Fluvial geomorphology, hydrology, late Quaternary environmental change, alluvial stratigraphy, floodplain pedogenesis, geoarchaeology, and human modifications of river systems. My work investigates the development and behavior of geomorphic systems over timescales ranging from decades to several millennia. Recent and on-going projects include: flood hydrology of the North Platte River, Wyoming and Colorado; channel response to forest mortality from beetle infestation in Fraser Experimental Forest, Colorado; paleoenvironmental reconstruction and geoarchaeological reconnaissance of coastal Estremadura, Portugal; late Holocene fluvial responses to environmental change in the Great Plains.
