The Chemical Sciences Division (CSD) at Oak Ridge National Laboratory (ORNL) invites extraordinary 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 work with scientists in the Chemical Sciences Division to model experimental aqueous solution chemistry, tomography and porosity distribution data taken in rock cores reacted with aqueous fluids and CO2, and improve our capabilities to predict how porosity and permeability evolve by incorporating process-based models of geochemical reactions. The position relates to research on understanding and analyzing chemical reactions of rocks and minerals in the subsurface, and resides in the Geochemistry and Interfacial Sciences Group in the Chemical Sciences Division (CSD), Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL).  

Major Duties/Responsibilities 

  •  Conduct independent research using pore-scale and/or volume-averaged simulation approaches of geochemical reactions in porous and fractured rock cores
  • Collaborate with ORNL researchers on the design and execution of chemical imaging experiments and reactive transport simulations
  • 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 dedication to the implementation and perpetuation of values and ethics

Basic Qualifications 

  • A PhD in Physical Sciences or Chemical Engineering, such as Geology, Geochemistry, Hydrology, Chemistry, Materials Science, or related disciplines completed within the last 5 years

Preferred Qualifications

  • Strong background in reactive transport simulation in porous media and geochemistry
  • Experience with modeling dual porosity systems, such as fractured media (pore scale or/and continuum scale simulations)
  • 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
  • Ability to function well in a dynamic research environment, set priorities, multi- task and adapt to ever changing needs
  • Background in simulating precipitation and dissolution of minerals and effluent water composition
  • Basic experience with combining experimental data with models, defining initial parameters for simulations from experimental findings
