Postdoctoral Research Associate in Radiation-Resilient Scintillator Materials for Fusion Diagnostics

** What You Will Do*
* The Materials Science and Technology Structure / Property Relations group (MST-8) at Los Alamos National Laboratory seeks a highly motivated Postdoctoral Research Associate to develop next-generation radiation-resilient scintillator materials for fusion energy and national security applications. The successful candidate will work at the interface of experimental materials science and computational modeling to understand how radiation-induced defects form, evolve, and degrade scintillator performance under extreme environments.

The project combines controlled ion irradiation experiments, advanced structural and spectroscopic characterization, atomistic electronic structure calculations, and multiscale defect evolution modeling to establish predictive structure-property relationships for scintillator degradation. The ultimate goal is to enable the design of radiation-hardened scintilla tors with improved lifetime and performance for fusion diagnostics and other radiation detection technologies.

The postdoctoral researcher will work closely with experimentalists and computational scientists across Los Alamos National Laboratory and will have opportunities to contribute to high-impact publications, present research at international conferences, and participate in multidisciplinary collaborations supporting DOE Office of Science and NNSA mission areas.
