Postdoc in Soil Organic Matter-Mineral-Microbe Chemistry

LLNL seeks a postdoc to address the role of microbial physiology and mineralogy in soil C cycling.

The Physical and Life Sciences Directorate at LLNL is seeking a postdoctoral researcher to apply isotope tracing and biogeochemical analyses to a multidisciplinary study of microbe-mineral interactions and soil organic matter stability. This research will examine the relationship between microbial traits, organic matter characteristics, and stability of organic matter at mineral-water interfaces, in soil microcosms, and at the field scale. The appointment will support LLNL’s multi-investigator program in soil microbiome C cycle research. The postdoc will be part of the LLNL Isotope Biogeochemistry Group and report to Dr. Jennifer Pett-Ridge and Dr. Mavrik Zavarin. The research will take advantage of LLNL’s many analytical tools which include a Cameca NanoSIMS 50 ion microprobe, LLNL’s NMR facility, TEM, and accelerator mass spectrometry. The research also includes active collaborations with external organizations such as UC Berkeley, LBNL-Advanced Light Source, and the Environmental and Molecular Sciences Laboratory (EMSL).

We seek applicants with training in biogeochemistry, soil chemistry and microbial ecology to pursue this innovative research using advanced spectroscopic techniques, stable isotope probing, 14C analysis, and imaging techniques to probe the characteristics of organic matter-mineral interactions. This person will contribute to an interdisciplinary team deploying greenhouse microcosm and field experiments that interrogate biogeochemical factors affecting soil carbon stability.
