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.

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 development and application of solvothermal and continuous
flow reactor devices for in situ diffraction and Pair Distribution Function (PDF) studies, primarily at the high-flux neutron total
instrument NOMAD. Emphasis will be placed on synthesis and structure-property optimization of novel energy based
materials, achieved through control and exploitation of disorder, defects, and interfaces in metastable and nanophase
materials. Laboratory characterization and complementary scattering techniques (including small angle neutron scattering,
vibrational spectroscopy, and synchrotron x-ray total scattering, etc.) may also be pursued. The position will allow the
postdoctoral scientist to develop expertise, broaden experience and to interact with a diverse set of scientists working and
visiting ORNL's neutron and nanomaterial science facilities.

Major Duties/Responsibilities
* Employ methods to study and understand the formation, growth and transformation processes of nano- and disordered
crystalline materials with neutron diffraction, neutron PDF analysis, and complementary probes at ORNL.
* Assist in developing solvothermal and continuous flow chemical reaction vessels for time-resolved neutron-based
characaterization of synthesis processes.
* 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.

Qualifications Required
Basic Qualifications:
* Ph.D. in Materials Science, Chemistry, Physics, or other related science field
* Background in structural analysis using crystallographic methods
* Experience with inorganic materials synthesis
* Excellent communication and presentation skills
* Demonstrated ability to interact effectively with colleagues at all levels and in multi-disciplinary teams

Preferred Qualifications:
* Experience in solution phase synthesis, including for nanophase materials
* Previous experience in total scattering (PDF) methods and analysis
* Experience in developing software and/or sample environment for diffraction experiments
* Data modeling and refinement expertise using programs such as TOPAZ, GSAS, Fullprof, PDFGUI and RMCProfile
* Programming proficiency in Python, C++, and/or Fortran

Other Information:
Applicants must have received their PhD within five years of this application and must complete all degree requirements
before starting their appointment.
Please include a Cover Letter and CV with your application. Your cover letter should include the name and contact
information for two professional references. If you are asked to interview, you will be asked to provide a minimum of 2
reference letters for the hiring committee.

Work Directions and Interfaces
This position will report to Katharine Page. Candidate will work closely with research staff and other postdoctoral associates
in NSD and the Center for Nanophase Materials Sciences at ORNL.
