We are seeking a Postdoctoral Researcher to investigate soil carbon persistence, organic matter pools and changes in microbe-mineral-organic interactions with depth in agricultural soils. You will support a multi-disciplinary team studying carbon dioxide removal, sustainability and microbe-mineral interactions in bioenergy cropping systems. This position is in the Environmental Isotope Systems Group of the Nuclear and Chemical Sciences Division.

You will:

• Use soil radiocarbon data to determine the age and turnover (mean residence time) of soil organic carbon under different crop treatments.
• Characterize soil organic matter using soil density fractionation, NMR and/or FTIR.
• Develop optimal techniques for characterizing extracellular polymeric substances (EPS) from soil samples.
• Perform independent research and lead new lab incubation or isotope tracing studies to characterize soil organic carbon stability.
• Assist with the collection of soil samples from bioenergy farm sites in the US.
• Collaborate with other scientists and technical personnel to accomplish research goals.
• Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings.
• Perform other duties as assigned.
