My research interests lie in understanding the dynamic interactions between water, sediment, vegetation, and anthropogenic processes responsible for the formation and evolution of physical landscapes. I primarily focus on the morphodynamics of channelized flows, with a heavy emphasis on process-based field investigations of sediment flux through fluvial systems and river hydrodynamics. An important aspect of my research is rooted in examining how the interactions between process and form are linked across spatial and temporal scales. Ultimately, the goals of my research are to apply the knowledge gained by studying present day geomorphic systems to enhance interpretive geologic models of past environments and improve predictive models of future landscape evolution.
