My general research interest is on the quantification of soil morphology at several scales of observation. At the local catchment scale we are employing high-resolution airborne remote sensing techniques: a) visible/near-infrared imaging of soil and crops are used to reveal variations in soil type, b computerized photogrammetry of stereo-airphotos and Lidar imaging are used to generate digital elevation models, from which landform quantification is performed. At the pedon/polypedon scale, we are employing thermal imaging and non-contacting magnetic induction techniques (electrical conductivity and magnetic susceptibility) to generate, through inversion modeling, 3D soil models. At the sub-pedon scale, we are employing high-resolution digital imaging of soil thin sections, as well as X-ray micro-computed tomography (mCT), combined with pixel- and context-based image processing, to reveal the spatial configuration of soil components. We have on-going collaborations with researchers in Canada, the United States, South America, Europe and Africa.
