Junliang Yu is currently an ARC DECRA Research Fellow in the Data Science discipline at The University of Queensland (UQ), and will be joining Griffith University as a Lecturer (equivalent to U.S. Assistant Professor) in Spring 2026. Prior to this, he worked as a postdoctoral research fellow with Prof. Shazia Sadiq. He completed his PhD at UQ in 2023 under the supervision of Prof. Hongzhi Yin. Before joining UQ, he obtained his M.Sc. and B.E. degrees from Chongqing University, where he was advised by Prof. Min Gao.

His research interests include recommender systems, graph learning, generative AI, and multi-agent systems. As of September 2025, his publications have received over 5,000 citations. Several of his works have been recognised as The Most Influential Papers by Paper Digest, and three journal articles have been listed as ESI Hot / Highly Cited Papers. He has delivered four tutorials on recommender systems and graph machine learning at top-tier international conferences, contributing to community knowledge-sharing and collaboration. In addition, he is committed to open-source research and has developed two recommender system toolkits, QRec and SELFRec, which are actively used by researchers and practitioners.
