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 extrace
