Aquatic ecology, trophic interactions in lakes and streams.
Ph.D., North Carolina State University
My current research interests concern the ecology of rural and urban NC Piedmont streams, including effects of stream restoration on ecological processes, methane cycling and use of methane-derived carbon in stream food webs, fate of anthropogenic nitrogen in streams, and fate of coal ash contaminants in the Dan River food web.
