Quaternary stratigraphy: Litho-, chrono-, pedo-, bio-, and magnetostratigraphy of eolian deposits (loess and sand) in the central Great Plains, and environmental (flora, fauna, climate) reconstruction.
Stable isotope geochemistry: Application of stable isotopes (δ13C, δ15N, δ18O) to soil-vegetation-climate relationships in modern soils and paleosols of the central Great Plains.
Geoarchaeology: Paleoenvironmental conditions and landscape evolution in the central Great Plains, as related to prehistoric peoples; modeling the distribution of surface and buried cultural materials.
Fluvial geomorphology: Stream system response to late-Quaternary (middle-late Pleistocene and Holocene) climatic variation, and development of alluvial chronostratigraphies.
Geologic mapping of Neogene and Quaternary deposits : Field mapping and development of large-scale digital maps of surface and near-surface geology for selected areas of central and western Kansas. http://www.kgs.ku.edu/General/Geology/index.html
