Welcome to the homepage of the UW Radiological Engineering and Design (RED) Lab! The mission of the RED Lab is to advance the beneficial uses of ionizing radiation for cancer treatment. Together with both clinical and industrial partners, the RED Lab identifies future challenges that will likely impede the quality and effectiveness of cancer care to patients. We aim to introduce disruptive ideas and translational technology that will help address these challenges through the use of computational modeling and simulation and instrumentation design and development. While much of our attention is devoted to the advancement of radiation therapy, the laboratory also addresses problems encountered in imaging, immunotherapy, and surgery.
