Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a Postdoctoral Researcher to conduct research in safety testing and modeling of energetic materials.  You will actively participate in the research to better understand how such materials ignite under various stimuli (e.g., thermal, shock), and work to quantify and understand the reaction violence in accident scenarios. This position is in the Rapid Materials Prototyping and Characterization group of the Materials Science Division.

Essential Duties
- Conduct research in the safety testing and modeling of a variety of energetic materials, ranging from fuel-oxidizer mixtures to cast-cured explosives. 
- Design and build small scale safety testing and/or cook-off tests to better understand how these materials respond under various stimuli, and as a function of a variety of parameters (e.g., particle size, degree of confinement, composition, etc.).
- Use modeling and simulation to understand the reaction violence, for example, the pressurization or transport of thermal energy in the event of an accident.
- Contribute to and actively participate in the conception, design and execution of research to address defined problems.
- Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Collaborate with scientists in a multidisciplinary team environment to accomplish research goal.
- Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.
- Perform other duties as assigned.

Qualifications 
- Recent PhD in materials science, chemistry, engineering or a related field.
- Experience in designing experiments and executing modeling of energetic materials with an emphasis on safety and accident scenarios.
- Knowledgeable of the concepts of reaction kinetics and fluid dynamics under rapid conditions, as is seen in deflagrations and detonations.
- Ability as an innovative experimentalist with a broad range of experience in experimental design, techniques and execution.
- Ability to develop independent research projects through publication of peer-reviewed literature.
- Proficient verbal and written communication skills as reflected in effective presentations 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 computational fluid dynamics, as well as reaction kinetics modeling as applied to energetic materials.
- Knowledge of and/or experience in dynamic characterization of energetic materials during ignition or deflagration / detonation transitions.
- Knowledge of safe handling practice of energetic materials

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:  This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, 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.  Q-level clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note:  This is a two year Postdoctoral appointment 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.
