   personal_statement: '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.'
