What You Will Do

The Computational Physics: Verification & Analysis group (XCP-8) at the Los Alamos National Laboratory (LANL) is seeking several highly motivated post-doctoral candidates in the areas of verification, validation, uncertainty quantification (VVUQ) and machine learning. A successful candidate will develop advanced estimation, validation and uncertainty quantification methodology using advanced statistical methods, including Bayesian optimization, machine learning, and/or multi-fidelity modeling. A background in a relevant field of physics is preferred (e.g. fluid dynamics, hydrodynamics, solid mechanics, materials, equation of state, reactive flow, high explosives, high-energy-density physics, instabilities and turbulence, and radiation transport). Successful applicants will be expected to publish results in peer-reviewed journals and present at well-known conferences. This work is part of a larger project. Successful applicants will be expected to work well in a team environment.

XCP-8 is an interdisciplinary group which specializes in VVUQ of complex numerical codes coupled by 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 interacts 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.

What You Need

Minimum Job Requirements:

  • Demonstrated experience with numerical modeling, development of physics models, and/or understanding of relevant physics and mathematics.

  • Research-level expertise in simulation, validation, uncertainty quantification, optimization, machine learning, or a closely related focus area.

  • Strong programming skills in at least one of: Fortran, C++ and/or Python. Alternately experience programming in Matlab or R may be substituted.

  • Demonstrated ability to publish research in peer-reviewed journals or conference proceedings, communicate research to an interdisciplinary audience and work on an interdisciplinary team

  • Excellent written and communication skills in English.

Education/Experience : PhD in mathematics, physics, computer science, engineering, statistics, machine learning 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 both numerical modeling and experimentation.

  • Experience designing, training, and analyzing deep neural networks, or other machine learning techniques such as Gaussian processes.

  • Familiarity using High Performance Computing clusters

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

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

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. Kyle Hickmann ( hickmank@lanl.gov ).
