Oak Ridge, Tennessee, USA


The Diffraction Group in the Neutron Scattering Division (NSD) of the NScD at Oak Ridge National Laboratory has an immediate opening for a postdoctoral position focused on the modeling of local atomic structure in nanophase and nanostructured materials. Particular attention will be focused on linking surface chemistry, particle morphology, and “internal” crystal structure to the properties of functional nanocrystals, including during their use in industrial processes. Successful candidates will work within a collaborative team to develop and apply new data reduction and structure refinement methodologies, including towards in situ data monitoring and analysis. This position will allow postdoctoral scientists to develop expertise, broaden experience and to interact with a diverse set of leading scientists working and visiting ORNL’s neutron facilities.

Description of Institution

The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator based neutron source. Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov

Job description

Major Duties/Responsibilities

  • Employ experiments and atomistic modeling to study, understand, and optimize structure-property relationships in nano and disordered crystalline materials.
  • Implement and utilize novel data reduction and data modeling algorithms to further develop the performance of the powder diffraction instruments, including towards in situ data monitoring and analysis.
  • Publish scientific papers resulting from this research and present results at appropriate national and international meetings
  • Physical requirements for this job include the use of hand and eye protection gear, kneeling, sitting for extended periods of time, working with sample environment equipment, and possible exposure to ionization radiation normally associated with operation of neutron scattering instruments for scientific research
  • Ensures compliance with environment, safety, health and quality program requirements
  • You will be expected to commit to ORNL’s Research Code of Conduct by holding yourself and others to the highest scientific, professional, and ethical standards in a manner that fosters mutual respect and enhances the reputation of the individual researcher, his/her colleagues, and the Oak Ridge National Laboratory in its mission to address the Department of Energy’s and the nation’s scientific and technical challenges.

ORNL Benefits
