Ryan Stewart
Digital Twin Data Scientist
Idaho National Laboratory
Ryan Stewart is a digital twin data scientist at Idaho National Laboratory in the Digital Engineering
group. His work is in the computational analysis of advanced reactor designs to better understand their
operations, gain insight into safeguarding advanced reactors, and understanding nuclear non-
proliferation consequences. This work has fed into the development of a digital twin to aid in
safeguarding nuclear reactors and the development of a general framework for implementing safety,
security, and safeguards for advance nuclear reactors.
