My research and teaching interests are broad. I am an ecologist interested in the interactions between humans and natural ecosystems. While my area or expertise is vegetation change, I am always interested in taking on new student led projects. My research focus is in northern Alaska examining the influence of climate change and land use change on tundra ecosystems. I am also interested in Michigan vegetation especially in wetlands.
My research in Alaska is funded by the National Science Foundation. This long-term project uses small chambers to experimentally warm plots of vegetation in an attempt to simulate future climate change. We monitor the response of the plant species and important ecosystem parameters. The research takes place in Utqiagvik (formerly Barrow) and Atqasuk, Alaska. This work is in close collaboration with the International Tundra Experiment (ITEX); currently I serve as co-chair of the network. The results from this work are being used to better forecast vegetation change in the Arctic.
While not part of my research, I am also active in faculty governance and I serve as chair of the Faculty Salary and Budget Committee (FSBC).
