The long-term goal of the Radiation Biology Research Program in the Department of Radiation Oncology at the University of Pennsylvania is to improve the outcome of cancer patients through an improved understanding of how ionizing and non-ionizing radiation interacts with biological tissues, as well as the fundamental processes that dictate the pathogenesis, survival and death of cancer cells in the context of the tumor microenvironment. Multiple investigators are brought together in this program to identify the molecular and physiological pathways influencing the response to treatment of tumors and normal tissues. Ongoing efforts are targeted at developing treatments combining radiotherapy with immunotherapy, optimizing precision (personalized) Radiotherapy and Photodynamic Therapy, and applying innovative imaging 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, from molecular studies of how the tumor microenvironment influences tumor response to radio/chemotherapy, to translational projects involving animal models, as well as clinical trials. The research in the Radiation Biology Division is truly "bench-to-bedside".

  • 2  Program Project grants (P01s)  in Photodynamic Therapy and the Unfolded Protein Response & Cancer,
    • 7e
  • a PCORI grant to perform pragmatic trials at the National Level on the use of Protons to treat Breast Cancer 
    • 18
  • 7 R01 grants
    • 1e
  • 3 DoD grants 
    • f1
  • NIH R25 Summer Undergraduate training grant to train new generation of scientists in Radiation and Imaging Sciences (SUPERS) is currently in its 15th year of funding.
    • 84
  • Multiple investigators in the Division and the Department are further supported by industry and foundation grants. 
    • 7

In all, the aggregate annual budget for research support totals over 7 million dollars. The Division has a dedicated administrative staff that manages these grants, as well as several lecture series that feature collaborators and renowned scientists from across the globe. In recent years the Division has ranked number 1 or 2 in National Institutes of Health grant funding among comparable programs in the country.

Our preclinical research efforts are enhanced with an advanced Cell and Animal Radiation Core facility (CARC) and a dedicated Proton animal treatment room. The opening of our Proton/Photon Research Room in 2017 brought research opportunities to the top level. The platform was designed to precisely deliver photon radiation to the model, but since it is mounted on a rail system, the model can also be positioned directly in front of the research proton beam.

There is much excitement surrounding FLASH Radiotherapy, emerging technology where an entire treatment of radiation therapy will be given in one highly concentrated dose to the patient lasting only seconds. Many scientists throughout UPenn's departments are collaborating together to study the relationship between FLASH radiation and immunotherapy treatments where the side effects of traditional radiation therapy will be lessened dramatically. Though still in preclinical studies, research is progressing.
