Radiation Physics Research
The long-term goal of the Radiation Physics Research Program in the Department of Radiation Oncology at the University of Pennsylvania is to develop innovative therapeutic solutions for the treatment of human disease. Advancements made towards this goal involves applied physics research in many areas that include high energy proton and photon radiation, use of artificial intelligence (AI) methods, FLASH radiation therapy, photodynamic therapy, dosimetry techniques, and innovative image guided approaches to target radiotherapy for improving patient outcome. Our program is unique in the breadth and depth of the research available and in the wealth of collaborative activities both nationally and internationally as well with industry.
Current support for our research and educational goals include:
- 3 Program Project grants (P01) with our Radiation Biology Division in Translational Studies in FLASH Particle Radiotherapy, Pleura Photodynamic Therapy and Radiation and Checkpoint Blockade for Cancer Immune Therapy.
- Several R01 grant funded research on topics such as: Photodynamic Therapy, Proton Beam Planning, Photo-Acoustics, Ultrasound Hyperthermia, Robotic and Frameless SRS.
- Partnership with Industry supported research: various research grants IBA and VARIAN on new technology and treatment modalities, such as Flash radiotherapy and biologically guided online adapted SBRT.
- Individual faculty research activities many of the funded by the Department of radiation Oncology and by the University.
- National Institute of Health (NIH) and National Cancer Institute (NCI) funded research.
- A large number of collaborative funded research activities with other institutions.
- Global Education and Global Health initiatives funded by the NCI, American Institute of Physics (AIP) and others.
