Job Description

We are seeking a Secondary Ion Mass Spectrometry and Nuclear Forensics Postdoctoral Researcher with a strong interest in conducting nuclear forensics research using dynamic secondary ion mass spectrometry (SIMS). Our group has a long history in SIMS, including research using our CAMECA ims-3f, ims-4f and NanoSIMS 50, as well as other SIMS instruments. In the coming years, we will obtain two new SIMS instruments, including an ims-7f GEO, which will be central to this postdoctoral fellowship.

The primary focus will be on the analysis of nuclear debris resulting from a nuclear detonation. You will have the opportunity to help shape this research.

In this role you will:

  • Become proficient at SIMS analysis.
  • Perform and interpret compositional analyses of nuclear materials and debris samples.
  • Conduct fundamental research into the formation of nuclear debris and debris chemistry.
  • Function as an independent researcher with a high-level of attention to detail.
  • Work with an integrated, interdisciplinary team.
  • Maintain professional and institutional visibility through participation in conferences.
  • Document and publish research results in peer-reviewed scientific or technical journals.
  • Perform other duties as assigned.


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance, which requires U.S. Citizenship.
  • PhD in chemistry, geology, or related field.
  • Experience applying isotope ratio mass spectrometry to address research questions.
  • Experience with spatially resolved analytical techniques.
  • Experience in statistical analysis of data including uncertainty quantification or sensitivity studies.
  • Experience in verbal and written communication of technical information.
  • Interpersonal skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff.

Qualifications we desire:

  • Experience with operation of a SIMS or similar instrument
  • Experience processing, interpreting, and presenting spatially resolved data.
