Postdoctoral Research Associate - Machine Learning for Neutron Diffraction

Date: May 11, 2022

Location: Oak Ridge, TN, US, 37803

Company: Oak Ridge National Laboratory

Requisition Id 8012 

Overview: 

Oak Ridge National Laboratory 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.

 

We are seeking two Postdoctoral Research Associates who will support the Single Crystal Diffraction and Powder Diffraction Group in the Neutron Scattering Division (NSD), Neutron Science Directorate (NScD) at Oak Ridge National Laboratory (ORNL). The Spallation Neutron Source (SNS) and the High-Flux Isotope Reactor (HFIR) are world-leading facilities and the scientific center of a diverse, international and inclusive neutron scattering community.

 

As a Postdoctoral Research Associate you will be a member of a team of neutron scattering scientists, computational scientists,­ and engineers at both neutron research facilities as well as enterprise software developers and machine learning experts.

Your research will focus on optimizing and incorporating advanced visualization and neutron data analysis employing machine learning software for scientific studies of magnetism in quantum materials and/or structure of disordered and functional materials.

 

The project will implement state of the art GPU and parallel computing approaches for visual image processing and multidimensional, interactive visualization of neutron data and analysis. It will involve integrating machine learning software onto existing neutron beamlines for sample alignment and for performing scientific research to study structure and magnetism. Neutron techniques will concentrate on neutron powder and single crystal diffraction, complemented by polarized neutron powder diffraction and inelastic measurements. 

 

This position represents an excellent opportunity to deepen understanding of the properties, magnetism and function of materials and utilize machine learning for visualization and analysis of neutron scattering data in a stimulating multidisciplinary environment at ORNL.

 

The two positions are split into two focus areas:

  • Developing visualization and analysis for diffuse scattering data in disordered materials and functional materials.
  • Developing polarized neutron diffraction methods and other relevant neutron scattering techniques to study magnetism in quantum materials

 

Major Duties/Responsibilities: 

  • Apply machine learning software to neutron scattering beamlines to optimize measurements and data analysis
  • Perform neutron scattering experiments and analyze resulting data
  • Publish scientific papers and present results from this research at national and international meetings as appropriate

 

Basic Qualifications:

  • A PhD in physics, chemistry, material science, computational or a related field completed within the last 5 years

 

Preferred Qualifications:

  • Background in elastic/ inelastic neutron scattering and analysis or other diffraction methods and analysis
  • Working knowledge of common or scientific programming languages
  • Familiarity with machine learning approaches
  • Experience with either
    • functional materials and compounds 
    • magnetic materials and measurements
  • Self-motivated, with the ability to work within a multi-disciplinary team environment on scientifically challenging problems
  • Excellent written and oral communication skills
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory 
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs

 

Please submit three letters of reference when applying to this position. You can upload these directly to your application or have them sent to postdocrecruitment@ornl.gov with the position title and number referenced in the subject line.
