I am a community ecologist whose general area of research concerns the ecology of benthic algae and invertebrates in streams and lakes. Since 1995, most of my research has been examining the long-term recovery of streams in the Slippery Rock Creek watershed following passive treatment of acid mine drainage. Other recent research has focused on the effects of mine drainage on stream productivity, and the use of benthic algae as indicators of eutrophication in Irish lakes. Over 30 undergraduate students have done research in my lab on these projects. Ultimately, my long-term goal is to construct a model that can predict the development of benthic algal communities in streams for a variety of conditions.
