Job Description

We have multiple openings for Postdoctoral Researchers with outstanding research track-records in physical sciences with interest in career growth in optimization, machine learning, automatic differentiation, and computational inverse problems. Knowledge in any of the following areas would also be valuable: high-pressure and high strain rate physics, the physics of energetic materials, atomistic materials modeling, transport properties of materials, multi-scale modeling, or hydrodynamic simulations.

 The positions are envisioned to combine physics and optimization experience to promote scientific and programmatic growth within the strengths of the group. Specific investigations include combining complex hydrodynamics models with computational approaches to facilitate large-scale investigations and machine learning-based design optimization. Specifically, the candidates will actively participate in exciting research within the group that includes Richtmyer-Meshkov and other instabilities; model development describing fundamental, dynamic processes; and multi-scale and continuum computational investigations of the effect of such processes on bulk material behavior.  Uniquely, the group also has strongly coupled experimental and theoretical efforts in these mentioned areas.  These positions are in the Material Dynamics and Kinetics group in the Materials Science Division.

You will 

  • Develop world-leading ML and optimization techniques to study problems in physics.
  • Conduct research to understand the fundamental phenomena that affect or control dynamic materials properties, including material instabilities, plasticity/strength, porosity, and phase transformations kinetics.
  • Contribute to the conception, design, and execution of research to address defined problems.
  • Engage in scientific and programmatic connections with Laboratory-wide efforts and customers, through the promotion of research advancements that tackle Laboratory missions.  
  • Develop understanding of customer needs in order to contribute to development and sustenance of funding support for new and existing research both within and outside of LLNL.
  • Maintain and establish laboratory protocols.
  • Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.
  • Perform other duties as assigned.


  • This position requires either no security clearance, or a Department of Energy (DOE) L-level or Q-level clearance depending on the particular assignment.
  • PhD in Chemistry, Materials Science, Engineering, Mathematics, Physics or a related field.
  • Experience in one or more of the following areas areas: Computational multiscale modeling, energetic materials, molecular dynamics, multi-physics, hydrodynamics, non-equilibrium statistical physics, highly dynamic high-pressure physics, optimization, machine learning, or computational inverse problems.
  • Proven track record as an innovative computational scientist with experience in dynamic materials phenomena or optimization techniques.
  • Ability to represent and document research through programmatic and scientific presentations and publications or technical reports of results.
  • Proficient verbal and written communication skills as reflected in effective presentations at seminars, meetings and/or teaching lectures.
    Initiative and interpersonal skills with desire and ability to work in a collaborative,

Qualifications We Desire

  • Experience working with or implementing world-class computational physics and hydrodynamic codes.
  • Knowledge in fluid dynamics and condensed matter physics.
  • An established record of conceiving and executing pioneering multidisciplinary projects.
