My research focuses on ecosystem dynamics of rivers and streams. I am broadly interested in carbon, nitrogen, and phosphorus cycling in these environments, and how nutrients are affected by human activities (including restoration), and by linkages with other aquatic ecosystems. Much of my work is done at the interface between ecology, geomorphology, and hydrology.  For reprints of recent articles, pdf files are available from my publication list or they can be obtained from the Center for Limnology library at Center for Limnology library.
