Bibliography

Hello there!
I’m a Ph.D. student in Computer Science at the Hong Kong University of Science and Technology (HKUST) starting from 2024, advised by Prof. Yangqiu Song. Prior to that, I obtained two bachelor’s degrees in Computer Science and General Business Management from the Dual Degree Program at the same institution with the highest distinction.

Research Interests

I am generally interested in Natural Language Processing and Machine Learning. During my undergraduate studies, I worked on logical reasoning over both natural language and structured data with neuro-symbolic approaches.
My recent research interest mainly includes:

  • Explainable and Scalable System II Reasoning in LLMs
  • Logical Inference: Deduction, Induction and Abduction
  • Machine Theory-of-Mind

Awards

  • Hong Kong PhD Fellowship 2024
  • HKUST RedBird PhD Scholarship 2024
  • HKUST Academic Achievement Medal (~top 1% graduate)
  • HKUST Dean's Lists (8 semesters)
