This position seeks to fill a research role in chemical processes and energy systems with an expert in computational modeling and simulation theory and application. Preference is given to candidates with expertise in the modeling and analysis of chemical processes and systems over a wide range of scales. The successful candidate will conduct research independently but collaboratively primarily in reactor scale modelling and chemical kinetic modelling. Experience with commercial chemical reactor modeling packages (COMSOL, STARCCM/gPROMS, Fluent, Barracuda etc), open source codes (OPENFOAM), and/or MFiX will all be considered favorably.  Direct experience modeling fixed bed, moving bed, fluid bed or riser-based chemical reactors and working knowledge of both finite volume and finite element methods will be a positive.

Candidates should have a demonstrated record of technical accomplishment in the field of modeling and simulation and defining and implementing research visions that unify and guide the activities of multi-disciplinary researchers. Experience with validation of models and working with experimentalist is also of interest.  The chosen candidate is expected to contribute to major programs in the areas of biomass conversion to fuels and co-products, chemical manufacturing, CO2 capture and utilization, and other clean energy chemical processes.

The position is in the Manufacturing Sciences Division at Oak Ridge National Laboratory (ORNL).  The successful candidate will opportunities to collaborate with a diverse range of staff across ORNL.  The successful candidate will be expected to serve as the technical communicator to sponsors as well as interface with collaborating scientists at other national labs, industry, and universities. Representative activities include: developing strategies for defining and meeting long term goals relevant to the U.S. Department of Energy (DOE) programs, engaging DOE sponsors, developing R&D proposals, providing technical and strategic vision and leadership in developing a portfolio of cross-cutting modeling and simulation research by coordinating with a diverse multi-disciplinary team.

Oak Ridge National Laboratory (ORNL) is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security. Our diverse capabilities span a broad range of scientific and engineering disciplines, enabling the Laboratory to explore fundamental science challenges and to carry out the research needed to accelerate the delivery of solutions to the marketplace. ORNL is nestled in the beautiful foothills of the Appalachian Mountains with an abundance of opportunities to enjoy outdoor activities on the surrounding lakes, rivers, and trails.  Staff enjoy a four-season climate and affordable living in the Oak Ridge/Knoxville area which has a lively music, theater, and restaurant scene.

Major Duties/Responsibilities:

  • Conduct pioneering research in modeling and simulation of complex chemical processes including catalyst systems, chemical processes, and thermochemical/electrochemical conversion processes for renewable clean energy
  • Develop new projects and extended proposals beyond the scope of currently sponsored project(s)
  • Possess excellent communication skills and be able to proactively communicate with other scientists/engineers internally and externally to build the teams
  • Have a track record of excellent mentorship of postdocs/students.
  • Be responsible for preparing, presenting, and reporting research results and publishing scientific results in key peer-reviewed journals
  • Be responsible for budget planning and management
  • Ensure compliance with environment, safety, health and quality program requirements.
  • Maintain strong dedication to the implementation and perpetuation of values and ethics.

Qualifications Required:

  • A PhD in Chemical Engineering, Mechanical Engineering, Computer Science or related discipline with experience in modeling and simulation of applied engineering processes and systems.
  • A record of excellence in modeling and simulation research as evidenced through peer-reviewed journal publications, patents, or industry/commercial impact
  • Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience
  • Ability to work collaboratively in a team environment and interact effectively with a broad range of colleagues
  • Ability to function well in a dynamic research environment, set priorities to accomplish tasks on time, and adapt to ever-changing needs

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.
