Ken Lewis, PhD, is a board certified (DABR) Diagnostic & Nuclear Medical Physicist, a board certified (CHP) Health Physicist, and an Assistant Professor in the Department of Radiology and Radiological Sciences. As a Medical Physicist, his focus is on clinical image quality, patient dosimetry, imaging protocol development, and radiation safety. As an educator, he participates in teaching courses for both the VUSM Doctorate of Medical Physics program and the Radiology Residency training program.

Dr. Lewis earned his Masters in Medical Physics (2006) and PhD in Physics (2013) from Vanderbilt University. His past research interests were in x-ray phase contrast and small-angle x-ray scattering imaging. Post graduation, he served as a Medical Physicist and Radiation Safety Officer for Ochsner Health System in New Orleans, LA (2013-2016) before returning to VUMC.

Prior to entering the Medical Physics field, Dr. Lewis served on active-duty as a U.S. Navy Submarine Officer. He was recalled to active-duty to serve in Iraq (2010-2011); he retired from the U.S. Navy Reserve in 2017.
