Assistant Professor
I am a geoscientist who utilizes novel in situ geophysical and remote sensing tools to study earth surface processes, particularly related to the cryosphere. My research has involved more than 20 expeditions to Antarctica, Greenland, Alaska and Patagonia.

Professor
I am a fluvial geomorphologist with interests in drainage basin response and recovery to sediment disturbances including floods, fires and mass movements, the influences of climate change on channel morphology and vegetation-channel feedbacks, and process-based channel restoration and monitoring.

Malcolm McCallum Chair of Economic Geology
Associate Professor
I study economic geology building on a background in petrology, structural geology, field geology, inorganic and organic geochemistry. My current research projects examine fluid:ore interactions from magmas to environmental impacts.
