Two New AEDs Beginning Their Work in July


Starting July 1, the ABR will have two new associate executive directors (AEDs). Geoffrey Ibbott, PhD, will be replacing Donald Frey, PhD, for medical physics, and James Spies, MD, will take over for Anne Roberts, MD, for interventional radiology.


Both will act as liaisons to the board and other stakeholders. The ABR employs four AEDs as part-time staff, including those for diagnostic radiology and radiation oncology.


Dr. Ibbott is professor emeritus and former chair of the department of radiation physics at the University of Texas MD Anderson Cancer Center in Houston. He earned a bachelor’s degree in physics from the University of Colorado, a master’s in medical physics from the University of Colorado Health Sciences Center, and a PhD in radiation biology from Colorado State University. He was an ABR trustee and governor from 2007 to 2017, including time as secretary-treasurer.


Dr. Spies is chief of service and chairman of the department of radiology at Georgetown University Hospital. He graduated from Georgetown University School of Medicine in 1980. Dr. Spies completed a radiology residency at the University of California, San Francisco and a fellowship at New York University in vascular and interventional radiology. He has been an ABR trustee since 2016.


Please join us in welcoming Drs. Ibbott and Spies and thanking Drs. Frey and Roberts for their work.
