Los Alamos National Laboratory High Explosives Computational Scientist 4 (Scientist 4) in Los Alamos, New Mexico

What You Will Do_

The Methods and Algorithms Group (XCP-4) of the Computational Physics Division at Los Alamos National Laboratory is seeking outstanding candidates for positions at the Scientist 4 level in the area of continuum solid mechanics modeling. The successful candidates are expected to provide direction and vision, lead in a team environment, look for new opportunities to expand this research area in the group, implement, test and verify their models and algorithms in large production software and publish their research in leading scientific journals.

XCP-4 is a group of about 20 scientists with various technical backgrounds doing cutting edge research in advanced computational methods and algorithms for multi-physics applications in support of national and global security. Specifically, we develop state-of-the art numerical methods for shock hydrodynamics and multiphase flow in both Eulerian and Lagrangian frameworks, as well as advanced physics-based computational models in a variety of areas, including high explosives, turbulent reactive flow, and continuum solid mechanics. Our staff provide expertise in these areas through multidisciplinary interactions on teams seeking to provide solutions for large multi-physics codes. Our work supports a variety of Laboratory missions, including stockpile stewardship, nonproliferation, threat reduction, and energy and environmental sciences.
