Biography

I am a Ph.D. student in Computer Technology at the University of Science and Technology of China (USTC), advised by Prof. Xiangyang Li and Prof. Qi Song. My research focuses on knowledge-driven artificial intelligence, particularly knowledge graph construction and knowledge-enhanced large language models.

Research Interests

  • Knowledge Graph Construction and Information Extraction
  • Graph-Based Knowledge Grounding for Large Language Models
  • Reliable and Interpretable AI Systems
