My study interests encompass surface processes, geomorphology, sedimentology and stratigraphy. More specifically, I am interested in studying the landforms sculpted by Pleistocene megafloods around the world; the associated terrestrial backwater sediments and marine turbidites; and the global distribution patterns of the sedimentation. Investigative tools used include GIS for mapping, gamma-ray profiles for stratigraphic proxies, and field data utilizing GPR/seismic methods.

My main project is on the Quaternary landform evolution of the Grand Valley and Grand Mesa system of the upper Colorado River Basin in western Colorado. Debris flows, glacial flood deposits, and terraces are investigated using methods such as optically stimulated luminescence (OSL) for dating (worked at Utah State University Luminescence Lab, summer 2018) and electrical resistivity tomography (ERT) for subsurface scanning.
