Rate My Professor Amanda Johnsen

Johnsen's research specializations include isotope production and purification, neutron activation analysis applications, molten salt reactors, reactor production of medical isotopes, non-aqueous reduction processes, dissolution of irradiated fuels, and spectroscopic monitoring of nuclear reprocessing streams. She has received several awards, including the Outstanding Performance Award from Pacific Northwest National Laboratory in 2011, a Graduate Student Fellowship from the National Science Foundation (2003-2006), the Public Policy and Nuclear Threats Fellowship from NSF in 2004, and the Roy Oxford Award from MIT Nuclear Engineering Department in 2000. Key publications include "Optimization and scale-up of a microscale ion exchange separation for an adjacent lanthanide pair" (2026, Separation Science and Technology), "Characterization of the Core Face Irradiation Fixture at the Pennsylvania State Breazeale Reactor" (2024, Nuclear Engineering and Design), "The impact of nuclear data uncertainty on identifying plutonium diversion in liquid-fueled Molten Salt Reactors" (2023, Annals of Nuclear Energy), and "Neutron activation analysis capabilities and applications at the Penn State Radiation Science and Engineering Center" (2018, Forensic Chemistry). Her work contributes to advancements in nuclear engineering, radiochemistry, and safeguards.
