About Me
I am a Lecturer with the Shandong Computer Science Center (National Supercomputer Center in Jinan) at Qilu University of Technology (Shandong Academy of Sciences). I received my doctoral degree from China University of Petroleum (East China), advised by Prof. Lianyong Qi ↗. My research focuses on recommender systems, particularly sequential and point-of-interest recommendation, multimodal recommendation, large language models for recommendation, and trustworthy and explainable recommendation.
I was selected for the CAST Young Elite Scientists Sponsorship Program for Doctoral Students in 2024. My research has received the IEEE ATC 2022 Best Paper Award and ESI Highly Cited and Hot Paper recognition. My publications include first-author, co-first-author and collaborative work in NeurIPS, SIGIR, AAAI, WWW, IJCAI, ACM Multimedia and leading journals.
