Job Description

We have an opening for a Postdoctoral Researcher to utilize mass spectrometry for the characterization of complex mixtures of natural organic compounds from wetland field sites. You will advance our understanding of organic matter cycling by developing GC-MS, LC-MS, and other techniques to characterize the composition natural organic matter and other complex mixtures of organic compounds. This will be achieved through various extractions using columns and dialysis along with derivatization of compounds that traditionally escape GC and LC-MS detection. This position is in the Environmental Isotope Systems group of the Nuclear and Chemical Sciences Division.

You will



  • Collect and analyze wetland field samples.
  • Develop novel extraction and derivatization techniques for the characterization of organic compounds.
  • Build a GC-MS and LC-MS capability for the targeted and un-targeted analysis of organic compounds and natural organic matter.
  • Collaborate closely with several external research partners in the areas of organic chemistry, microbiology, geochemistry, hydrology, and earth system modeling.
  • Design and conduct research, pioneer experimental methodologies, interpret complex data, and be responsible for presenting results.
  • Communicate effectively (verbally and written) in a multidisciplinary team environment.
  • Author technical and scientific reports and publications and deliver scientific presentations.
  • Perform other duties as assigned.







  • PhD in Chemistry, Biochemistry, Geochemistry or related field.
  • Willing to do field work in wetland environments.
  • Experience with operating GC-MS and/or LC-MS instrumentation.
  • Experience in data mining and analysis of ‘omics data types (metabolomics, lipidomics, proteomics, etc.); applied mass spectrometry and/or other advanced analytical chemistry skillsets (e.g., NMR); or
  • Biochemistry or analytical chemistry sample preparation, such as solid phase extraction, chromatography, etc.
  • Proficient interpersonal skills necessary to interact professionally and productively with a diverse set of scientists, engineers, and other technical and administrative staff.
  • Ability to develop independent research projects.
  • Proficient verbal and written communication skills evidenced by published works and presentations.
