Computer Science Undergraduate and Researcher

I am a fourth-year undergraduate in Computer Science and Engineering at The Chinese University of Hong Kong, Shenzhen. I am currently advised by Prof. Chenhao Tan (Chicago Human + AI Lab, University of Chicago) and Prof. Benyou Wang (The Chinese University of Hong Kong, Shenzhen).

My research interests include natural language processing, LLM agents, human–AI interaction, AI for science, and operations research.

Selected Research

Self-Evolving Knowledge System Project Lead, 2026 – present

A human-in-the-loop framework for evolving domain-specific knowledge bases, supported by automated data generation and a RAG-based knowledge system.

Advised by Prof. Benyou Wang, The Chinese University of Hong Kong, Shenzhen.

LLMs for Scientific Ideation and Hypothesis Generation 2025

Explored heuristic-based ideation and hierarchical methods for automated scientific hypothesis generation at the Chicago Human + AI Lab.

Advised by Prof. Chenhao Tan, University of Chicago.

LLMs for Operations Research Modeling Project Lead, 2024

Designed and developed an autonomous operations research modeling agent with a bottom-up framework and a dedicated debugging solver group for reliable model formulation.

Advised by Prof. Ruoyu Sun, The Chinese University of Hong Kong, Shenzhen.

Selected Projects

Phoenix-Agent Project Lead, 2026

A hierarchical LLM-agent architecture in which a global orchestrator coordinates specialized search, coding, and analysis workflows. The system achieved 73.6% accuracy on GAIA Level 1 without task-specific fine-tuning and was deployed in a campus environment to integrate multiple university services.

AI Q&A Tutor Project Lead, 2026

A campus knowledge assistant for student questions, deployed at CUHK-Shenzhen to help students navigate university life and access campus information.

DualSight Co-leader, 2026

A vision-language GUI agent that parses screenshots into structured interface elements and selects actions from natural-language instructions.

Branch Coder Co-leader, 2025

A VS Code coding agent with workspace-aware RAG, semantic code indexing, MCP tools, and parallel execution workflows.

Chat with CUHKSZ 2024

A C++ campus agent integrating student services such as course schedules, grades, library resources, email, Blackboard content, venue booking, and email actions.
