My research program involves the interaction of sedimentological and biological processes within the fields of paleopedology and ichnology. I combine these disciplines to study the evolution of modern and ancient soils, soil ecosystems, and landscapes as well as to demonstrate the broad environmental, climatic, and ecological applications of paleosols and ichnofossils, especially in evaluating the effect of long-term climate change on terrestrial ecosystems through Earth history. This involves not only the study of paleosols and continental trace fossils throughout geologic time, but also the experimental study of modern soils and the burrowing activities of extant terrestrial annelids, arthropods, amphibians, and reptiles.

My recent research projects have involved the study of the influence of climate change on ancient soils and soil ecosystems including those of the Pennsylvanian-Permian of southeast Ohio and West Virginia, as well as the Eocene to Pliocene of Colorado, Wyoming, southern Bolivia, and Ethiopia.
