As a research hydrologist with the GCMRC and SBSC, I conduct original research linking hydrology and sediment transport to fluvial geomorphic processes.  My research is conducted in the Rio Grande in the Big Bend region of far west Texas, the Green and Yampa Rivers in Dinosaur National Monument, the Green and Colorado Rivers in Canyonlands National Park, the Little Colorado River and its tributaries in northern Arizona, and the Colorado River in Grand Canyon National Park. My research aims to quantify how hydrologic and geomorphic processes respond to factors such as climate change, large-scale water development and management, the widespread establishment of non-native riparian plants, and anthropogenic modifications to fluvial bottomlands. All of these perturbations directly affect how water and sediment are routed through fluvial drainage networks, which controls the geomorphic behavior, and biologic processes of these river systems.
