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 conduct research in the development of next generation ultra-low density materials using a combination of additive manufacturing and advanced templating techniques. You will actively participate in the design, synthesis and development of functional photoresists and will be expected to characterize the reaction kinetics of various photo-polymerization processes, providing both experimental data and validation in support of an on-going effort to develop predictive computational physics models. This position is in the Advanced Materials Synthesis group within the Materials Science Division.

Essential Duties
- Formulate, synthesize and characterize advanced or unique photoresists for high resolution two-photon lithography (TPP), as well as stereolithography (SLA) based 3D printing.
- Develop methods and/or utilize existing tools to monitor and characterize reaction kinetics related to photopolymerization processes used in additive manufacturing.
- Develop and optimize procedures to degrade or remove 3D-printed polymeric scaffolds.
- Test, monitor and interpret mechanical and thermal properties of 3D printed materials.
- Collaborate with scientists in a multidisciplinary team environment to accomplish research goals.
- 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 broadspectrum of scientists internally and externally to the Laboratory.
- Perform other duties as assigned.

- Recent PhD in Chemistry, Chemical Engineering, Materials Science, or a related field.
- Experience in one or more of the following areas: organic or inorganic chemistry, polymer science, synthesis, additive manufacturing, photochemistry.
- Experience in monitoring chemical reaction kinetics.
- Experience in measuring mechanical and thermal properties of polymeric materials.
- Ability as an innovative experimentalist with a broad range of experience in experimental design techniques and execution.
- Ability to develop independent research projects through publication of peer-reviewed literature.
- Proficient verbal and written communication skills as reflected in effective presentations at seminars, meetings and/or teaching lectures.
- Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.
Desired Qualifications
- Experience or familiarity with stereolithography and the chemistries enabling these technologies.
- Experience with formulating epoxy resins/adhesives, silicones or other elastomers, hydrogels, biopolymers and/or other related network materials.
- Experience with materials characterization using Nuclear Magnetic Resonance, Transmission Electron Microscopy, Scanning Electron Microscopy, X-Ray Diffraction, Fourier-Transform Infrared, Raman, X-ray Photoelectron Spectroscopy.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  Q-level clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

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.
