Marco T Pigni

Bio

Marco has a Ph.D. in Nuclear Physics with special interest in nuclear reaction theory. He worked on direct and compound nucleus reaction mechanisms and contributed to the development of evaluated nuclear data libraries. He developed methodology to produce covariance information for nuclear reaction models in the low and fast energy regime. Marco received the title of “Dottore Magistrale” at the University of Milan working on emissions of intermediate mass fragments in heavy ion interactions. He also studied at the Atominstitut of the Austrian Universities, Vienna University of Technology where he received his Ph.D. While working at National Nuclear Data Center in Brookhaven National Laboratory as a postdoc research associate and staff member, he contributed to the release of the current U.S. ENDF/B-VII.1 library. Currently at ORNL, Marco focuses on cross section and fission product evaluations along with their covariance information.
