Pay Range

$118,884 Annually

This is the lowest to highest salary we in good faith believe we would pay for this role at the time of this posting. An employee's position within the salary range will be based on several factors including, but not limited to, specific competencies, relevant education, qualifications, certifications, experience, skills, seniority, geographic location, performance, and business or organizational needs.

We have an opening for a Postdoctoral Researcher to play a major role in development of novel radiochemical 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. You 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.

You will

• Develop microfluidic systems to automate and perform radiochemical separations on ultra-trace levels of radionuclides towards the aim of atom-at-a-time chemistry on-line at an accelerator
• Perform radioanalytical 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 radiochemical 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 nanoCurie)
• 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.

All your information will be kept confidential according to EEO guidelines.
