PhD 1982 University of British Columbia.
Faculty member in various capacities at University of Washington since 1985.
glaciology, climate change, ice sheet geophysics, firn physics
-I use ice-core data (e.g. depth-age) and geophysical data (e.g. ice-penetrating radar sections, ice-motion measurements, and borehole-temperature measurements) together with models of ice-sheet flow and temperature evolution, to infer properties of past climate such as accumulation rate, and temperature.
- I also work with polar-firn measurements and compaction models, with the goal of creating and calibrating a new transient model based more closely on the physics of microstructural processes and properties.
