Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is essential to innovation and creativity for continued success of the Laboratory’s mission.

Job Description

The Seismology Group at LLNL has an opening for a Postdoctoral Staff Member to do original and independent research to support the Source Physics Experiment (SPE) and other Geophysical Monitoring Programs (GMP). The applicant will work on all aspects of the Source Physics Experiment (SPE) Phase III, also known as the Rock Valley Direct Comparison (RV/DC) Experiment. A focus of RV/DC is to improve our understanding of the physics underlying signature differences between explosions and shallow earthquakes. The applicant will also work with the broader GMP team and its extensive seismic research and software databases. This position is in the Seismology Group within the Atmospheric, Earth, and Energy Division (AEED) in the Physical and Life Sciences (PLS) Directorate.

In this role you will

  • Conduct original and independent research, in collaboration with other LLNL researchers into improving our understanding of earthquakes and explosions, with the goal of improving capabilities to discriminate between seismic source types.
  • Assist in the development, validation, and application of physics-based seismic source models of explosions and earthquakes, and their use in analyzing data as well as predicting signatures from future events.
  • Assist in the sensor network design, signature collection and analysis of seismic and geophysical data from the RV/DC experiment and other relevant explosion and earthquake experiments, including legacy nuclear explosion data.
  • Explore new technologies and data analysis techniques that may improve the ability to detect, locate, identify, and characterize explosions in a background of natural earthquakes and other seismic sources.
  • Present research at meetings, as well as write, illustrate, and publish results in peer reviewed journals.
  • Work as part of a scientific team and interact with GMP and other researchers to design and implement research projects, while coordinating program requirements and deliverables for sponsors, including program reviews and technical reports.
  • Interact with sponsors, customers, partners, and data providers including universities, U.S. government agencies, national laboratories, foreign data providers, consortia, and international organizations (e.g. CTBTO).
  • Travel to assist with experiment execution, data collection, to interact with collaborators, sponsors and research customers and to present results at scientific meetings.
  • Perform other duties as assigned.


  • PhD in seismology, geophysics, or associated field.
  • Creativity, ability, and knowledge in quantitative seismology.
  • Experience in collecting, processing, and analyzing local/regional seismic data, including forward or inverse modeling.
  • Proficiency in organizing and analyzing large databases of waveforms, events, amplitudes, and arrivals for performing quantitative analyses.
  • Familiarity with seismological and geophysical methods for characterizing the subsurface.
  • Experience with programming skills (e.g. Java, C/C++, and/or Python), and experience with heterogeneous computing environments (Mac or PC, UNIX or LINUX platforms).
  • Ability to interact effectively with a team of interdisciplinary scientists having different backgrounds.
  • Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present, explain and publish technical information.
  • Ability to travel as needed


Desired Qualifications

  • Research experience in technologies for monitoring explosions or earthquakes or other seismic sources.
  • Experience in deploying geophysics sensors and systems in the field, and processing the data collected, or analyzing geophysical field data.
  • Experience in utilizing fiber optic (DAS) and/or other borehole sensor data.
