Dr Hongfu Sun is a Senior Lecturer in Biomedical Engineering at the University of Newcastle and an Honorary Senior Research Fellow at the University of Queensland. His research focuses on quantitative MRI, computational imaging, and physics-informed artificial intelligence for next-generation medical imaging technologies.

Dr Sun has made internationally recognised contributions to Quantitative Susceptibility Mapping (QSM), helping transform MRI phase information into quantitative measurements of tissue properties. His work spans MRI physics, signal processing, and machine learning, with the goal of improving the reliability and accessibility of quantitative imaging.

He currently leads research on AI-driven quantitative MRI reconstruction, ultra-low-field portable MRI, and advanced relaxometry methods. These approaches aim to enable robust imaging from noisy, incomplete, or hardware-constrained data, with applications ranging from brain imaging to emerging portable MRI technologies.

Dr Sun is the recipient of an Australian Research Council (ARC) Discovery Early Career Researcher Award (DECRA). He has authored numerous peer-reviewed publications in leading MRI and medical imaging journals and collaborates with researchers across Australia, North America, and Europe.

Beyond research, Dr Sun is actively involved in teaching and mentoring engineering students and developing interdisciplinary collaborations in medical imaging, biomedical engineering, and AI.
