Job Description

We are seeking a Postdoctoral Research Staff Member to join a US Department of Energy-funded multi-institution research program led by LLNL ( focused on sustainable and predictable bioenergy crop production. This is a team-oriented project that uses a community systems biology approach to understand resource allocation consequences of microscale symbioses between microbes and bioenergy-relevant crops. Your role will be to learn to use a unique next generation imaging mass spectrometry instrument (NanoSIMS) with a cryogenic stage and ultra-high spatial resolution to elucidate biogeochemical processes relevant to US Department of Energy research priorities for bioenergy and carbon cycling. You will have the opportunity to design and execute experiments and publish the results, as well as develop new research directions.


In this role you will:

  • Develop and pursue innovative research related to sustainable bioenergy, carbon cycling, microbial ecology, and/or host-microbe interactions.
  • Develop expertise in high spatial resolution secondary ion mass spectrometry (NanoSIMS), including instrument tuning, troubleshooting and data collection.
  • Develop cryogenic and room-temperature sample preparation methods for NanoSIMS and other imaging techniques.
  • Collaborate with a diverse team of multidisciplinary scientists and technical personnel.
  • Analyze and interpret NanoSIMS and other data.
  • Present research findings at seminars, technical meetings, and scientific conferences
  • Publish research results in peer-reviewed scientific journals.
  • Perform other duties as assigned.

  • Demonstrated ability to design, execute and interpret experiments.
  • Knowledge of microbial and biogeochemical processes.
  • Experience operating and troubleshooting scientific instrumentation.
  • Knowledge of data evaluation for quality and statistical analysis.
  • Ability to work independently, develop testable hypotheses, and interpret the implications of results.
  • writing and verbal communication skills, including peer-reviewed scientific articles and scientific conference presentations.
  • Ability to work in a multi-disciplinary team.

Qualifications we desire

  • Experience with mass spectrometry, including secondary ion mass spectrometry (SIMS) and stable isotope tracing.
  • Experience with biological imaging, including room temperature and cryogenic sample preparation methods.
  • Experience researching microbial and/or biogeochemical processes in soil and/or plants .
  • Knowledge of US Department of Energy Office of Biological and Environmental Research programs, including bioenergy and the terrestrial carbon cycle.
