Job Description
We are excited to offer an opportunity for a Postdoctoral Researcher with expertise related to the Mechanics of Geomaterials to work on computational and experimental assessment of geologic formations to inform design and safety assessment of borehole repository for nuclear waste.
This position is in the Atmospheric, Earth & Energy Division, Computational Geosciences Group
In this role you will
- Analyze available experimental data and identify and/or develop suitable constitutive model forms to describe strength, compaction, creep, and damage in geomaterials.
- Use numerical optimization methods to parameterize complex material models based on available (limited, noisy, variable) data and physical constraints.
- Use tuned constitutive models to assess borehole stability under various in-situ stresses and thermal load conditions.
- Interpret wellbore log data to inform representations of natural faults and fractures.
- Conduct verification/validation of material models and numerical simulations.
- Design and conduct experiments to characterize the strength/creep of Geomaterials and other composite materials.
- Interface with experimentalists from other research groups to accurately interpret experimental data and inform prioritization of new experiments to reduce modeling uncertainty.
- Present original research in conferences and publish in peer-reviewed journals.
- Perform other duties as assigned.
Qualifications
- Experience with large-deformation solid mechanics, such as models for creep, damage, rate-effects, or thermal effects.
- Relevant experience in geology, (e.g. minerology, hydrogeology), geothermal or petroleum engineering
- Experience with mesoscale simulation, experimental characterization or continuum modeling of porous, granular, brittle, or heterogeneous materials.
- Experience with optimization methods for parameterization of physics models
Qualifications We Desire:
Any of these would be useful, a candidate is not expected to have all of these qualifications
- Experience with large-deformation solid mechanics, such as models for creep, damage, rate-effects, or thermal effects.
- Relevant experience in geology, (e.g. minerology, hydrogeology), geothermal or petroleum engineering

Site 300
Site 300 is an experimental test site operated by LLNL. Situated on 7,000 acres in rural foothills approximately six miles southwest of downtown Tracy and 15 miles southeast of Livermore, Site 300 hosts approximately 200 employees with expertise in such fields as engineering, chemistry, biology, and environmental restoration. Employees assigned to work at Site 300 may be exposed to the organism that causes San Joaquin Valley Fever (coccidioidomycosis ).
Security Clearance
None required. However, this position involves U.S. Export Control; this work must be performed by a U.S. person (U.S. citizen, U.S. lawful permanent resident, U.S. national, or U.S. protected individual (e.g., refugee, asylee)).
If your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process. This process includes completing an online background investigation form and receiving approval of the background check. (This process does not apply to foreign nationals.)
