Resonance Ionization Mass Spectrometry - 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 2020 Best Places to Work by Glassdoor!

We have an opening for a Postdoctoral Researcher. You will perform Resonance Ionization Mass Spectrometry (RIMS) and Secondary Ion Mass Spectrometry (SIMS) of cosmochemistry, environmental, and anthropogenic samples for chemical and isotope abundance measurements to support LLNL programs in nuclear forensics and cosmochemistry. You will actively participate in innovative research utilizing state of the art measurement techniques as well as further develop and maintain these techniques. This position is in the Chemical and Isotopic Signatures group of the Nuclear and Chemical Sciences Division.

Essential Duties
- Independently prepare, analyze, interpret and present results from complex environmental and anthropogenic samples for chemical and isotope abundance measurements including but not limited to U, Th, Pu, and REE using state-of-the art instrumentation including RIMS, NanoSIMS, FE-SEM/EDS.
- Align and operate laser systems for use in laser spectroscopy and resonance ionization, especially tunable laser systems with emphasis on laser-atom interactions.
- Develop and pursue innovative research applying mass spectrometry, with a focus on RIMS, to novel applications.
- Contribute to the conception, design, and execution of advanced research to address problems in cosmochemistry and nuclear materials characterization.
- Develop new measurement techniques to analyze novel samples by RIMS and extend the status quo.
- Collaborate with other scientists and technical personnel to accomplish research goals.
- Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings.
- Perform other duties as assigned.

- Recent PhD in earth sciences, experimental physics, analytical chemistry, or related field.
- Experience preparing and analyzing environmental and anthropogenic samples for radionuclides and stable isotopes ranging in concentrations from trace to high-level.
- Experience in laser systems, ion sputtering and/or laser ablation, ion optical systems, and data acquisition systems.
- Experience in Python, C++, or similar programming language for data processing.
- Ability to develop independent research projects as demonstrated through publication of peer-reviewed literature.
- Familiarity with the field of mass spectrometry, and understanding of the current state of knowledge in this field.
- Ability as an innovative experimentalist with experience in experimental design, techniques, and execution, and the ability to work independently as well as in multidisciplinary research teams.
- Proficient written and verbal communication skills necessary to deliver presentations and prepare written publications, and reports.

Desired Qualifications
- Publication record in peer-reviewed literature with experience presenting research results to a large audience.
- Experience in statistical analysis applied to uncertainty quantification.
- Experience programming in Python, C++, or similar environment for hardware control and data acquisition.

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.

However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process. This process includes completing an online background investigation form and receiving approval of the background check. (This process does not apply to foreign nationals.)

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