About Me

I am currently a 4^th-year undergraduate student majoring in Data Science in Tongji University, and am an incoming PhD (2025 Fall) at School of Computing, National University of Singapore, supervised by Prof. Shuicheng Yan. I am also fortunate to work closely with Prof. Tianlong Chen, Prof. Shirui Pan, Prof. Dawei Cheng and Dr. Kun Wang.

Research Interests

Agentic AI: multi-agent communication & collaboration
Efficient AI: sparsity, model lightweighting, LLM pruning
Data-centric AI: data selection, data pruning, data cleaning
Data Mining: graph learning, spatio-temporal mining, graph sparsification
