Biosketch

Dr. Ren is a clinical medical physicist certified by ABR and a leading scientist in medical imaging and radiation therapy. His seminal research focuses on the image-guided radiation therapy (IGRT) and development and application of AI in radiation therapy.

Dr. Ren conducted some of the first studies on developing digital tomosynthesis (DTS) for fast, low-dose target localization in radiation therapy, which led to the development of the limited-angle intrafraction verification (LIVE) system for intrafraction verification in radiotherapy. His group also developed novel cone-beam CT (CBCT) scatter reduction and correction methods, DTS/CBCT/MRI image reconstruction methods using prior information and motion modeling, and 4D-CBCT sorting and reconstruction algorithms.

In recent years, Dr. Ren's group has focused on developing and implementing AI for radiation therapy applications. His research areas include developing novel AI, especially deep learning, techniques for deformable image registration, image synthesis, image reconstruction, image augmentation, 4D imaging, radiomics, clinical decision making, and digital phantom generation. They have been developing techniques to use deep learning and biomechanical modeling to generate on-board hybrid virtual-MRI/CBCT images to substantially improve the soft tissue contrast in CBCT for target localization in liver radiotherapy. In addition, his group is actively developing AI technologies for synthesizing highly realistic eXtended Modular ANthropomorphic (XMAN) phantoms for motion management and virtual clinical trials in radiation therapy. Recently, his group has been developing image reconstruction and processing techniques for novel imaging modalities such as prompt gamma imaging and protoaoustic imaging for proton dose verification.

The overall goal of Dr. Ren's research is to develop novel imaging and therapy technologies to improve the precision and outcome of radiation therapy treatments with high efficiency and minimal imaging dose. 

Dr. Ren's lab is actively seeking postdoc fellows. Please feel free to reach out if interested.
