The quick and simple lowdown…

· My research is focused on earth surface processes, especially processes related to the cryosphere. · I have concentrated on mountain glacier flow dynamics, glacier hydrology, and snow processes in mountains and ice sheets. · My approach tends to combine detailed field research with computer data analysis and modeling. · My field studies are typically instrumentation/measurement oriented.

A few topics I work on (see publications for details)….

A few places I work

- Deformation of glacier ice - Glacier sliding - Subglacial hydrology - Snow densification processes - High elevation snowfall - Glacier-climate interactions - Crevassing - Snow hydrology

- Alaska (Chugach Mountains,Wrangell Mountains and Alaska Range) - Greenland Ice Sheet - Rocky Mountains - North Cascades, WA - Himalayas, Nepal
