William (Billy) Kennedy, MD, is a radiation oncologist and an assistant professor in the Department of Radiation Oncology at Barrow Neurological Institute.
Dr. Kennedy’s expertise focuses on the treatment of brain and spine tumors using noninvasive
radiosurgery, including Gamma Knife and CyberKnife radiosurgery, stereotactic body radiation
therapy (SBRT), image-guided intensity-modulated therapy (IMRT), and brachytherapy. He is a
member of the American Board of Radiology, the American Society for Radiation Oncology, and
the Society for Neuro-Oncology.
Dr. Kennedy earned his medical degree from the University of Florida College of Medicine in
Gainesville. He completed his residency in radiation oncology at Washington University School
of Medicine and Barnes-Jewish Hospital in St. Louis, where he served as chief resident in his
final year.
Dr. Kennedy’s research interests include developing clinical trials for the management of primary and metastatic central nervous system tumors. He is also focused on novel uses of stereotactic radiosurgery, quality improvement of radiotherapy treatment planning and delivery, and patient-reported quality of life and survivorship. He has authored dozens of peer-reviewed publications on these topics.
