Job summary

Battelle Energy Alliance seeks a Postdoctoral Research Associate in Computational Geoscience at Idaho National Laboratory to advance reactive transport and THMC simulations. You will work with FALCON and MOOSE to model interactions among fluid flow, heat transfer, geochemistry, and rock properties.

This role emphasizes multi-physics integration and collaborative research on geohydrogen and enhanced geothermal systems.

Qualifications

• PhD in Geoscience, Geochemistry, Engineering, Materials Science, Computational Science, or related discipline.
• PhD requirements must be completed by commencement of appointment and within the previous 5 years.
• Hands-on multiphysics modeling experience using FALCON/MOOSE or similar tools with understanding of porous-media flow and coupled THMC processes.
• Foundations in finite-element methods and nonlinear numerical solution techniques; experience in model verification/validation.
• Scientific programming in C++, Fortran, Python, or MATLAB and ability to develop automated simulation workflows.
• Developing peer-reviewed publication record, effective communication, and ability to conduct independent research within interdisciplinary teams.

Responsibilities

• Develop reactive transport models using FALCON/MOOSE or similar tools, coupling advection, diffusion, dispersion with thermal, hydraulic, and mechanical processes.
• Implement reaction kinetics, porosity, permeability, and fracture-matrix exchange conditions; quantify transport and mass balances.
• Model hydrogen generation and mineral mobilization, evaluate how fluid chemistry influences reaction progress and recovery.
• Couple electrofracturing and electrohydraulic stimulation with reactive transport to assess fracture connectivity and mineral accessibility; simulate circulation and heat extraction in EGS.
• Verify numerical implementations, calibrate and validate models against observations, and assess convergence and uncertainty.
• Automate computational workflows, improve parallel performance, collaborate with experimental teams, publish findings, contribute to proposals.
