Really big landslides and hazards cascades
Massive rock avalanches are becomingÌýincreasingly frequent due to glacier debuttressing of oversteppened valley walls, and thaw of alpine permafrost. In other words, they are becoming more common as a result of climate change. Sometimes these can trigger a domino effect of secondary or tertiary geohazards, such as damming a river, which impounds a hazardous lake, or triggering a tsunami.

Glacial lake evolution
We are working to understand how glacier lakes are evolving in space and time. These often ephemeral lakes present acute hazards to populations and infrastructure downstream.

Quaternary environmental change
The landscapes of western North America have undergone substantial change over the late Quaternary, including marked variations to relative sea levels, glacier extent, etc. We use a combination of field mapping, remote sensing, and archival research to unravel the landscape changes over the past ~20,000 years.

Other research
I have conducted research on a variety of other topics, including process fluvial and aeolian sediment transport, ground ice in permafrost, and medicine cabinet contents.
