Researcher

 

Andrea Jokisaari is a Computational Scientist in the Fuel Modeling and Simulation Department of Idaho National Laboratory. Prior to joining INL in January 2018, she completed a two-year postdoc with a joint appointment between Northwestern University and Argonne National Laboratory and received her doctorate from the University of Michigan. Her research interests focus on applying theory and computation to understand the fundamental thermodynamic and kinetic driving forces influencing microstructural evolution at the mesoscale, particularly in extreme environments. She has previously researched hydride nucleation and growth in zirconium for nuclear fuel cladding, microstructure evolution in novel cobalt-based superalloys, and was integral to the development of the phase field benchmark effort led by the National Institute of Standards and Technology. She is currently researching the development of porosity in U-Zr metallic fuels and high burnup structure formation in UO2 fuel with the goal of informing engineering scale fuel performance models.
