Postdoctoral Research Staff Member

Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a Postdoctoral Researcher to play a major role in developing isotope harvesting approaches at existing accelerator facilities that will eventually be used at the Facility for Radioactive Ion Beams (FRIB). You will develop techniques for harvesting radioactive isotopes at Michigan State University‚€™s National Superconducting Cyclotron Laboratory (NSCL) and other accelerator facilities, and will investigate the feasibility of performing cross-section measurements of importance to s-process nucleosynthesis and stockpile stewardship with these samples.This position is in the Nuclear & Radiochemistry group of the Nuclear & Chemical Sciences Division.

Essential Duties
- Develop experimental methods, separation techniques, and analysis approaches needed to collect and isolate radioactive isotopes produced at accelerator facilities.

- Perform sample and data analysis and interpret results.

- Design experiments at existing accelerator facilities and apply for beam time as appropriate to perform tests of harvesting techniques.

- Apply expertise in experimental nuclear science to help solve a variety of programmatic challenges in national security.

- Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings.

- Perform other duties as assigned.


- Recent PhD in nuclear chemistry, nuclear physics, nuclear astrophysics, nuclear engineering, radiochemistry, or related field.

- Experience with radionuclide separation methods, such as liquid-liquid extraction, ion exchange chromatography or solvent extraction.

- Experience with charged-particle and gamma-ray detectors and radiation counting.

- Hands-on experience in designing, assembling, and running nuclear science experiments based on radiochemical or nuclear chemistry methods.

- Experience with data analysis and interpretation.

- Demonstrated ability to work independently and as part of a multi-institution collaboration.

- Demonstrated fundamental written and verbal communication skills necessary to deliver presentations and prepare written reports.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.

Anticipated Clearance Level: None.

Note: This is a two-year Postdoctoral appointment with the possibility of extension to a maximum of three years. Eligible candidates are recent PhDs within five years of the month of the degree award at time of hire date.
