Rachel’s expertise lies in trace metal analysis by inductively coupled plasma mass spectrometry (ICP-MS). She has 30 years of experience with sample digestion, gravimetric separations and analysis using a variety of ICP-MS platforms (Q-ICP-MS, TQ-ICP-MS and HR-ICP-MS). Prior to joining LLNL as a staff member in 2005, she had analytical chemist and laboratory manager roles at Lawrence Berkely National Laboratory and Washington University.  Since 2007 she has managed the trace element ICP-MS laboratory in NACS.  Her research interests are primarily focused on characterizing uranium materials (ores, uranium ore concentrates, fuel pellets, alloys etc.) for nuclear forensics and safeguard applications.
