👋 About Me

Hi~! I am a Rawlings Presidential Research Scholar at Cornell University 🐻 in College of Engineering, pursuing a B.S. in Computer Science with a minor in Mathematics. I am currently working as an undergraduate researcher in the Natural Language Processing Group at Cornell’s Computer Science Department, and I am honored to be supervised by Professor Tanya Goyal. I am involved in the Math + AI Lab at Cornell, and I also collaborate with the PI Lab at Tsinghua University.

🔬 Research Interests

My research focuses on:

• Natural Language Processing: Analyzing and improving reasoning-based Large Language Models
• LLM Evaluation: Meta-evaluation of automatic benchmarks and evaluators
• Multimodal Learning: Integrating vision and language for medical applications
• AI Agents and Tool: Intelligent AI tool platforms and agent systems
