CAMS Radiocarbon Group Sample Characterization and Preparation Lab Scientist

Lawrence Livermore National Laboratory
Livermore, CA 94550

We have an opening for a Scientist to conduct moderately complex analytical characterization, isolation, and pretreatment in support of research and development using natural abundance 14C as an environmental carbon tracer and geochronometer. This position is in the Natural Radiocarbon Group at the Center for Accelerator Mass Spectrometry (CAMS) in the Atmospheric, Earth & Energy Division.

This position will be filled at either the SES.1 or SES.2 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

In this role you will

  • Pretreat samples submitted to the CAMS Radiocarbon Graphite Lab for various analyses, with the predominant processing being of samples for radiocarbon analyses, and the processing involving routine (e.g., load and combust) to moderately complex (e.g., chemical pretreatment) to complex (e.g., separation via HPLC or cryogenic purification) sample pretreatment methodologies.
  • Process pretreated samples through graphitization procedures to produce samples in the form that is suitable for measurement in the 14C AMS systems.
  • Develop, refine, and implement moderately complex to complex sample pretreatment methodologies involving various wet chemistry, physical procedures, or HPLC separation for the extraction and purification of targeted sample fractions relevant to the research being undertaken.
  • Collaborate on research projects with CAMS staff and/or outside collaborators.
  • Participate in the training and oversight of new LLNL scientists/postdocs and visiting students/scientists in natural level radiocarbon samples for 14CAMS analyses.
  • Maintain laboratory notebooks and sample preparation logs (hardcopy and electronic) and conduct data analyses relevant to sample preparation laboratory protocols and individual/collaborative research.
  • Participate in the maintenance of laboratory equipment, making repairs and upgrades as necessary and requested, to help ensure that all appropriate materials and equipment are accessible and in working order at all times.
  • Perform other duties as assigned.

Additional job responsibilities at the SES.2 level

  • Participate in the conception and design of moderately complex to complex new experiments and approaches to execute research to address defined problems and emerging challenges in carbon cycle science.
  • Prepare written analyses, verbal briefings, and other products that capture and communicate research results including conference presentations and peer-reviewed journal articles.

  • Bachelor's degree in Earth Science, Chemistry, or related field, or the equivalent combination of education and relevant experience.
  • Proficiency with natural abundance carbon isotopic sample preparation and/or analysis.
  • Experience with lab equipment including centrifuges, heat blocks, lyophilizers, furnaces, vacuum systems and H2/O2 torches.
  • Experience developing, implementing, and following laboratory procedures and protocols, including keeping written and electronic records.
  • Proficient verbal and written communication skills necessary to work effectively in a diverse research environment, give technical presentations, reports, and scientific documents.
  • Proficient computer skills including but not exclusive to EXCEL, WORD, and FileMaker Pro on Macintosh platforms.
  • Ability to work effectively under rigorous and sometimes multiple conflicting deadlines.

Additional qualifications at the SES.2 level

  • Master's degree in Earth Science, Chemistry, or related field, or the equivalent combination of education and relevant experience.
  • Experience in the application of natural abundance 14C analyses to earth science and/or geochronological research, including the interpretation of radiocarbon data in complex environmental settings.
  • Proficiency with natural abundance radiocarbon sample preparation and analysis including isolation, pretreatment, conversion to CO2 and graphite, quantitative gas transfer and purification, and target preparation for AMS radiocarbon analysis.

Qualifications we desire

  • Experience with development and implementation of separation methodologies for target compounds via HPLC or characterization of complex organic carbon mixtures via spectroscopic or other advanced techniques.
  • Willingness to engage and contribute to our inclusive lab culture.

All your information will be kept confidential according to EEO guidelines.
