Research

My research focuses on the quantification and interpretation of soil morphology. At the pedon/polypedon scale, we are employing electromagnetic induction techniques (electrical conductivity and magnetic susceptibility), and associated inversion modelling to characterize soil hydromorphism, as an indicator of soil drainage conditions. At the sub-pedon scale, we are employing high-resolution optical digital imaging of soil thin sections, as well as x-ray computed tomography (CT) of intact soil cores, combined with pixel- and context-based image processing, to quantify the spatial configuration of soil components. Our micromorphology research draws upon the Canadian Soil Thin Section Collection, curated in our laboratory. We have on-going collaborations with researchers in Canada, the United States, South America and Europe.
