Kinetic Modeling of Materials Degradation - 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 2019 Best Places to Work by Glassdoor!

We have multiple openings for Postdoctoral Researchers in the area of multiscale modeling of oxidation, hydriding, and electrochemical corrosion in metals with two possible primary research thrusts: (1) atomistic modeling of hydriding and oxidation reactions, (2) reactive phase-field modeling of microstructural evolution. The atomistic aspects of the project will leverage semi-empirical quantum calculation methods to develop a general-use kinetic Monte Carlo code for clustering and nucleation kinetics. The phase-field part of the project will incorporate reactions, mass transport, and nucleation to determine rates of product phase formation and growth. The technical goals of this work will involve tight integration with state-of-the-art experimentation to establish the chemical and physical properties of chemical degradation processes. This position is in the Materials Science Division.

Essential Duties
- Contribute to quantum calculations and code development for massively parallelized software suite for kinetic Monte Carlo simulations of bulk and surface chemistry and/or contribute to development and use of reactive phase-field models related to mesoscale corrosion processes.
- Collaborate with computational and experimental scientists in a multidisciplinary team environment to accomplish research goals.
- Contribute to the conception, design, and execution of research to related to the study of materials under extreme thermodynamic conditions.
-Publish in peer-reviewed journals and communicate research findings at national and international conferences and meetings.
- Pursue independent but complementary research interests and interact with a broad spectrum of researchers within and outside the Laboratory.
- Perform other duties as assigned.

- Recent Ph.D. in Materials Science, Physics, Chemistry, Engineering or related field.
- Experience in first-principles simulation techniques of condensed phases, and/or experience in phase-field modeling or comparable continuum modeling techniques for reactive materials.
- Experience in programming in C++, FORTRAN, Python, or an equivalent high-level language.
- Ability to develop independent research projects through publication of peer-reviewed literature.
- 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.
- Recent record of peer-reviewed publications.
Desired Qualifications:
- Experience in simulations of oxidation, hydriding, or corrosion processes in metallic alloys, or performing large-scale simulations on high-performance computing environments.
- Experience in modeling of phase transformations involving microelasticity or plasticity effects.
- Experience with the application of machine learning methods to accelerate materials research.

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.

Note: This are two year Postdoctoral appointments with the possibility of extension to a maximum of three years. Eligible candidates are recent PhDs within five years of the month of the degree award at time of hire date.
