Dr. Brian Kavanagh graduated summa cum laude with honors in biomedical engineering from the Tulane University School of Engineering and then remained at Tulane to receive his MD and MPH degrees from the School of Medicine and School of Public Health. He completed an internship at the Charity Hospital of Louisiana before entering a radiation oncology residency at Duke University, where he was an American Cancer Society Clinical Oncology Fellow. His first academic appointment after his residency was at the Medical College of Virginia, and later he moved to the University of Colorado, where he is now professor and vice-chair of radiation oncology. His current research interests include laboratory studies of how to enhance the effectiveness of radiotherapy by blocking the action of macrophages that stimulate tumor regrowth after treatment, and he also has a special interest in Stereotactic Radiosurgery for Brain Tumors and Stereotactic Body Radiation Therapy for tumors elsewhere in the body. His recent publication list includes numerous peer-reviewed papers and abstracts directly related to SBRT, and he is co-editor of the first textbook of SBRT. He is involved in Health Policy decisions at the national level, serving on a Medicare Advisory Panel and also on the Board of Directors of the American Society of Radiation Oncology (ASTRO).
