I'm a geoscientist with a long-standing interest in how rivers and glaciers have shaped our landscape. In recent years, I've also become interested in how humans have influenced the processes of landscape change and how our management of natural resources can be informed by a better understanding of our influence on these processes. Prior to joining NREM and the Environmental Science interdepartmental graduate program, I held teaching positions at various schools including ISU, Lafayette College (PA), St. Olaf College (MN), Metropolitan State University (MN), and Grinnell College (IA).
My research deals broadly with physical processes that shape earth's surface and the impact of environmental and human-induced changes on these processes. Most of this work involves the interactions between fluids and soil/sediment in glacial, fluvial, and hillslope settings. My research group combines field work, GIS analysis and numerical modeling to address problems ranging from the grain scale to the landscape scale, and employing concepts and methods from fields as diverse as ecology and materials science. The ultimate goal of our work is to better understand the geomorphological context within which our environmental management decisions take place and to use that understanding to guide better management.
My group's research aims to provide a basis for understanding relationships between cause and effect in earth surface physical systems. As such, some of our output can be applied toward monitoring system changes that could influence management strategies. For example, some of our current work addresses spatial and temporal changes in midwestern stream channels, and their implications for watershed budgets of sediment and contaminants. Some channel changes represent a lagged response to climatic or geological changes in the distant past or land use changes in the recent past, while others may be triggered by local influences within channels or on the channel boundaries. Understanding the causes and response dynamics is essential for wise and effective management, mitigation, and restoration of stream form and function.
