Biography

Dr. Benjamin Parruzot is a scientist at Pacific Northwest National Laboratory (Richland, WA, USA) in the Radiological Materials Group. His work focuses primarily on the study of the long-term alteration of low-activity as well as high-level nuclear waste glasses. 

Benjamin holds a PhD from the University of Montpellier (France) for work focused on the use of basaltic glasses as natural analogues to the long-term behavior of nuclear waste glasses in repository conditions, performed at CEA Marcoule (France) under the direction of Stéphane Gin and Patrick Jollivet. He also holds an MS in Chemistry and Chemical Engineering from the Royal Institute of Technology (Stockholm, Sweden).
