Armstrong is a NSSPI graduate who worked with Dr. Sunil Chirayath to investigate safeguards approaches for Molten Salt Reactors (MSRs) in collaboration with Oak Ridge National Laboratory. This work involves radiation transport modeling and fuel burnup simulations of a thermal neutron spectrum MSR to compute the inventory of Special Nuclear Material production and flow rates in MSRs. She graduated in May 2021 with a Master of Science degree in nuclear engineering, a Certificate in Nuclear Security, and a Certificate in Advanced International Affairs from the Bush School of Government and Public Service. Armstrong was selected to be a NNSA Graduate Fellow in 2021, and began her fellowship upon graduation.
Before joining NSSPI, Armstrong received a Bachelor of Science in Nuclear Engineering with a minor in Radiological Health Engineering from Texas A&M University. Armstrong also interned with the late Senator Daniel Inouye of Hawaii on Capitol Hill and with the United States Secret Service in Washington D.C. where she accompanied Special Agents on Head of State and U.S. President protective missions and also served on the Critical Infrastructure Committee Cyber Security Sector during the 2013 Presidential Inauguration National Special Security Event (NSSE).
