Profile
I am thrilled to re-join the Northland College community as an Assistant Professor of Natural Resources and Biology starting Fall 2011. It is exciting to be able to teach field botany and ecology courses at a small liberal arts college that places a strong emphasis on natural history knowledge and application. While I enjoy Northland’s small campus, I enjoy even more the seemingly endless number of classrooms within the surrounding landscape. I am eager to spend time with students in hardwood swamps, pine barrens, bogs, mesic forests, sedge meadows, beaches, and other Northwoods gems.
My research interests largely focus on long-term dynamics and patterns of diversity and composition in plant communities of the Great Lakes region. To interpret these patterns, I consider the roles of multiple interacting drivers of ecosystem changes at local and landscape scales including succession, habitat fragmentation, herbivory, pest invasions, changes in natural disturbance regimes, and climate change. To provide a richer baseline for tracking future changes in Great Lakes ecosystems, I have worked closely with the Great Lakes Inventory and Monitoring Network and colleagues from the University of Wisconsin-Madison to assist in the development of protocols for monitoring terrestrial vegetation in nine National Parks throughout the Great Lakes region. I look forward to working with Northland students and faculty to pursue other meaningful collaborations on projects with the extensive network of natural resource agencies and organizations in the region.
