Atomistic Simulations Jobs (NOW HIRING)

Description
Job Title Postdoctoral Research Associate in Materials Modeling of Plasticity and Microstructure Evolution
Location Los Alamos, NM, US
Organization Name MST-8/Structure/Property Relations
Minimum Salary
Maximum Salary
What You Will Do
The MST-8 Materials Science and Technology group at Los Alamos National Laboratory has exceptional opportunities for postdoc candidates in the field of materials modeling, particularly atomistic and mesoscale modeling of plasticity, deformation twinning, recrystallization, and damage in heterogeneous crystalline metals.
The selected candidate will join the MATEE (Materials Modeling And characTerization under Extreme Environments) team within MST-8. The MATEE team focuses on the development and use of advanced computational mechanics models to predict the effects of extreme and complex environments on both mechanical response and microstructure evolution in materials. Environments considered include high stresses, temperatures, radiation, and corrosion. The MATEE team adopts both hierarchical and integrated multiscale modeling and characterization strategies for mechanical deformation problems.
You should have a strong publication record, an interdisciplinary research philosophy, and the ability to effectively communicate with researchers with varied backgrounds. As a postdoctoral research associate, you will be given the opportunity to publish results in high-impact peer-reviewed journals and present at well-known conferences. The position is for two years, with a third year possible based on performance and funding.
The successful candidate will lead the development and application of multiscale computational models for hexagonal close-packed materials, with emphasis on atomistic modeling, deformation twinning, twin-grain-boundary interactions, microstructure evolution, and recrystallization. The work will focus on linking atomistic and lower-scale mechanisms to mesoscale and continuum descriptions of plastic deformation and microstructure evolution, including the effects of grain boundaries, twin networks, prior microstructure, and texture. The candidate will contribute to atomistic, phase-field, and related modeling approaches to predict deformation twinning, recrystallization, grain-size evolution, and texture-sensitive material response under representative thermomechanical conditions, using reproducible high-performance computing workflows and uncertainty-aware model development.
What You Need
Minimum Job Requirements:

• Strong knowledge of deformation mechanisms in metals, including dislocation plasticity, deformation twinning, and grain-boundary-mediated deformation.
• Experience with computational modeling of plasticity, microstructure evolution, or mechanical behavior in crystalline materials.
• Demonstrated knowledge of metals deformation behavior, microstructure evolution, and microstructure-property relationships.
• Evidence of peer-reviewed publications in relevant journals.

Desired Qualifications:

• Experience in atomistic simulations
• Experience in finite element-based simulations
• Experience in phase field modeling
• Experience in Fast Fourier Transform (FFT)-based simulations
• Experience with hexagonal close-packed metals, zirconium alloys, titanium alloys, magnesium alloys, or related structural materials.
• Ability to effectively program in C++, Python, or Fortran
• Ability to adapt to new project requirements and learn new tools as needed

Education: A PhD in nuclear engineering, materials science, physics, or a related engineering discipline completed within the last 5 years or soon to be completed.
Work Location : The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
