The search for a permanent new chair is ongoing, and an announcement is expected before the end of the year. 

Dr. Dillon is the executive vice Chair of Radiology and Biomedical Imaging and the Elizabeth A. Guillaumin Professor of Radiology. He received his medical degree from the University of California, Los Angeles and completed his residency at the University of Utah, followed by a fellowship in Neuroradiology at UCSF. In 1992, he was appointed Chief of the Neuroradiology section.

He is highly regarded nationally, having served as past president of the American Society of Head and Neck Radiology (ASHNR) and the American Society of Neuroradiology. Dr. Dillon received the Gold Medal from the ASHNR in 2008 and the Gold Medal from the American Society of Neuroradiology in 2015. He was also the recipient of the Outstanding Researcher Award from the American Society of Neuroradiology in 2014.

A consummate teacher as well as a researcher and clinician, he received the Francis A. Sooy, MD teaching award for Clinical Excellence from the Department of Otolaryngology in 1993, and the J. Elliott Royer award for contributions to clinical neurology in 2011. Dr. Dillon has been elected as one of the Best Doctors of America every year since 1995.

“I am deeply grateful for his leadership during this transition. I also want to once again express my profound gratitude to Dr. Ron Arenson for his decades of service and immeasurable contributions to the department and to UCSF,” shared Dean of the School of Medicine Talmadge E. King, Jr., MD in an email to UCSF Imaging. “Please join me in thanking both for their longtime commitment and dedication to our institution, our patients and our learners.”
