Dr. Stea earned his doctorate in biochemistry at UCLA, followed by a medical degree from George Washington University, Washington, D.C. He received his residency training in radiation oncology at the National Cancer Institute in Bethesda, MD. Since his appointment with The University of Arizona Cancer Center, Dr. Stea has served as Director of the Radiation Oncology Residency Training Program from 1995-1998, and has been Medical Director of the Department since 1997. Dr. Stea has been head professor of the Department of Radiation Oncology since 2003.

Dr. Stea is board-certified in radiation oncology, and specializes in the treatment of malignant and benign brain tumors using stereotactic radiosurgery (SRS). He developed the stereotactic radiosurgery program at the University of Arizona, and has more than 20 years of experience in the field.

Dr. Stea's research is focused on the development of novel radiation enhancers and radiosensitizing drugs for primary and secondary brain tumors. His clinical practice focuses on treatment of malignant brain tumors and pediatric cancers, including total body irradiation (TBI). He received the UMC “Patient's Choice Award" for outstanding communication and excellence in patient care 1994, 1995 and 1998, and has been listed among The Best Doctors in America since 1996.
