## Research Interests
- Forward-looking fundamental research on Large Language Models, focusing on their design, computational properties, applications in real-world contexts, and transformative potential in scientific discovery.
- Development of practical and innovative frameworks to detect, diagnose, and mitigate hallucinations and reasoning limitations in LLMs, applicable across diverse modalities.
- Addressing educational challenges in an AI-driven future by fostering Renaissance-like thinking, achieving exceptional performance with AI tools, and strengthening core abilities without tool dependence—ultimately empowering individuals to surpass pre-AI capabilities. Developed [**LLM4LLM** Project](https://github.com/zzhang-cn/LLM4LLM/), an innovative curriculum using LLMs to explain their own mechanisms through interactive learning.
