About me

I am an assistant professor at the College of Computer Science and Technology, Jilin University. I am also an honorary visiting scholar at The Chinese University of Hong Kong, supervised by Prof. Irwin King. Prior to this position, I completed my Doctoral degree at Jilin University and earned a Joint Ph.D. degree from the City University of Hong Kong in 2024, under the supervision of Prof. Hongwei Zhao and Prof. Xiangyu Zhao. From Sep 2023 to Sep 2024, I was a research intern at Kuaishou Technology, working closely with Dr. Shuchang Liu and Dr. Qingpeng Cai.

🔥 The lab has several positions for master's and doctoral students every year. We also warmly welcome undergraduate research assistants to join us. The lab provides sufficient computing resources and financial support. Students interested in machine learning and data mining are welcome to join us. Please email me and attach your recent CV or other materials.

My research interests include:

• AI for Urban Application: Spatio-temporal data mining, time series analysis, urban region profiling, and intelligent traffic systems;

• Recommender Systems: LLM-enhanced recommendation, federated optimization, and multi-domain and multi-objective recommendation;
