Postdoctoral Research Associate, Reactive Transport Simulations of Porous and Fractured Media

Overview:   The Chemical Sciences Division (CSD) at Oak Ridge National Laboratory (ORNL) invites outstanding applications for a postdoctoral research associate to conduct research on simulating precipitation and dissolution of minerals in porous and fractured media. As a postdoc, you will utilize high performance computing at ORNL to work with a team of scientists in the CSD to model experimental tomography and porosity distribution data to improve our capabilities to predict how porosity and permeability evolve in geochemical systems in response to mineral reactions, especially by incorporating models built from realistic mineral reaction processes. The position supports research on understanding and analyzing chemical reactions of rocks and minerals, and resides in the Geochemistry and Interfacial Sciences Group in the Chemical Sciences Division, Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL).  

Major Duties/Responsibilities: 

Conduct independent research using pore-scale simulation approaches of geochemical reactions in idealized and natural porous media Collaborate with ORNL researchers on the design and execution of chemical imaging and reactive transport experiments Present and report research results and publish scientific findings in peer-reviewed journals in a timely manner Ensure compliance with environment, safety, health and quality program requirements Maintain strong commitment to the implementation and perpetuation of values and ethics Basic Qualifications: 

A PhD in Physical Sciences or Chemical Engineering, such as Geology, Geochemistry, Chemistry, Materials Science, or related disciplines completed within the last 5 years Experience in the design and implementation of numerical algorithms in one or more high-level computing languages (e.g., C++, Python) Preferred Qualifications:

Strong background in reactive transport simulation and model development, such as experience with software such as OpenFOAM, Chombo-Crunch Experience with simulating porous systems (especially simulation the pore-scale) and dual porosity systems, such as fractured porous media Record of collaboration with experimentalists, especially comparison to observations of mineral precipitation/dissolution and fluid compositions Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience Excellent record of productive and creative research demonstrated by publications in peer-reviewed journals The abilities to be a self-starter, to work independently and to participate creatively in a collaborative team effort Background in simulating precipitation and dissolution of minerals and effluent water composition Knowledge of methods to model interface: Level-Set, Volume of Fluid, Arbitrary-Lagrangian-Eulerian  method, etc. Strong skills to work with Linux or other Unix-like operating systems Experience working with high-performance computing and hybrid parallelism such as MPI, OpenMP, or CUDA Special Requirement:

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.

Please provide a list of publications when applying for this position.  Three letters of reference are required and can be uploaded to your profile or emailed directly to PSDrecruit@ornl.gov.  Please include the title of the position in the subject line.
