I'm currently a research intern (2026) at Vector Institute, focusing on trustworthy machine learning. Before that, I earned my B.Econ. in Economics and Mathematics from the China Economics and Management Academy at CUFE (Beijing, China, 2023; Playground), where I studied modeling human behavior at both micro and macro levels. To deepen my expertise in data-driven methods, I later joined the Department of Statistics for an M.S. in Statistics at UChicago (Chicago, IL, 2025; Playground), where I have been strengthening my theoretical foundations in machine learning and deep learning.

In my spare time, I enjoy yoga ๐Ÿง˜โ€โ™€๏ธ, tennis ๐ŸŽพ, arts ๐Ÿ–ผ๏ธ (painting, visual symbolism, exhibitions, etc.), and traveling ๐Ÿ—บ๏ธ.

Research Interest: AI Evaluation

Robust evaluation is essential for guiding the training of reliable systems. It not only measures system performance, but also seeks to understand system behavior and, most importantly, continuously refine alignment rubrics so they reflect rational human intentions and can be distilled into the evaluation process.

  • Static Evaluation: Design granular yet scalable metrics that capture richer task-specific properties and better match real design goals.
  • Human-in-the-Loop Evaluation: (1) Build representative feedback loops under limited budgets; (2) monitor bidirectional risks in human-AI interaction (e.g., humans: over-reliance, manipulation; AI: over-alignment, sycophancy) and develop collaboration paradigms that preserve rationality on both sides.
  • Interactive (Agentic) Evaluation: (1) Study the strengths and limits of foundational structures that emerge in agentic systems; (2) test the robustness of cooperative behaviors under adversarial conditions.

I'm especially interested in applying these ideas to AI safety and healthcare.
