Clinical Interest for Patients
I am a clinical medical physicist, focusing on developing practices that ensure safe, quality patient care. Most recently, I have led the Radiology community in discontinuing the use of patient shielding. This change in clinical practice is based on decades of research, changes in technology, and improved knowledge of the effects of radiation on the human body.
