🧑🎓 Research Interests
I am a Ph.D. focusing on:
- Knowledge Tracing and Cognitive Diagnosis（知识追踪与认知诊断）
- Large Language Models in Education（教育大语言模型）
- Student Modeling and Learning Analytics（学生知识状态建模）
- Natural Language Processing（自然语言处理）
My work aims to bridge cognitive understanding with computational methods to support personalized and explainable educational technology.
