Junliang Yu is a Lecturer (Assistant Professor) and ARC DECRA Fellow in the School of Information and Communication Technology at Griffith University. Prior to joining Griffith, he was a Research Fellow in the Data Science discipline at The University of Queensland (UQ), where he also obtained his PhD in 2023 under the supervision of Prof. Hongzhi Yin. He previously received his M.Sc. and B.E. degrees from Chongqing University, advised by Prof. Min Gao.

His research focuses on recommender systems, data mining, generative AI, and agentic systems. His work has been widely published in leading venues in these areas and has received over 6,000 citations, placing him among the world’s top 2% scientists. He has also delivered four tutorials on recommender systems and graph machine learning at top-tier international conferences. In addition, he actively contributes to open research and has developed two open-source recommender system toolkits, QRec and SELFRec, which are widely used by the research community.
