About
I am currently working at Kuaishou, Beijing, China focusing on large language models for recommender systems (LLM4Rec). I received my Ph.D. in Computer Science and Technology in Tongji University (TJU), Shanghai, China and The Hong Kong Polytechnic University (PolyU), Hong Kong SAR. under the supervision of Prof. Jiannong Cao and Prof. Jihong Guan. From April to November 2025, I was a visiting scholar at the University of Illinois Chicago (UIC), Chicago, USA, advised by Prof. Philip S. Yu.
My research interests include data mining, LLM4Rec, and Agentic System. I am always open to research discussions and collaborations. Please feel free to contact me.
