The Ultrafast Spectroscopy Group in the Department of Nuclear Engineering investigates several topics in plasma science and nuclear engineering. Dr. Bataller’s research group specializes in the application of ultrafast laser techniques for probing matter in extreme environments with a particular focus on molten salts for advanced nuclear energy applications. Molten salt research topics include thermophysical property characterization and their microscopic origins, ultrafast photochemistry of solvated electron, interfacial corrosion dynamics of metals, and plasma engineering for nuclear material accountancy.
