Really big landslides and hazards cascades

Massive rock avalanches are becoming increasingly 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

Satellite-derived glacial lake outlines, Nepal Himalaya

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.
