Job Description
Join us and make YOUR mark on the World! 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.
Requirements
- Develop and validate a multiscale simulation framework for radiation-induced defect evolution in complex alloys, focusing on refractory high entropy alloys (RHEAs).
- Implement the framework in parallel simulation codes intended to run on LLNL supercomputers.
- Integrate FP-KMC, on-lattice KMC, and MD methods to achieve atomic-resolution modeling over extended timescales.
- Parameterize defect migration energies from atomistic simulations and incorporate results into KMC simulations.
- Perform MD simulations to predict primary damage cascades and point defect production rates.
- Analyze simulation outputs to predict macroscopic swelling and strain hardening.
- Interface with experimentalists and AI practitioners to validate models and propose directions for alloys property optimization.
- Work both independently and collaborate with others in a multidisciplinary team environment to accomplish program goals.
- Publish research results in peer-reviewed scientific journals and present results at external conferences, seminars, and/or technical meetings.
- Perform other duties as assigned.
