About Me
I am currently a fourth-year Ph.D. candidate at the School of Computing, City University of Hong Kong, supervised by Dr. Chen Ma. My research focuses on Trustworthy Decisions, Data Valuation, and Large Language Models for Operations Research (LLMs for OR).
I received my M.S. degree in Software Engineering from the School of Computer Science and Engineering, Sun Yat-sen University, where I was supervised by Prof. Yubao Liu on graph-based sequential recommendation. I obtained my B.S. degree in Software Engineering from the Software College, Northeastern University, where my academic enlightenment advisor was Prof. Guibing Guo, and I followed him to work on explainable recommendation.
