Debris flows, Landslides, Geomechanics

Image of Current Focus for Debris flows, Landslides, Geomechanics

My research focuses on the mechanics of geological processes, particularly debris flows and landslides, but also volcanic extrusions and related phenomena.  This research includes a theoretical component (development of new mathematical models), an experimental component (e.g., work at the USGS debris-flow flume, pictured above with the flume crew in May, 2008), a field component (mostly at Cascades Range volcanoes), and a practical component that emphasizes hazard assessment.
