Pedogenesis; Anthropedogenesis; Subsoil Processes; Soil Heterogeneity
Specific research areas include the contemporary environmental implications of subsoil morphology in Spodosols and Ultisols; drivers and implications of inter- and intra-horizon variability of the subsoil C cycle; geochemical and geophysical signatures of weathering; and utilization of soil taxonomy to predict soil physical properties at regional scales.
