks and evaluation frameworks to systematically assess model capabilities and failure modes, enabling more reliable AI systems.

Miscs
In my spare time I enjoy tennis, painting (Summer Lake, Fall), dancing, and traveling. I’ve stayed in Tianjin, Shanghai, Taipei, Columbus, San Jose, New York, and Honolulu for more than one month.
