   abstract: '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.Much
     of my work incorporates the use of acoustic instrumentation to passively monitor
     suspended-sediment transport processes on rivers with high suspended-sediment
     loads.  This work is paired with measurements of geomorphic change using a variety
     of data and techniques including: high-resolution topographic data collected
     with real-time-kinematic GPS and LIDAR, aerial imagery, and analysis of historical
     hydrologic and geomorphic data. My work is directly relevant to the primary
     scientific understanding of the hydrologic and geomorphic behavior of these
     rivers, as well as the management actions that may help mitigate fluvial perturbations
     that have occurred.  My work also focuses on the biogeomorphic interactions
     between stream flow, sediment transport, and riparian vegetation, and how those
     interactions can result in negative and/or positive feedbacks of geomorphic
     change.'
