I'm associated with the geography/GIScience faculty and the geology and soils faculty. J., 2008, Loess record of the last Glacial-Interglacial transition on the northern and central Great Plains, Quaternary Science Reviews 27, 1772-1783. For much of this work, I use optical dating techniques (aka "Optically Stimulated Luminescence," a relatively new dating technique that is used for recently deposited geological materials) to construct chronologies of river, dune, and hillslope sediments. The optical age was determined from a sample from 1.0m depth using the Single Aliquot Regenerative Dose (SAR) technique.
My main research interests are studying the responses of river, hillslope, and eolian (wind-deposited) systems to climate change.
My research goals include studying the evolution of the Platte River system, the responses of rivers and dune systems to climate change in the recent past, and the causes for stream incision on the western Great Plains and the central Rocky Mountains.
