Background

Jack Goodell first joined LLNL as a student from the University of Maryland Department of Chemistry, completing his doctorate work on the use of modeling and simulation tools in developing new isotopic signatures for nuclear forensics applications. He has continued at LLNL as a postdoctoral researcher in the Safeguards, Nonproliferation, and Response Group beginning in 2018, applying both Monte-Carlo simulations and deterministic codes to various nuclear forensics, nonproliferation, and detection capability projects. Since joining LLNL as a postdoc, he has participated in the Public Policy and Nuclear Threats Bootcamp offered though the UC Institute on Global Conflict and Cooperation as well as the International Nuclear Safeguards Policy Course at the Middlebury Institute for International Studies at Monterey Center for Nonproliferation Studies. Current research activities include data analysis for nuclear forensic applications, expansion of radiation detection capabilities through multi-detector gamma-gamma coincidence and X-ray detection systems, and feedstock development of surrogate nuclear fallout materials.

Research Interests

• Post-detonation nuclear forensics
• Improving modeling and simulation of radiation detection systems
