Los Alamos National Laboratory Contaminant/Radionuclide Geochemistry Fate and Transort Postdoc in Los Alamos, New Mexico

What You Will Do

The geochemistry team in the Earth Systems Observation/EES-14 has an immediate opening for an outstanding candidate for a postdoc position. The post-doctoral will participate in experimental research focused on the characterization of the fate and transport of radionuclides and potentially other contaminants under a wide range of geochemical and hydrogeologic conditions (e.g., porous or fractured media, saturated or unsaturated media, and various geochemical environments). Initially the research will be focused on uranium sorption and desorption processes that control uranium transport in support of research pertaining to nuclear waste disposal. The successful candidate will also participate in the translation of the knowledge gained into process models that can be incorporated into state-of-the-art contaminant transport and risk assessment models.

What You Need

Minimum Job Requirements:

  • Experience conducting laboratory and/or field scale experiments to interrogate contaminant transport processes in aquifers.

  • Experience in developing and parameterizing geochemical models to describe the reactive transport behavior observed in such experiments.

  • Experience in modifying thermodynamics-based models (such as those listed above) to account for reaction kinetics is also highly desired.

Desired Skills:

  • Programming experience with Python, Fortran, Java, C/C++, R, and/or MatLab.

  • Demonstrated record of writing proposals.

  • Demonstrated experience writing scientific reports.

  • Experience with chemical and/or radiochemical analytical instrumentation, and specific experience in addressing uranium as a contaminant in groundwater systems.

  • Excellent communication skills as evidence by publication record in respected international journals and presentations at international conferences.

Highly desired skills include :

  • Working with radioactive materials.

  • Experience using geochemical modeling software (such as PHREEQC, Geochemist’s Workbench, MINEQL, EQ3/6) to interpret experimental reactive transport data, including the use of parameter estimation software/features to match data sets and thus parameterize the models.


A Ph.D. in geochemistry, chemical or environmental engineering, environmental chemistry, hydrogeology, or closely related fields. The candidate must have completed all Ph.D. requirements by commencement of the appointment and be within five years of completion of the Ph.D. Candidates may also have previous experience including postdoctoral experience.

Notes to Applicants:

Interested applicants should include a cover letter and a resume. The cover letter should address the candidate experience and how it applies to the opening.

Additional Details:

No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.

New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing.

Notes to applicants: Candidates may be considered for a Director's Fellowship and outstanding candidates may be considered for the prestigious Marie Curie, Richard P. Feynman, J. Robert Oppenheimer, or Frederick Reines Fellowships.
