Expertise

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 effects of sea level rise/inundation on coastal permafrost thaw subsidence
Understanding thermokarst lake morphologies and heat fluxes in permafrost landscapes
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
