Telephone: 919-681-8006


David graduated from North Carolina State University in 2013 with a B.S. in Biomedical Engineering. His interests led him to the Medical Physics Graduate Program at Duke University where his thesis research involved image processing of breast CT data for the purpose of creating virtual phantoms. David graduated from Duke in 2015 with his M.S. in Medical Physics and commissioned as an officer in the United States Air Force. He was stationed in Northern California for two years where he worked as a clinical medical physicist and medical radiation safety officer. He is grateful to be back at Duke for clinical residency training with CIPG.

Francesco Ria, DMP

Research Scholar


Email: francesco.ria@duke.edu
Telephone: 919-668-6197
Website: Research Gate


Francesco has a Doctor of Medical Physics, Master in Astroparticle physics, and Professional Doctorate in Marketing and Management, and he is a professional journalist. Currently, his research focuses on image quality reference levels definition in CT, phantom image quality prediction, and radiation risk metrics evaluation and definition. In the past, he has also worked in radiation therapy (Cyberknife©) and in radiopharmaceuticals (cyclotron manager). Through life experiences, he has learned that, sometimes, a problem's solution is not in a book, but instead in a night with wine and blues. If you play soccer, be warned: he could be your next referee, and his southern Italian blood does not react well to argument, unless it is over sharing a beer.
