My name is Yuxia Wu, a research scientist at Singapore Management University (SMU), working with Assistant Prof. Yuan Fang. I also closely collaborate with Assistant Prof. Lizi Liao. Previously, I obtained my Ph.D. degree in the area of Computer Science at SMILES lab, Xi’an Jiaotong University, advised by Prof. Xueming Qian.

Research interests:

• Recommendation System: Sequential recommendation; Conversational recommendation; Explainable recommendation
• Conversational System: Task-oriented dialog system; Conversational understanding
• Graph Data Mining: Dynamic graph modeling; LLM for graphs
• Spatial-Temporal: Human mobility; Smart cities; Temporal event forecasting
