Postdoctoral Research Associate in in-situ​/operando X-ray Absorption Spectroscopy

** What You Will Do*
* The Materials Science and Technology Structure/Property Relations (MST-8) group at Los Alamos National Laboratory seeks a highly motivated Postdoctoral Research Associate to develop and apply advanced in situ and operando X-ray spectroscopy techniques to understand the chemistry and local structure of critical materials during chemical separation and electrochemical processes. The successful candidate will use synchrotron-based X-ray absorption spectroscopy (XAS), including (HERFD) XANES and EXAFS, together with complementary characterization techniques to investigate coordination chemistry, chemical speciation, and reaction mechanisms under relevant processing conditions.

Research opportunities include rare-earth and other critical-material systems, with an emphasis on understanding how local chemical environments and interfacial processes influence separation and electrochemical behavior.

The postdoctoral researcher will design and conduct experiments at DOE Office of Science synchrotron user facilities, develop in situ and operando sample environments, analyze and interpret spectroscopic datasets, and collaborate with interdisciplinary teams at Los Alamos National Laboratory and partner institutions. This position offers opportunities to lead beamtime campaigns, publish high-impact research, and contribute to the development of next-generation characterization capabilities for critical-materials research.
