Los Alamos National Laboratory Computational Physics Postdoc in Los Alamos, New Mexico

What You Will Do

Are you ready to begin a career assessing predictive confidence of computational physics codes? If so, we encourage you to learn more about our Postdoctoral Research Associate openings in the Computational Physics: Verification & Analysis group (XCP-8) at the Los Alamos National Laboratory (LANL). We are looking for several highly motivated post-doctoral candidates in at least one of the areas of verification and validation (V&V), uncertainty quantification (UQ), machine learning (ML), and analysis of computational predictions. In this role you will apply analysis methods, including V&V, UQ, Bayesian optimization, deep machine learning, and/or multi-fidelity modeling to assess computational physics simulations of materials under extreme conditions. A background in a relevant field of physics is preferred (e.g. hydrodynamics, fluid dynamics, shock physics, turbulence, solid mechanics, material strength, material failure, plasma physics, radiation transport, and/or magnetohydrodynamics). You will have the opportunity to publish results in peer-reviewed journals and present at top tier conferences.

What You Need

Minimum Job Requirements:

Numerical Methods

You will need experience with many aspects of numerical modeling, including but not limited to experience as a user and/or developer of large multi-physics models, with deep learning and/or with the underlying physics and mathematics of multi-physics models.

Research Expertise

You will need to have conducted high level research in one or more of the following areas: simulation, verification, validation, uncertainty quantification, optimization, inverse problems or a closely related focus area.

Programming

For this role you will need to be familiar with at least one of: Fortran, C++ and/or Python. Alternately experience programming in Matlab and R may be substituted.

Journals/Conferences

You will need to show that you have the ability to publish research in peer-reviewed journals or conference proceedings, communicate research to an interdisciplinary audience and work on an interdisciplinary team.

Education/Experience : PhD in mathematics, physics, materials science, chemistry, engineering, statistics or a closely related discipline. The candidate must be within 5 years of completion of PhD at time of being proposed for review by the committee, or will have completed all PhD requirements by commencement of the appointment.

Desired Qualifications:

  • Experience working with numerical modeling, experimentation, verification, validation and/or uncertainty quantification.

  • Familiarity using High Performance Computing clusters.

  • Experience with radiation transport, high-energy-density physics, equations-of-state, shock physics, high explosive modeling, material failure, material strength under high strain rates, magnetohydrodynamics, and/or materials properties in simulations.

  • Proficient with software engineering tools like: version control systems; web-based software repository systems; issue trackers; online collaboration platforms; and continuous integration systems.

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.

Salary: Competitive salaries are based on the date the PhD degree requirements were completed or the degree was awarded. Starting salary for a new graduate is currently $92,000.

Note to Applicants:

To be considered for the position, applicants should submit a CV/resume and a detailed cover letter addressing how their experience relates to each of the required and desired skills as applicable. Regular post-doctoral appointments are for two years and are renewable for a third year. Outstanding candidates may be eligible for a LANL Director's Fellowship. For specific inquiries regarding the position, please contact Dr. Brandon Wilson ( bwilson@lanl.gov ).

Where You Will Work

XCP-8 is an interdisciplinary group which specializes in VVUQ and analysis of complex numerical codes applying diverse physics models (fluid dynamics, hydrodynamics, solid mechanics, material strength and damage, equation of state, reactive flow, high-energy-density physics, instabilities and turbulence, and radiation transport). Research in XCP-8 is cross-cutting and group members interact closely with code and physics model developers, experimentalists, and simulation end-users across a broad set of physics. XCP-8 offers an exciting, flexible, scientifically challenging work environment with many opportunities to collaborate with the broader LANL scientific community.
