My research focus is in using quantitative methods to precisely understand how soils function and change— spatially, and through time. Such methods are far from developed but I believe some combination of mechanistic and statistical modelling is required to do this. I research methods for comprehensive digital soil mapping aiming to characterize soil both in the lateral and vertical dimensions. Additionally, I contribute methodology for quantifying (and validating) measures of uncertainty for these comprehensive soil information systems. Outputs of this sort of work are intended for feeding into environmental modeling and monitoring programs, where precise land management decision making is required at all manner of spatial scales.
