The Chemical Sciences Division (CSD) in the Physical and Life Sciences (PLS) Directorate is seeking a Research Scientist to perform advanced research in nonproliferation nuclear forensics. The successful candidate will contribute to funded research projects addressing problems in both pre- and post detonation nuclear forensics including fallout formation, resonance ionization mass spectrometry, identifying forensic signatures in material ranging from fallout debris to uranium oxide compounds. The candidate must be able to work independently as well as in multidisciplinary research teams. We are seeking a creative and flexible individual who meets the scientific requirements of this posting and whose skills are aligned with our strategic growth opportunities. The individual will report to the Group Leader for Chemical and Isotopic Signatures.

- Independently develop and pursue advanced research to understand the mechanisms and timescales relating to fallout formation, the development and persistence of chemical and isotopic nuclear forensic signatures, and the abundance and isotopic composition of actinides, fission products and activation products in fallout debris.
- Independently develop and pursue advanced research to develop and apply state-of-the-art instrumentation, including resonance ionization mass spectrometry and laser ablation inductively coupled mass spectrometry, to nuclear forensic analysis.
- Contribute to the conception, design, and execution of research to address complex problems.
- Collaborate with other scientists and technical personnel, including providing oversight, to ensure project deliverables are met and ensure smooth operations and technical excellence.
- Communicate research progress by means of publications, presentations, and internal reports.
- Analyze, report, and present scientific results at seminars, technical meetings, national and international conferences.
- Maintain effective communications with scientific efforts internal and external to the Laboratory.
- Interact with senior project staff and management to influence programmatic decisions.
- Develop research activities relevant to the needs of Laboratory programs and/or external funding agencies.
- Coordinate activities of supporting technical personnel.
- Perform all assignments in accordance with ES&H, security and business practice requirements and policies.

- Write proposals, secure funding, and establish independent research projects.

- PhD in Geochemistry or related field or equivalent level of demonstrated knowledge.
- Demonstrated advanced understanding of the isotope geochemistry of uranium ore deposits.
- Demonstrated advanced knowledge and significant experience with inductively coupled mass plasma spectrometry and chromatography.
- Demonstrated advanced knowledge of nuclear forensic analysis of complex materials.
- Demonstrated advanced understanding and significant experience with mass spectrometric analysis of radiogenic and heavy stable isotope systems.
- Demonstrated proficiency with chromatography and mass spectrometry for Cr isotopes.
- Demonstrated capability as an innovative experimentalist with experience in experimental design, techniques, and execution.
- Demonstrated quantitative analytical capability.
- Experience in writing reports, publications, and proposals.
- Advanced verbal and written communication skills to collaborate effectively in a team environment, present and explain technical information, and provide advice to LLNL and project management.
- Ability to respond quickly to diverse and shifting demands.
- Record of peer-reviewed publications.
- Ability to work independently as well as in a team environment.

- Familiarity with actinide chemical separation and mass spectrometry.
