Academic Appointments

The Frank J. Reagan '09 Chair of Policy Studies
Professor of Geography
Adjunct Professor of Earth Sciences

My teaching and research interests focus primarily on fluvial geomorphology and surface water hydrology. In particular, my research addresses stream channel and watershed response to environmental change – whether the change is generated by natural (e.g. climate change) or anthropogenic (e.g. agriculture, grazing, or logging) causes. For example, I have worked on the geomorphic impacts of catastrophic floods in the Upper Mississippi River as well as glacial outburst floods in Iceland. At a more local level, I have been analyzing the geomorphic impacts of Hurricane Irene that ravaged eastern Vermont in late summer 2011. Currently, I am focusing on the links between channel processes and riparian ecology, especially the role of flow regulation by dams on aquatic and floodplain ecology. This work was recently highlighted in a National Science Foundation online newsletter and PBS.

Besides this current research on the hydro-ecological impacts of dams and dam removal, I also have a project in the Peruvian Atacama Desert investigating the long-term evolution of El Niño floods and the regional relationship between climate change and cultural history. Students are actively involved in all aspects of my research and are an integral part of all my research activities.
