**What You Will Do** The Space Nuclear Sensing Group (ISR-8) is seeking a Postdoctoral Researcher to contribute to national security programs involving on radiation detection and nuclear sensing. ISR-8 develops radiation sensing technologies and physics-based interpretation for x-ray, gamma-ray, and neutron detection in support of national security and space science missions. The group performs detector development, radiation transport modeling, and end-to-end mission systems analysis in close collaboration with engineering partners. The successful candidate will conduct research in radiation detection with emphasis on radiation data analysis and radiation transport modeling. Responsibilities include analyzing experimental radiation measurements, developing radiation transport simulations, and comparing detector data with simulated detector response. Candidates with experience in radiation detector physics, radiation transport simulations, or experimental radiation measurements are especially encouraged to apply. Research areas may include: - Modeling radiation detector response to x-ray, gamma-ray, and neutron sources in space - Development of analysis methods for identifying and characterizing radiation sources using detector measurements - Simulation and validation of detector performance using radiation transport codes (e.g., Geant4, MCNP) - Cross-comparison of simulated and experimental radiation measurements to improve detection algorithms and system performance Opportunities may exist to compare simulation results with experimental detector measurements and to collaborate with teams performing detector characterization. This position provides the opportunity to work on challenging radiation sensing problems supporting national security and space missions alongside a multidisciplinary team of scientists and engineers across ISR and other LANL divisions. **What You Need** **Minimum Job Requirements** - Demonstrated ability to work collaboratively in multidiscip
