Bio
Dr. Sabau seeks to advance manufacturing and energy systems for harsh service conditions (extreme environments). His research is focused on advancing materials development/manufacturing for process electrification and industrial decarbonization through the development of multiphysics simulation models for processing-microstructure-property optimization. He developed multiphysics simulation models and source-codes (fluid dynamics, energy transport, phase change, and solid mechanics) for new design explorations and evaluation of component performance in extreme environments and harsh service conditions (utility power plants, nuclear fusion). His expertise includes process modeling and experimental design of additive manufacturing, metalcasting, heat exchangers, and cooling/structural integrity of high-heat flux components, leading multidisciplinary teams.
