I am interested in various surface processes occurring in rivers, deltas, estuaries and marshes. Recent efforts have focused on fluvio-deltaic and coastal plain systems, focusing on the hydrodynamic and geomorphic response of these systems to internal and external forcings at various time-scales, frequently spanning from inter-annual to century. We do so by studying regional-to-local processes driving geomorphic change using observations in the field, numerical process-based models, and often reduced complexity models. Much of my research takes place in the Mississippi River Delta Plain, where the ongoing transgression provides unique conditions to study the effects of sea level rise, storms, and other processes on wetlands, barrier islands, and the modern delta, with transferable knowledge to other systems around the world. Recent research efforts include paleo wave climate and tidal current reconstructions to better understand regressive systems and basin infilling, processes controlling the development of stratigraphy in tidal point bars, the morhodynamics of the fluvial-to-marine transition, morphodynamics of barrier islands, controls on delta distributary channel kinematics, and exchange processes between estuaries and the coastal ocean.
