Description:

Background
The Ren Laboratory in the Department of Radiation Oncology at Northwestern University is seeking highly motivated Postdoctoral Fellows to join our AI research program focused on developing and translating cutting-edge artificial intelligence technologies for radiation therapy.

Research areas include the development and implementation of advanced AI techniques for image-guided radiation therapy, including image reconstruction, enhancement, synthesis, segmentation, and registration, as well as AI-driven approaches for treatment outcome prediction and clinical decision-making. Projects involve multimodality imaging data, including CT, MRI, PET, and Ultrasound, as well as clinical radiation oncology software platforms such as treatment planning and image guidance systems. The overarching goal of the research is to develop practical and clinically translatable AI technologies that directly improve patient care and outcomes in radiation oncology.

Dr. Ren will join Northwestern University in July. Additional information about his current research program can be found at:
