PNNL

Eirik Krogstad is a senior scientist in the Environmental Signatures Team of the National Security Directorate at Pacific Northwest National Laboratory (PNNL). He joined PNNL in 2011, after spending 21 years in university faculty positions. The work performed by Krogstad, his students, and his mentored staff has always involved the use and development of mass spectrometric methods, applying the measurement of precise trace element and isotopic signatures to answer significant questions. Initially, his research focused on understanding details of early Earth evolution, and later work was directed toward understanding the movement of elements in modern environments. More recently, his work has shifted to the measurement of trace isotopic signatures of nuclear processes. This most recent role has resulted in him leading the mass spectrometric characterization of environmental samples for the International Atomic Energy Agency’s Network of Analytical Laboratories.
