Post Doctorate RA - Geophysical Modeling
Job Description
The Detection Systems Group at Pacific Northwest National Laboratory (PNNL) seeks candidates with experience in multi-phase subsurface flow and reactive transport modeling to contribute to one or more areas of nuclear monitoring research
- Development and application of conceptual-mathematical models for subsurface flow and reactive transport following underground nuclear explosions.
- Experiments of gas and debris transport through fractured porous media.
- Studies of dynamic noble gas background evolution in various geologies.
- Building integrated signature simulation capabilities tying nuclear source models with dynamic subsurface flow and reactive transport models to support nuclear explosion monitoring studies.
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.
U.S. citizenship required.
Preferred Qualifications
Ideal candidates will have experience in areas of geology, hydrology, or geophysics. Demonstrated experience in one or more of the following is preferred:
