Join us and make YOUR mark on the World!

Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world‑changing impact advancing science and technology to strengthen U.S. security and promote global stability.

Our mission spans nuclear deterrence, threat preparedness, energy security, and multi‑domain defense, empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

We have an opening for a Postdoctoral Researcher to play a major role in development of novel radio chemical separations, microfluidic techniques and detection for superheavy element experiments. The position will also include collaboration with Lawrence Berkeley National Laboratory’s Heavy Element group for on‑line experiments at the 88‑inch cyclotron. The candidate will apply novel radiochemistry separations to microfluidic systems aimed at studying the chemical properties of copernicium atom‑at‑a‑time.

This position is in the Nuclear and Radiochemistry group of the Nuclear and Chemical Sciences Division.

Depending on your assignment, this position may offer a hybrid schedule, blending in‑person and virtual presence. You may have the flexibility to work from home one or more days per week.

You will

• Develop microfluidic systems to automate and perform radio chemical separations on ultra‑trace levels of radionuclides toward the aim of atom‑at‑a‑time chemistry on‑line at an accelerator.
• Perform radio analytical sample processing and data analysis to interpret results.
• Work with LBNL and LLNL scientists to integrate microfluidic separations with on‑line detection systems and the accelerator facility.
• Prepare and conduct technical presentations for internal and external audiences.
• Document research, publish papers in peer‑reviewed journals, and present results within the DOE community and at conferences.
• Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally.
• Collaborate with others in a multidisciplinary team environment to accomplish research goals.
• Perform other duties as assigned.

• PhD in Nuclear Chemistry, Nuclear Physics, Nuclear Engineering, Radiochemistry, Chemical Engineering, or related field.
• Experience with laboratory instrumentation and associated software controls and designing, assembling, and running nuclear science experiments based on radio chemical or nuclear chemistry methods.
• Experience with charged‐particle and gamma‐ray detectors and radiation counting and their associated data analyses.
• Experience with microfluidic systems or similar separation/chromatography systems, such as LC and HPLC.
• Ability to safely work with radioactive materials (> 100 micro Curie).
• Ability to develop experimental methods, separation techniques, and analysis approaches needed to collect and isolate radioactive isotopes produced at accelerator facilities.
• Experience with radionuclide separation methods, such as solvent extraction and ion exchange.

Qualifications We Desire

• Inorganic or organic synthesis experience especially in the design of new molecules or ligands.
• Experience running chemistry or physics experiments at accelerator facilities.
