Research Interests
My research interests fall into the general category of aquatic ecology. More specifically, my research group has examined the role of limiting nutrients in the structure and functioning of stream ecosystems and has characterized the effects of storms on water chemistry in streams. Of late, our most recent efforts have been focused on a variety of aspects of the ecology of streams receiving acid mine drainage, e.g., the effects of AMD on stream productivity and community structure and the bioaccumulation of heavy metals by stream biota exposed to AMD.
