Mesoscale Modeling - Postdoctoral Researcher -

Lawrence Livermore National Laboratory
Livermore, CA 94550

Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

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 inone 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).

Essential Duties
- 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.

- Recent 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 effectivepresentations at seminars, meetings and/or teaching lectures.
- Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.
Desired Qualifications
- 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.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance: None required.

However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process. This process includes completing an online background investigation form and receiving approval of the background check. (This process does not apply to foreign nationals.)

Note: This is a two year Postdoctoral appointment with the possibility of extension to a maximum of three years. Eligible candidates are those who have been awarded a PhD at time of hire date.
