Born 1948, graduated in physics in 1971 from the Sapienza University of Rome. 1972–76 fellow and researcher in the Faculty of Medicine of Sapienza. 1976–86 assistant professor and then associate professor in the Faculty of Medicine of the University of L'Aquila in 1983. 1986–2008 in the Faculty of Science—Department of Physics of Sapienza. 2008 full professor of Applied Physics at the Department of Basic and Applied Sciences of Sapienza University of Rome. His research interests have been focused on the development of ND techniques, applied nuclear physics, imaging and image processing, archaeometry and conservation. He is the author of a large number of papers concerning x-ray physics and the development of techniques in journals of physics and applied physics and, more recently, on techniques for image acquisition and processing. He is involved in international collaboration and has been invited to speak at national and international conferences in biomedical physics and archaeometry.
