Dynamic Properties Materials - Postdoctoral Researcher
Reference #: REF1887F
Job Code: PDS.1 Post-Dr Research Staff 1
Position Type: Post Doctoral
Security Clearance: Anticipated DOE Q clearance (requires U.S. citizenship and a federal background investigation)
Drug Test: Required for external applicant(s) selected for this position (includes testing for use of marijuana)
Medical Exam: Not applicable
We have an opening for a Postdoctoral Researcher interested in the dynamic response of materials at high rates and pressures, including opportunities to study shock produced ejecta, constitutive modeling, and phase transitions. You will work with a team of experienced physicists and engineers to design, execute, and analyze experiments using gas guns, x-ray facilities, and computational/numerical simulations. In this role you will also publish research results in peer-reviewed journals, and present results at external conferences, seminars, and/or technical meetings. This position is in the Materials and Non-Destructive Evaluation Section, within the Materials Engineering Division (MED), in the Engineering Directorate at Lawrence Livermore National Laboratory.
In this role, you will
- Contribute to design, execution, and analysis of studies of material properties under extreme pressure and strain rate conditions. Potential research areas include, but are not limited to, the following topics: shock produced ejecta and jetting, phase transitions, heterogeneous materials, strength, and failure.
- Develop experimental testing plans, including the use of simulation-based design methods.
- Organize, analyze, and present results for an interdisciplinary team.
- Work closely with engineers, scientists, and technicians both at LLNL as well as outside of LLNL, to complete project goals.
- Participate in experiments conducted at off-site facilities.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists.
- Publish research results in peer-reviewed scientific journals and present results at external conferences.
- Perform other duties as assigned.
- Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
- PhD in Mechanical Engineering, Materials Science and Engineering, Physics, or related field.
- Ability to perform independent research and use a scientific approach to solve problems.
- Experience with one or more of the following areas: high-rate experiments, shock compression, mechanics of materials, fluid dynamics, finite element modeling, and hydrodynamic simulations.
- Experience with comprehensive data analysis.
- Experience and innovation in a broad range of computational and experimental design, methods, and analysis.
- Proficient verbal and written communication skills, such as would be needed to write reports, peer-reviewed publications, and proposals.
- Initiative, interpersonal skills, and the ability to work in a collaborative, multidisciplinary team environment.
Qualifications We Desire
- Experience using gas guns, explosives, or lasers to study materials under dynamic pressure; experience working at beamlines/large facilities; or other high-risk, preparation intensive, experimental settings.
- Experience using (multi)physics simulation codes to model experiments, for example, COMSOL, Ansys, Abaqus, CTH, or ideally ALE3D.

COVID-19 Vaccination Mandate
LLNL demonstrates its commitment to public safety by requiring that all new Laboratory employees be immunized against COVID-19 unless granted an accommodation under applicable state or federal law. This requirement will apply to all new hires including those who will be working on site, as well as those who will be teleworking.
LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory. Some positions will require a DOE L or Q clearance (please reference Security Clearance requirement above). If you are selected and a clearance is required, 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. For additional information please see DOE Order 472.2.
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.
Pre-Placement Medical Exam
A job related pre-placement medical examination may be required.
