Research Interests

My past research has focused on aquatic primary production, distribution and diversity of aquatic macroinvertebrates, ecohydrology, and the ecology of rivers and flood plains. Broad interests include riverine landscape ecology and dynamics, aquatic invertebrate and algal ecology, aquatic food web structure and dynamics, habitat conservation, and land-water interactions. Research experiences in Michigan, New Hampshire, Alaska, Minnesota, New York, Italy, Switzerland, New Zealand, and Antarctica have provided me with a broad spectrum of experiences in aquatic habitats from the arctic tundra to the European and Southern Alps to Antarctica.
