Our Faculty

Our Department of Radiation Oncology includes 18 attending faculty members who are national and international leaders in their respective subspecialties. Our faculty directly contribute to current guidelines and standards of care in radiation oncology, and are active participants in and collaborators with the Radiation Therapy Oncology Group, the National Comprehensive Cancer Network, and the National Cancer Institute of the National Institutes of Health.

Within the department, our faculty offer residents direction, leadership, and support during daily clinical duties as well as in research planning and investigation. They also routinely teach as part of didactic sessions, grand rounds, tumor boards, and clinical conferences.
