My research utilizes remote sensing, field work, numerical modeling, and physical experiments to better understand (1) the morphodynamics of fluvial, deltaic, and coastal systems; and (2) interactions between vegetation, climate, and surface processes.

Current research efforts:

  • Modeling the influence of ice and permafrost on delta morphodynamics
  • Quantifying Arctic delta morphologic variability
  • Permafrost effects on channel migration
  • Improving representations of coastal landscapes and riverine fluxes in Earth system models
  • Controls on entrainment of sediment into sea ice
  • Beach erosion on a sea-cliff and wave-cut platform
  • Seasonal and tidal variability in island hydrodynamics
  • Effects of vegetation on delta morphodynamics
