Meet The Faculty

The Department of Radiation Oncology at Mayo Clinic's campus in Jacksonville, Florida, is part of the nationwide Mayo Clinic organization. Patients in Jacksonville receive the benefits of all Mayo Clinic programs that study and treat malignant diseases.

From the program directors

On behalf of Mayo Clinic faculty in Jacksonville, Florida, welcome to the Radiation Oncology Residency website! We're thrilled that you're considering our program. We hope that you will find this website helpful in highlighting what our program has to offer and that it can answer all of your questions.

Educating the next generation of physicians has been an integral part of Mayo Clinic since its founding.

Faculty

The faculty involved in the Radiation Oncology Residency program includes 12 radiation oncologists, 10 radiation oncology physics consultants, and two cancer biologists.

Our radiation oncologists have a wealth of experience in every aspect of radiation oncology. Their expertise includes all areas of clinical practice and basic and applied research, education, and professional activity. This is demonstrated through leadership in national organizations, the certification and peer-review process, and educational involvement.

Our radiation oncology physics consultants work directly with staff physicians and residents and direct the teaching of radiation physics. These individuals demonstrate expertise through involvement in leadership in national organizations, the certification and peer-review process, as well as educational involvement.

Our cancer biologists have dedicated laboratory space on site and are available to residents for scholarly research. They are co-directors of the radiobiology course, give multiple lectures within the course, and meet with residents to answer questions. 

Each faculty member works with residents and is available for clinical and research mentorship.
