Research Interests

My research focuses on glacier erosion, basal till deformation beneath ice sheets, and the Quaternary history of Wisconsin. Current research projects include field stud- ies of fabric development of drumlins in Wisconsin and Iceland, bedrock erosion in Canada and Switzerland, and Quaternary mapping in Wisconsin. Complimentary laboratory studies include using a ring-shear device to examine the particle and magnetic fabrics of sheared basal till.

In addition, I have a burgeoning interest in the initiation of landslides and ground water flow across clay-rich aquitards in east-central Wisconsin as a result of mapping glacial sediments associated with pro-glacial Lake Oshkosh.
