Professor of Plant Biology
Office Location: 223 North Kedzie Hall
My research and teaching interests are broad. I am an ecologist. I am interested in what controls the variety, numbers and distribution of plants, animals and microorganisms. My early training was in classical phytosociology and plant taxonomy. For my doctoral work I applied factor analysis to vegetation studies and later my students and I were among the first to make multi-layered maps using Geographic Information Systems techniques. We pioneered a mapping method which has become a standard required by regulatory agencies in planning prior to resource development. I am perhaps best known as an Arctic ecologist but I also have experience in the landscape ecology of managed landscapes such as are prevalent in the Midwestern United States. Currently I am interested in many aspects of global change. Of particular concern is the need for global change research to branch out from being a climate change program to include issues of resource sustainability in a changing world. Global change research must include the "human dimensions of global change". I teach mostly undergraduate courses in ecology, plant science and environmental awareness. I have directed several large research projects, for example the San Juan Ecology Project, the US Alpine Program of the International Tundra Biome Programme, and I was the founding Principal Investigator of the Alpine Long-Term Ecological Research program of NSF. I have also been director of two large university research institutions. I have helped plan and direct many international science programs such as the International Biological Program, the Comité Arctique International Revegetation Program, the International Tundra Experiment (ITEX) of the Man and the Biosphere Programme of UNESCO and the NSF Arctic System Science Program. My goals at this point in my career are to be a good teacher and to facilitate others to do excellent research.
