Group Leader, Radiation Effects & Microstructural Analysis

Date: Nov 10, 2022

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 8312 


We are seeking a Group Leader for the Radiation Effects & Microstructural Analysis Group in the Materials in Extremes Section in the Materials Science and Technology Division (MSTD) in the Physical Science Directorate (PSD) at the Oak Ridge National Laboratory (ORNL).  The group conducts fundamental and applied materials research for fission and fusion energy, space exploration and isotope separation, in close collaboration with Fusion Energy Division, Nuclear Energy and Fuel Cycle Division, and other organizations in ORNL. The main emphases of research are the effects of energetic radiation on microstructural evolutions, resulting property changes, and the underlying physical processes. The group is responsible for operation of the Low Activation Materials Development and Analysis (LAMDA) laboratory, the signature facility of ORNL for nuclear materials science research.


As a group leader, you will manage and mentor group members including research staff, technical staff, post-doctoral fellows and students.  You will be responsible for promoting and maintaining a culture with high ideals for safety, security and ethics.  As a science leader, you will lead multi-disciplinary and multi-organizational teams to develop world-leading research programs, execute world-leading research projects and communicate project results to the international research community.  As a researcher, you will employ state-of-the-art technology and research equipment to advance the science and understanding of the effects of radiation in materials, ultimately to enable the next generation of nuclear power, fusion energy, and other power systems.  Example research topics:

  • Effects of neutron irradiation on engineering and exploratory materials for advanced nuclear reactors and future fusion energy
  • Development of nanostructured alloys and innovative alloy manufacturing processes for enhanced radiation tolerance
  • Development of novel fuel breeding materials for fusion reactors
  • Fundamental processes of radiation damages in metals, alloys, ceramics, and composites


Major Duties/Responsibilities: 

  • Group leader is responsible for managing and mentoring the group (~10%) but also developing and leading a relevant research portfolio (~90%)
  • Directing and oversight of operation of LAMDA laboratory
  • Lead the preparation of research proposals
  • Coordinate and/or conduct research
  • Communicate and coordinate experimental results with other organizations to facilitate collaborations
  • Present and report research results and publish scientific results in peer-reviewed journals in a timely manner
  • Exceed expectations for the safe conduct of research.  Ensure compliance with environment, safety, health and quality program requirements
  • Maintain strong dedication to the implementation and perpetuation of values and ethics


Basic Qualifications:

  • A PhD in Materials Science, Nuclear Engineering, Physics or a related discipline and a minimum of 6 years of experience
  • Background studying radiation effects, microstructural characterization, and/or mechanical properties


Preferred Qualifications:

  • An outstanding record of productive and creative research as demonstrated by publications in peer-reviewed journals
  • Demonstrated success in proposing research
  • Experience writing successful proposals to government sponsors
  • Demonstrated extensive knowledge on radiation effects on materials
  • Demonstrated extensive knowledge on microstructural characterization
  • Demonstrated extensive knowledge on material challenges in fusion and fission energy
  • Experience with post-irradiation evaluations of nuclear materials in radiological laboratory
  • Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience
  • 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
