Hello, this is Junliang Yu. I am currently an ARC DECRA Research Fellow in the Data Science discipline at The University of Queensland (UQ). Prior to this, I worked as a postdoctoral research fellow with Prof. Shazia Sadiq, and completed my PhD at UQ in 2023 under the supervision of Prof. Hongzhi Yin. Before joining UQ, I obtained my M.Sc. and B.E. degrees from Chongqing University, where I was advised by Prof. Min Gao.

My research focuses on developing reliable and reproducible methods in recommender systems and data science. As of March 2025, my publications have been cited over 4,000 times. Several of my 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. I have also delivered four tutorials about recommender systems and graph machine learning at top-tier conferences, contributing to community knowledge-sharing and collaboration. In addition, I am committed to open-source development, and have created two recommender system toolkits, QRec and SELFRec, which are actively used by researchers and practitioners.

Research Interests

One fully funded PhD scholarships is available ~~. One for an international student and one~~ for a domestic student, with flexible enrolment in 2025. The PhD candidates will be co-supervised by me and Prof. Hongzhi Yin (associate supervisor). If you are interested in recommender systems and data science, please feel free to drop me an email and apply.
