Gregory Eiden, Ph.D.

National and Homeland Security

Gregory Eiden is the lead inventor of collision cell inductively coupled plasma (ICP) MS, a method that significantly reduced the impact of spectral interferences in ICPMS and has shepherded the development of specialized MS methods for classified applications which have received significant recognition by the USG. Other research interests include nuclear particle analysis by laser ablation MS, and laboratory methods to create synthetic nuclear explosion debris. He has a bachelor’s degree in chemistry from Harvey Mudd College and a Ph.D. in physical chemistry from the University of Wisconsin-Madison. Following a postdoctoral stint at Los Alamos National Lab, Dr. Eiden joined the staff of the then nascent National Security Directorate at Pacific Northwest National Lab. He joined Idaho National Laboratory in November 2022 in the National & Homeland Security Directorate.
