ORNL: Postdoctoral Research Associate in Super-Resolution Inelastic Neutron Scattering

Oak Ridge, USA

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 for more than 3,000 visiting scientists. 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 Neutron Sciences Directorate at Oak Ridge National Laboratory (ORNL) invites applications for a Postdoctoral Research Associate with strong experience and expertise in either scattering sciences, or super-resolution imagery algorithm developments. This project is a collaboration between the Neutron Data Analysis and Visualization Division (NDAV) and the Computer Science and Mathematics Division (CSMD) at ORNL, and it benefits from interactions with the instrument teams in the Neutron Science Directorate (NScD). The project goal is to improve capabilities for the inelastic Time-of-Flight neutron instrument suite at SNS through computing.

Job description

Major Duties/Responsibilities

Developing Super-resolution Inelastic Neutron Scattering (SR-INS) by applying super-resolution imagery techniques to 4-D single crystal datasets and 2-D powder datasets measured at the direct geometry neutron chopper spectrometers at the Spallation Neutron Source (SNS). We are seeking self-starters, willing to develop expertise in neutron data analysis, computational imagery, statistical analysis, and optimization techniques. The position is integrated in an interdisciplinary research team between NDAV, CSMD, and QCMD with expertise in inelastic neutron scattering, Monte-Carlo neutron ray-tracing simulations, statistical modeling, optimization, high-performance computing, and development of data reduction and analysis techniques. Duties also include algorithm developments, scientific data analysis, INS neutron experiments, publishing results, and developing software.

Responsibilities will include:

  • Develop computing tools to apply super-resolution imagery algorithms to inelastic neutron scattering datasets measured at direct geometry neutron chopper spectrometers
  • Perform neutron scattering experiments and analyze data taking advantage of the SR-INS techniques
  • Responsible for presenting and reporting research results and publishing scientific results in peer-reviewed journals in a timely manner
  • Ensure compliance with environment, safety, health and quality program requirements
  • Maintain strong commitment to the implementation and perpetuation of values and ethics
Requested Profile

Qualifications Required

Basic Qualifications:

  • A PhD completed within the last 5 years in physics, applied physics, applied math, material science, chemistry, or other relevant fields from an accredited institution.
  • An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals
  • Desire to learn and adopt new tools and technologies
  • Candidates should be self-motivated, have good interpersonal, communication and presentation skills and a demonstrated ability to interact effectively with colleagues at all levels. The ability to work as a member of a multi-disciplinary team is a critical asset.
  • Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience
  • Motivated and safety conscious
  • Ability to set priorities, multi-task and adapt to ever changing needs with the proven ability to function well in a fast-paced environment
  • Ability to work with a measure of autonomy and a willingness to participate creatively in a collaborative team environment
  • Ability to work on multiple tasks in a limited amount of time and to independently set priorities to accomplish multiple tasks to meet deadlines

Additional Information:
Applicants must have received their degree within five years of the date of application and must complete all degree requirements before starting their appointment. Certain exceptions may be considered. Appointments will initially be for 24 months with a possibility of an extension of up to 12 months depending on funding and performance.

Preferred Qualifications:

  • Expertise in analysis of scattering data and/or imagery data
  • Experience with direct geometry neutron chopper spectrometers
  • Experience with super-resolution imagery algorithm development
  • Scientific computing skills such as statistical modeling, optimization, and/or DFT simulations
  • Knowledge and experience in one or more programming languages such as: Python, C++, C, Fortran, MatLab, and Unix/Shell
