My research focuses on earth-surface processes (geomorphology) applied to a broad range of problems. Much recent work involves rivers, fluvial geomorphology, flood hydrology, floodplains and watersheds. My research group applies fluvial geomorphology, hydrologic and statistical tools, hydraulic modeling, and other approaches to assess river dynamics and flood hazards. Although much current research focuses on rivers, I continue to work on a broad range of processes that shape the earth surface and operate, in particular, over anthropogenic time scales (yes, the "Anthropocene"). One pressing human application is for managing risk from natural hazards, and my group has worked extensively on quantifying those risks, guiding mitigation and other solutions, and providing a scientific basis for sound natural-hazards public policy.
