AI Surrogate Modeling of Continuum Mechanics
- Req. Number: IRC136199
- Organization : XCP-8/Verification And Analysis
- City, State: Los Alamos, New Mexico
What You Will Do
Are you ready to begin a career building AI surrogate models 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 with experience with the computational solid/fluid dynamics, deep learning, and/or analysis of computational predictions. In this role you will apply state of the art generative deep learning methods to build large AI surrogate models of computational physics simulations of materials under extreme conditions. You will be one member of a team that designs, builds, trains, and tests a large AI model. Experience with continuum mechanics (e.g. hydrodynamics, fluid dynamics, shock physics, turbulence, solid mechanics, material strength, material failure) and/or experience with applied mathematics, statistics, and/or deep learning are desired. You will have the opportunity to publish results in peer-reviewed journals and present at top machine learning conferences.
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). AI/ML methods are applied by XCP-8 in a highly interdisciplinary manner 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.

Where You Will Work
Located in beautiful northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security. Our generous benefits package includes:
Additional Details
Directive 206.2: Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States.
Clearance: Q (Position may 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. This position requires a Q clearance which requires US Citizenship except in extremely rare circumstances. Dependent upon position, additional authorization to access nuclear weapons information may be required that may or may not be available to dual citizens depending upon the circumstances.
*Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.
New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer and supports a diverse and inclusive workforce. All employment practices are based on qualification and merit, without regard to race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation or preference, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by federal laws and regulations. The Laboratory is also committed to making our workplace accessible to individuals with disabilities and will provide reasonable accommodations, upon request, for individuals to participate in the application and hiring process.
