Dr. Sifan Song is an Assistant Professor at Xi’an Jiaotong-Liverpool University. Prior to joining XJTLU, he served as a Research Fellow at Harvard Medical School and Massachusetts General Hospital (2024–2026), working with Dr. Quanzheng Li, Dr. Xiang Li, and Dr. Dufan Wu. His research focuses on representation learning, parameter-efficient fine-tuning, and explainable frameworks for large-scale natural and medical images, with an emphasis on 2D/3D segmentation and generation across CT, MRI, and PET, as well as efficient multimodal learning and the integration of large language models and multi-agent systems for real-world applications.

He received a PhD in Computer Science from the University of Liverpool. He also holds an MSc in Artificial Intelligence from the University of Southampton and an MSc in Bioinformatics from the University of Edinburgh. During his doctoral training, he was a visiting doctoral student with the MIRACLE team at the University of Science and Technology of China (2022–2024), working with Prof. Shaohua (Kevin) Zhou, and a visiting doctoral student at The Chinese University of Hong Kong (Shenzhen) (2019–2020), working with Dr. Jiaming Zhang.

He serves as a reviewer for npj Digital Medicine, IEEE Transactions on Medical Imaging, IEEE Transactions on Artificial Intelligence, Medical Physics, and regularly reviews for conferences such as AAAI, CVPR, ICLR, NeurIPS, MICCAI, ECCV, WACV, and ISBI. Dr. Song has experience collaborating with GE HealthCare and other medical AI industry partners on medical imaging AI research projects. His work aims to bridge advanced AI methodologies with real-world problems and interdisciplinary education.
