About me ⛵

My PhD journey takes me to Nanyang Technological University (NTU), where I am honored to conduct research funded and supervised by Prof. Jie Zhang.

I received my Bachelor’s degree in Data Science and Big Data Technology from Harbin Institute of Technology, Shenzhen (HITsz)（哈尔滨工业大学 深圳） in June 2025 (GPA 91.86/100, Rank 10/172, National Scholarship *1).

During my undergraduate studies, it was my great honor to receive the guidance from Prof. Jianghong Ma, Prof. Shanshan Feng at HITsz, and Prof. Sibo Wang at CUHK. I also worked as a research intern at Tencent Weixin Group (WXG), Shenzhen from Sep. 2024 to Jun. 2025, where I was luckily guided by Yuanhao Feng, Dr. Guilin Li, and Bo Wang.

Research areas 🔬

At present, my research centers on the intersection between Large Models and Recommender Systems. My broader research interests also include

  • Multimodal Chain-of-Thoughts for Visual Question Answering
  • Graph Learning (e.g., GNN-based Recommendations and Graph Anomaly Detection)
