Pacific Northwest National Laboratory Post Doc Research Associate - Environmental Signatures Mass Spectrometry in RICHLAND, Washington

Organization and Job ID

Job ID: 310644

Directorate: Energy and Environment

Division: Earth Systems Science

Group: Subsurface Science & Technology

Job Description

Development of method/techniques for the isotopic characterization of small samples of lanthanides, actinides, and other elements.

The Environmental Signatures group at PNNL is seeking applications for a Post-Doctoral Research Associate position in isotopic mass spectrometry. This opening is to support the goals of the group/division, which broadly encompasses impacts from anthropogenic processes (including investigations of contaminant fate and transport, nuclear waste storage, and carbon dioxide sequestration) as well as National Security applications such as nuclear safeguards.

The candidate should have significant, hands-on experience in TIMS (P-TIMS and/or N-TIMS) or MC-ICP-MS. Pertinent additional experience would include actinide and/or lanthanide analyses, PGE isotope ratio measurements, measurements of the isotopic variations of the transition elements, and noble gas mass spectrometry. Additional skills that would be of value include clean lab work, design or modifications of ion emitter or ion detection systems, separations work using ion or solvent exchange, or distillation, and development of laser ablation (LA-ICP-MS) or LA-LIBS methods.

The successful candidate will work as part of a multi-disciplinary team and will have access to state-of-the-art research equipment within several laboratories at PNNL, including a suite of seven multicollection mass spectrometers and associated supporting analytical instruments and facilities. The successful candidate will be expected to enthusiastically contribute to the development of proposals for future research funding. Applicants must be willing to learn and employ safe techniques for handling hazardous materials. Candidates must be able to work with colleagues in a laboratory environment on the implementation of experimental procedures.

The position is immediately available for 12-24 months, with the potential for an additional 12 months or transition to a permanent position, dependent upon available funding and sustained performance.

The candidate is expected to have a Ph.D. (or soon acquire one) in geochemistry, isotope geology, analytical or nuclear chemistry, or a related field. The incumbent must have experience working in a wet-chemistry laboratory around potentially hazardous acids, bases, and materials. Candidates are expected to be proficient with standard office software, such as Microsoft Excel and Word. Excellent verbal and written communication skills are also required and must be demonstrated via a strong publication record in peer-reviewed journals.

Minimum Qualifications

Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.
