Biography
Dr. Jiajun Liu is a Principal Research Scientist and Science Leader for the Distributed Sensing Systems Group. He also leads the Distributed Intelligence team in the group. He also co-leads research Theme 2: Safe AI in the real world at Responsible AI Research Centre, a joint research centre by CSIRO and University of Adelaide. He holds an Adjunct Associate Professor position at the University of Queensland.
He received his PhD/BEng from the University of Queensland, Australia, and Nanjing University, China, in 2013 and 2006, respectively. He worked as an Associate Professor in AI with the Renmin University of China before joining CSIRO, and co-founded a start-up that developed AI-driven software systems and solutions for major banks, e-commerce platforms, etc. From 2006 to 2008, he also worked as a Researcher/Software Engineer with IBM China Research/ Development Labs on supercomputing.
His research mainly focuses on Machine Learning and Data Science, in particular Efficient Deep Learning Methods, Physical AI, and Sensing Systems. At CSIRO he is looking into how to make neural nets and learning methods more efficient, make sensing systems more intelligent, and enabling emerging sensing technologies using Machine Learning/ Artificial Intelligence. Specifically, his research interest covers knowledge distillation, efficient design and structural pruning of neural architecture, optimising and operationalising efficient AI models on embodied agents, edge devices and distributed sensing applications.
He has served in the following conferences: Organiser, Embodied Multimodal Reasoning in Physical Environments Workshop@ECCV 2026; Area Chair, NeurIPS 26’; Senior PC member, WWW 26’; Industrial Program Chair, DICTA 25’; Session Chair VLDB 21’, and as Associate Editor for Springer Nature Computer Science Journal during 2024-2025. He also serves as a PC member for numerous ML/AI and sensing conferences including NeurIPS , ICLR, ICML, CVPR, ICCV, ECCV, AAAI, IJCAI, IPSN, etc.
He has supervised/co-supervised numerous PhD students, including:
- Guoping Zhao, Renmin University of China
- Yudong Chen, the University of Queensland
- Haodong Hong
- Vatsal Patel, Deakin University (drop out), Best Student Paper Award@ADMA 2022
- Yi Zhang, the University of Queensland, Best Student Paper Award@PAKDD2024
- Xuwei Xu
- Biprodip Pal, Griffith University, HDR Award of Excellence in a Research Thesis
His current PhD students include:
- Bingqing Zhang, the University of Queensland
- Anju Venunadha Karnavar, Griffith University
- Xunyi Zhao, Adelaide University
- Xiaoyu Zhang, RMIT
At CSIRO, he's been actively working on delivery impact into key challenges including conservation of our natural environment and biodiversity[1],[2],[3], and agriculture. He is the lead inventor/co-inventor for multiple international patents [1],[2]. He was the recipient of the CSIRO Collaboration Award 2022.
