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 Biogeochemistry Postdoctoral Researcher to develop and pursue innovative research in the analysis of actinide and stable metal isotopes in environmental samples for environmental biogeochemistry . You will perform isotopic analyses utilizing MC-ICP-MS to investigate the behavior of actinides, and to identify and develop stable metal isotope signatures relevant to understanding the cycling and transport of metals and radionuclides at several contaminated field sites in the US and UK. This position is in Environmental Isotopic Signatures group of the Nuclear and Chemical Sciences Division. Essential Duties - Develop and pursue innovative research addressing advanced environmental isotope geochemistry and radiochemistry. - Determine the concentration and isotopic composition of actinide decay-series nuclides and other metal elements in complex matrices (including environmental samples) using high-purity separation chemistry and multi-collector mass spectrometry. - Design and conduct soil column experiments that reveal processes controlling radionuclide transport and cycling in the environment. - Assist in the collection of surface water, soil, and groundwater samples from field sites in the US. - Document and publish research results in peer-reviewed scientific journals and present results at international conferences, present seminars and/or presentations at technical meetings. - Collaborate with other scientists and technical personnel to accomplish research goals. - Perform other duties as assigned. Required Skills and Qualifications - Recent PhD in Earth Sciences, Chemistry, Nuclear Engineering, Geology, Radiochemistry or related field. - Experience in multi-collector isotope ratio mass spectrometry for determination of isotopic composition and of concentration using isotope dilution. - Experience conducting laboratory experiments (batch, column, etc.) to quantify sorption and transport behavior of metals in soils and single minerals. - Excellent verbal and written communication skills necessary to work in a multidisciplinary team environment, author technical and scientific reports and publications, and deliver scientific presentations. - Documented publication record in peer-reviewed literature with experience presenting research results to a large audience. - Proficient verbal and written communication and interpersonal skills to collaborate effectively in a multidisciplinary team environment and present and explain technical information. Desired Skills - Experience in purification of trace actinides and other elements from complex matrices for mass spectrometric analysis of isotopic composition. - Experience performing laboratory experiments to quantify biogeochemical processes controlling radionuclide and metal transport behavior - Experience sampling soil and groundwater from field sites in the US Proficiency with using one or more the following tools: XRD, SEM, TEM, GC, liquid scintillation counting, mass spectrometry, NMR.

Pre-Placement Medical Exam: A job related pre-placement medical examination may be required.
