Research Interests

• Configuration, dynamics, and geological constraints of the North American continental ice sheet
• Environmental geochemistry
• Glacial sedimentology and stratigraphy
• Neotectonic methods for detecting prehistoric seismic events, particularly in lakes
• High Arctic glacier sedimentation
• Sedimentation and genesis of eskers
• Arctic and temperate limnology, especially geophysical methods of studying physical limnology, subbottom and sidescan acoustic profiles, and geochemical profiles of cores as indicators of the relative importance of anthropogenic and natural sources of elements
• Stratigraphy and glacial sedimentation of the Hudson Bay Lowlands and Québec Appalachians
• Drift mineralogy chemistry for correlation, drift genesis, and applied studies
• Terrestrial and sublacustrine periglacial features, notably the patterned ground of Canadian Shield
• Mineral prospecting in glaciated terrain
