About me

Thomas Griglock, Ph.D., is the section chief in radiology and an associate professor in the Department of Diagnostic Radiology. He is also the director of the Oregon Medical Physics Program. He joined OHSU in May of 2012, after completing his M.S. and Ph.D. at the University of Florida, where he also worked as a junior medical physicist at Shands Hospital.

Dr. Griglock specializes in clinical imaging physics and research applications within the field, including CT dosimetry, rational approaches to patient dose monitoring and optimization, and the development of true spectral CT imaging. He is the creator of a novel dose measurement methodology that has resulted in over 30 publications and presentations at national and international conferences and is the subject of ongoing research at the University of Florida. 


Dr. Griglock was awarded the Outstanding Teacher of the Year award by the radiology residents at OHSU in 2014, the OHSU Golden Rose Award for his work in pediatric fluoroscopy in 2013, and the Fitzgerald Award for Outstanding Research by the Florida Chapter of the AAPM in 2012. He is also an Eagle Scout, and spends his free time brewing and enjoying a range of outdoor activities.
