I am currently a Ph.D. candidate at the University of Chinese Academy of Sciences and the Institute of Information Engineering, Chinese Academy of Sciences, under the supervision of Prof. Songlin Hu. My research interests include natural language processing and machine learning, with a recent focus on representation learning theory, sentiment analysis, and trustworthy large language models. I achieved first place in four tasks at the SemEval competitions and received the Best System Award at SemEval-2023 in Task 12.

Research Interests

Representation Learning for NLP
- Learning theory & principle, generalization, robustness, transferability.
Sentiment Analysis
- Sentiment classification, emotion recognition, dimensional emotion analysis.
Trustworthy Large Language Models
- LLM-generated content moderation, LLM hallucination mitigation.
