Lorenzo Vergari

BIOGRAPHY
Lorenzo Vergari is a Ph.D. candidate in the SALT group. His research investigates chemistry and engineering of graphite in molten fluoride salt reactors. Lorenzo is a recipient of the Berkeley Graduate Fellowship. Before joining UC Berkeley, he obtained a M.S. in Nuclear Engineering from Politecnico di Milano, a M.S. in Energy and Nuclear Engineering from Politecnico di Torino, and a B.S. in Energy Engineering from Politecnico di Milano.

PROJECTS
Graphite and Tritium Studies in Molten Fluoride Salts
Molten Salt Reactor Test Bed with Neutron Irradiation
Lorenzo’s research projects focus on using graphite as a vector for tritium removal, on preventing salt infiltration in graphite components and on tribology in fluoride systems . Part of Lorenzo’s research is performed in collaboration with MIT, NCSU and ORNL (within the US DOE NEUP) and with Kairos Power.

    • Library Exhibit for the 30th Anniversary of the American Cultures Requirement

      May 24, 2022

      Morrison Library Doe Library

      What could be so important that faculty on campus would agree on creating a new campus-wide requirement? So asked Professor Bill Simmons, first director for the Center for the Study of American Cultures (from 1988-1994). His answer - the teaching and learning of race, racism, and anti-racism in our institutions, communities, local and transnational lives - bringing into life the nation’s first...

      June 3, 2022

      306 (HP Auditorium) Soda Hall

      Classically, most ML methodology has made an innocuous modeling assumption: data drawn from both the training/test sets has been independently sampled from a pair of identical distributions with nice properties. Yet, in the situations modern ML methods must confront, deviations from this idealized setting are quickly becoming the norm–not the exception. We address the challenges arising in...
