Dr. Morrison joined our radiation oncology faculty after completing his radiation oncology residency in our very own department. Prior to his residency, he completed his internship year at Tucson Medical Center's THMEP transitional year program. He is a graduate of the University of Arizona's College of Medicine and a member of the Alpha Omega Alpha (AOA) Medical Honor Society. He completed his undergraduate education in biomedical engineering and mathematics at Tulane University in New Orleans, LA and a Ph.D. in microbiology and pathobiology at the University of Arizona prior to attending medical school. He also has worked as a research scientist in molecular diagnostics for Ventana Medical Systems here in Tucson, a software engineer for a large international media corporation in New York and Los Angeles, and as a freelance photographer with work published by Sports Illustrated, ESPN The Magazine, and numerous newspapers around the country, like the USA Today and Los Angeles Times.

He is married to a near-native Tucsonan and they have two energetic and inquisitive children who keep them busy at home. Outside of work, he enjoys traveling to new places, playing tennis and golf, skiing, and reading.
