Research interests

My research interests are in reconstructing the dynamics of past glaciers and ice sheets through the tools of glacial geomorphology and Quaternary geology. In particular, I study the deglaciation dynamics of the North American Ice Sheet Complex and the linkages to global climate during the Late Glacial. I use both remote sensing (mapping from satellite imagery and digital elevation models) and field-based methods. To support my studies with quantitative dating, I have been using cosmogenic exposure dating and optically stimulated luminescence. Geographically, my research focuses on North America, but I have also published studies from Europe, Siberia, and Antarctica.
