My research is devoted primarily to understanding glaciers and the spectacular imprint they leave on the landscape. Glacier dynamics and landscape modification are particularly sensitive to processes at glacier beds, which is the focus of much of my effort. This research involves field experiments at modern glaciers, field measurements in formerly glaciated landscapes, laboratory experiments, and the formulation of models aimed at characterizing glacial processes.

Current and proposed projects include the following:

Field and modeling studies of drumlin formation in Iceland
Field studies of flute and crevasse-fill ridge formation in Iceland
Use of magnetic till fabrics to infer deformation kinematics of soft beds and related landform genesis, with laboratory experiments to calibrate fabrics to strain characteristics
Field studies of strain in glaciotectonically thrusted and folded sediments in Denmark
Laboratory studies of glacier sliding, erosion, and sediment transport with a custom device that rotates a ring of ice (0.9 m O.D.) at the pressure-melting temperature over a rigid or deformable bed
Laboratory studies of the rheology of temperate ice as a function of its water content
Modeling of bedrock erosion by glaciers
LiDAR-based studies of glacial landforms

This research is funded primarily by the National Science Foundation, through grants awarded by Earth Sciences and Polar Programs. Most of these projects include student research opportunities. Enquiries from prospective students are very welcome.
