My research focuses on geophysical deformation of the shallow earth. I use a suite of satellite and terrestrial remote sensing platforms to characterize surface variations to gain a better understanding of the underlying geophysical processes that drive these changes. Recent projects include the impact of a granular proglacial ice mélange on tidewater glacier calving, the influence of perennial firn aquifers on tidewater glacier dynamics, and the relationship between cascading natural hazards (drought, wildfire, precipitation events, landslides) and climate change.
