Los Alamos National Laboratory Uncertainty Quantification and Machine Learning Postdoc in Los Alamos, New Mexico

What You Will Do_

The Computational Physics: Verification & Analysis group (XCP-8) at the Los Alamos National Laboratory (LANL) has an opening for a postdoctoral research associate in the areas of uncertainty quantification and machine learning. The selected candidate will be part of a multi-disciplinary team as they assess the effect of experimental data on simulation uncertainty in large-scale physics simulations. This will involve collaborating with experimentalists and physics subject-matter experts in order to understand sources and types of uncertainties for a single physics sub-model or experimental setup. An immediate goal of the work will be to develop applications of machine learning classification methods to aid in determining the type of experimental data most needed to reduce simulation uncertainty. Though machine learning has showed promise in many fields, its use in predictive physics-based simulation is still very new. This is a promising growth area that can benefit from new ideas and unorthodox approaches.

Experience with interpreted languages such as Python, Matlab, or R is required, Python experience being the most desirable. The successful applicant should have a strong background in at least one of the specialty areas of continuous optimization, probabilistic optimization, uncertainty quantification, or machine learning methods.

A successful candidate will engage in one or more of the following focus areas:

  1. Developing probabilistic optimization methods related to uncertainty in model parameterization

  2. Development of machine learning algorithms to learn features in a wide variety of data sets that can be informed by experiment

  3. Development of uncertainty quantification methods for reduced order models using machine learning algorithms

  4. Development of methods to propagate uncertainty through large-scale predictive physics-based simulations

What You Need

Minimum Job Requirements:

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

  • Demonstrated ability to communicate research to an interdisciplinary audience and work on an interdisciplinary team

  • Strong programming skills in Python. Alternately experience programming in Matlab or R may be substituted.

  • Familiarity with Unix

  • Demonstrated ability to publish research in peer-reviewed journals or conference proceedings

Desired Skills:

  • Familiarity with TensorFlow and Scikit-learn

  • Familiarity with using High Performance Compute clusters

  • Experience with version-controlled code projects

Education: Ph.D. in mathematics, physics, computer science, statistics, machine learning or a closely related discipline completed within the past five years or to be completed soon prior to employment.

Notes to Applicants: Applicants must submit a CV and include a cover letter describing their research interests. In addition to applying through the official site, please email your CV and cover letter directly to Kyle Hickmann (hickmank@lanl.gov).

Postdoctoral appointments are for two years, with the possibility of a third year extension.

Additional Details:

Q Clearance(Position will be cleared to this level): Applicants selected will be subject to a Federal background investigation and must meet eligibility requirements* for access to classified matter.
