Major Research Interests

• Surficial geology with a focus on paleopedology

Current Research Projects

• Paleosol morphology
• Loess-paleosol stratigraphy
• Geologic mapping and soil chemistry for stratigraphic correlations and environmental assessments
• High resolution studies of soil horizons and glacial stratigraphic units for distinguishing primary (original) and secondary (altered) states of the geologic materials
