Isabella Van Rooyen
Pacific Northwest National Laboratory
Dr. Isabella J. van Rooyen joined Pacific Northwest National Laboratory (PNNL) in December 2021 as an advisor for Advanced Material Systems where she is developing and implementing new nuclear materials development and advanced manufacturing strategies. She is the United States representative on the International Advanced Manufacturing and Materials Engineering Taskforce for the generation IV international forum (GIF) and the Material Development technical area lead for the Advanced Materials and Manufacturing Technologies (AMMT) program for the Department of Energy (DOE) Nuclear Energy Enabling Technologies. Prior to joining PNNL, Dr. van Rooyen supported DOE’s vision and needs in advanced materials and manufacturing planning and execution as the national technical director for the Advanced Methods for Manufacturing program of the DOE Nuclear Engineering Office.
Dr. van Rooyen’s cross-cutting research spans advanced manufacturing processes, advanced material development, and advanced characterization techniques. Her leadership roles have furthered advanced manufacturing techniques in laser materials processing, casting processes, powder metallurgy, and additive manufacturing processes. She initiated and led projects on the development of metal, ceramic, and matrix materials for high-temperature applications as well as various materials for nuclear fuels. In addition, she pioneered, optimized, and championed novel characterization and electron microscopic techniques to enable and improve fission product mechanistic studies and product performance and qualification at all scales and across material life spans. She holds a PhD in physics from Nelson Mandela University, a master’s degree in metallurgy from the University of Pretoria, and an MBA from Northwest University.
