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 to join the Center for Accelerator Mass Spectrometry (CAMS) to work within the natural-radiocarbon group in support of new and ongoing projects in terrestrial carbon cycle science including the development of compound-specific 14C measurements to advance understanding of soil carbon storage and dynamics. Your research will include studies of: the origin, transport, stabilization, and transit time of soil organic matter (SOM); quantification of components of SOM and their specific turnover times, including soil physical and chemical fractions and compound-specific or compound class quantification and characterization; identification of carbon sources for soil carbon fluxes; and data synthesis and modeling. This position is in the Atmospheric, Earth & Energy Division.
- Conduct creative and independent research as a member of a multi-disciplinary team, collaborate in technique development and sample analysis in experimental programs in terrestrial carbon cycling.
- Manage and assist in the flow of natural 14C samples through the CAMS laboratory, and participate in technique development, AMS operation, and data analysis as part of the overall activity of the natural-radiocarbon research group.
- Develop and implement workflows for 14C measurements of targeted compounds and compound classes from soils and soil fractions/extracts.
- Document and publish research results in peer-reviewed scientific journals and present results at international conferences, present seminars and/or presentations at technical meetings.
- Ability to conduct fieldwork and travel to field sites.
- Collaborate with others in a multidisciplinary team environment to accomplish research goals.
- Perform other duties as assigned.
- Ph.D. in soil biogeochemistry, geochemistry, environmental chemistry, or a related discipline.
- Experience in soil carbon cycle research including soil organic matter characterization using physical and chemical separation techniques for chemical and isotopic analysis.
- Quantitative understanding and interpretation of stable isotope or radiocarbon analyses in carbon cycle studies with a focus on belowground processes and soil organic matter characterization.
- Ability to perform soil carbon fieldwork (e.g., soil, root, or soil water sampling; CO2 or CH4 flux measurements).
- Ability to work effectively in a multi-institutional, multi-disciplinary research environment, both independently and as a team member.
- Proficient verbal and written communication skills to collaborate effectively in a team environment and to present and explain technical information.
- Practical experience in preparing samples and applying low-level 14C measurements to environmental samples.
- Practical experience in preparing samples for compound class or compound-specific characterization with 14C and/or 13C and in interpreting these data in the context of terrestrial biogeochemistry.
- A strong interest in advancing understanding in interactions between plants, minerals, and microbes in driving soil carbon storage and cycling with and in developing applications of compound-specific 13C or 14C measurements to these science areas.
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.
