Company Description

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is essential to innovation and creativity for continued success of the Laboratory’s mission.

Job Description

We have multiple positions for Postdoctoral Researchers to conduct research in the area of mesoscopic modeling of materials microstructures and reactive interface kinetics for metal-hydrogen systems. You will actively participate in the research and development of mesoscale computational models and codes for investigating mechanisms and simulating coupled kinetic processes in materials in  one or both of the following focus areas: (1) metal hydrides for hydrogen-based energy storage; and (2) materials degradation mechanisms driven by metal hydriding. These positions are in the Computational Materials Science group of the Materials Science Division and are associated with the new Laboratory for Energy Applications for the Future (LEAF).

In this role you will

  • Conduct fundamental and applied research in the kinetics of hydrogen interactions with materials.  
  • Develop integrated modeling and simulation capabilities for simulating concurrent chemical and materials kinetic processes in energy storage and/or structural materials. 
  • Design and perform systematic computer simulations on LLNL supercomputers for establishing the foundational understanding of operating kinetic mechanisms in these materials.
  • Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
  • Collaborate with scientists in multidisciplinary team environment within the DOE Energy Materials Network, including experimental and multiscale modeling experts.
  • Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.
  • Perform other duties as assigned.


  • PhD in materials science, chemical engineering, mechanical engineering, physics, applied mathematics, or related field.
  • Broad based knowledge in materials phase transitions and/or chemical kinetic mechanisms.
  • Experience with the phase-field method or comparable continuum modeling techniques.
  • Experience with numerical methods for solving partial differential equations such as finite difference, finite element, and/or spectral methods.
  • Experience writing computer codes and/or advanced numerical solvers.
  • Ability to develop independent research projects demonstrated through publication of peer-reviewed journal articles.
  • 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, multidisciplinary team environment.

Qualifications We Desire

  • Experience with FORTRAN, C/C++, and parallel computing.
  • Experience in theoretical/computational studies of material microstructure evolution involving microelasticity effects, interfacial chemical reactions, and/or metal-hydrogen interactions.
  • Experience with developing quantitative, parameterized phase-field models for solid-state phase transformation of real materials systems.

Security Clearance

LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory.  Most positions will require a DOE L or Q clearance (please reference Security Clearance requirement).  If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  An L or Q clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.  For additional information please see DOE Order 472.2.
