Actinide Isotope Signatures - Research Scientist

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 Research Scientist to develop and pursue innovative research in the identification of actinide isotope signatures in environmental samples and nuclear materials with applications to problems in nuclear forensics and proliferation detection.  You will investigate the behavior of U-series and Pu-series nuclides during material production processes through isotopic analysis by MC-ICP-MS or TIMS.  The position is in the Chemical and Isotopic Signatures group within the Nuclear and Chemical Sciences Division

Essential Duties
- Independently develop and pursue advanced innovative research in actinide decay-series isotope measurements of environmental samples and nuclear materials addressing complex problems in nuclear forensics and proliferation detection
- Establish new analytical protocols and techniques for high-purity separation of actinides from complex sample matrices and isotopic analysis by magnetic sector multi-collector mass spectrometry
- Lead technical efforts with responsibility for budgets, schedules, deliverables and resource allocation
- Collaborate with multi-disciplinary teams of scientists and technical personnel to accomplish research goals
- Prepare research proposals for agencies that fund research on nuclear science
- Document and publish research results in peer-reviewed scientific publications and present results at external conferences, seminars and/or technical meetings
- Perform other duties as assigned

- Ph.D. in Geochemistry, Chemistry, or related field, or the equivalent combination of education and related experience.
- Advanced knowledge and significant experience in purification of actinides from complex matrices for MC-ICP-MS or TIMS analysis of isotopic composition
- Advanced knowledge and significant experience in multi-collector isotope ratio mass spectrometry for determination of isotopic composition and concentration using isotope dilution methods
- Significant experience in the interpretation and modeling and of actinide decay-chain disequilibria as a chronometer of natural and/or nuclear fuel cycle processes
- Ability to develop independent research projects as demonstrated through publication of peer-reviewed literature
- Advanced verbal and written communication skills necessary to work in a multidisciplinary team environment, author technical and scientific reports and publications, and deliver scientific presentations
- Initiative and interpersonal skills necessary to work in a collaborative, multidisciplinary team environment

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.
