About this position

Idaho National Laboratory is seeking a Computational Materials Modeling Postdoctoral Researcher for its National Security Solutions organization in Idaho Falls, Idaho. The researcher will join an interdisciplinary research and development team developing a hybrid experimental and computational framework for evaluating material performance in engineered systems.

The project will connect material behavior across scales, from microstructure measurements to performance predictions for full-scale systems. The researcher will implement traditional high-fidelity models, develop simplified surrogate models, and quantify uncertainty in computational analyses. The work involves collaboration with teams that provide experimental data, conduct testing, and develop physics-based machine-learning models.

Potential research areas include microstructure reconstruction from EBSD and related datasets, surrogate microstructure generation, crystal plasticity using reconstructed or surrogate meshes, physics-based fatigue and crack-growth modeling, microstructure-dependent fatigue-life prediction, and dynamic material response. The role may also involve designing and analyzing experiments such as laser-shock, parallel-plate-impact, or Kolsky Bar testing.

Computational activities may include continuum-scale explicit dynamic modeling, mesh generation, and simulations using tools such as LS-DYNA, Abaqus Explicit, Ansys Explicit, Peridigm, CTH, ALEGRA, ALE3D, EPIC, Sierra, or comparable software. Work in Linux and high-performance computing environments, including job scheduling with SLURM or PBS, is also relevant.

The postdoctoral researcher will contribute independently and collaboratively, prepare technical reports and scientific manuscripts, and potentially present research at national conferences and meetings. Because the work supports national security applications, some publications and presentations may have limited distribution.

The research environment is based at Idaho National Laboratory, a U.S. Department of Energy national laboratory focused on nuclear energy, clean energy, and critical infrastructure security.

Funding details

The position offers an annual salary of $105,144. Benefits include medical, dental, vision, flexible spending accounts, postdoctoral 401(k) self-contribution access, paid personal leave, eligible-position tuition assistance, and a comprehensive relocation package. Benefit eligibility depends on employment status and position classification.

What's required

Applicants must have a PhD in Physics, Mechanical Engineering, Aerospace Engineering, Materials Science, Applied Mathematics, or a comparable discipline, completed by the start of the appointment and within the previous five years. Candidates must be able to obtain a DOE L clearance, which requires U.S. citizenship, and demonstrate oral and published written communication skills in English. Familiarity with data-analysis languages and tools such as C++, Python, MATLAB, R, or Octave is required, along with willingness to learn by doing. Preferred experience includes surrogate-model development, uncertainty quantification, microstructure reconstruction, crystal plasticity, fatigue and crack-growth modeling, dynamic material response, experimental design, continuum-scale explicit dynamics, mesh generation, Linux/HPC environments, and SLURM, PBS, or similar scheduling systems.
