🎓About Me

I am a Research Fellow at the National University of Singapore, working with Prof. Tat-Seng Chua. I obtained my Ph.D from the Hefei University of Technology(HFUT), and supervised by Prof. Le Wu and Prof. Richang Hong. My research interests include data-centric recommendation(e.g., graph recommendation, LLM-based recommendation, and so on) and LLM safety(especially LLM alignment and reasoning safety). I have published several papers in leading journals and conferences, such as IEEE TKDE, IEEE TBD, KDD, SIGIR, ACM Multimedia, and IJCAI. If you are seeking any form of academic cooperation, please feel free to email me at yyh.hfut@gmail.com.
