What are the responsibilities and job description for the Design Physics - Postdoctoral Researcher position at Lawrence Livermore National Laboratory?
Company Description
Join us and make YOUR mark on the World!
Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world-changing impact advancing science and technology to strengthen U.S. security and promote global stability.
Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi-domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.
Job Description
We have an opening for a Design Physics - Postdoctoral Researcher. We invite PhD graduates
with expertise in computational and/or experimental physics (with an emphasis on dynamic
behavior of materials) to apply for a Postdoctoral Research Fellowship. The successful
candidate will work with simulation and experimental teams to design, model, conduct, and
analyze data from ring and cylinder experiments on aluminum alloys under extreme loading
conditions. The work will examine how geometry, microstructure, internal defects, and shockgenerated
Damage Influence Metal Fracture And Fragmentation. Additional Responsibilities May
include supporting proposal development, comparing aluminum grades, conducting sensitivity
studies, calibrating material models, and interpreting experimental radiography and
postmortem data. This position will be in the Strategic Deterrence Directorate.
This position may offer a hybrid schedule, which includes the flexibility to work from home one
or more days per week, after a probationary period. The specifics of the hybrid schedule,
including the exact number of days required in the office and virtual work options, may vary
based on the needs of the team and the organization.
