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.
