Massimiliano Fratoni is Xenel Distinguished Associate Professor in the Department of Nuclear Engineering at the University of California, Berkeley (UCB).
He received a Laurea in Nuclear Engineering from Sapienza Università di Roma (Italy), and a MSc and a PhD from the University of California, Berkeley.
Prior to joining the Nuclear Engineering Department at UCB, he held a Research Scientist position at the Lawrence Livermore National Laboratory and a faculty position at The Pennsylvania State University.
Professor Fratoni’s research focuses on solving the engineering challenges associated with developing and deploying advanced reactors and advanced fuel cycles. Throughout his career, he has developed a comprehensive understanding of advanced reactors by contributing to the design and development of virtually all Generation IV concepts and beyond. His expertise spans solid- and liquid-fueled molten salt reactors, as well as sodium- and lead-cooled fast reactors. His broader contributions include reactors for space applications, accident-tolerant fuels, fusion reactors, waste repository performance, machine learning applications for nuclear data and reactor operation.
