Y research addresses the ecology and conservation of aquatic and riparian ecosystems. I employ a highly interdisciplinary approach, drawing from stream ecology, fluvial geomorphology, trophic ecology, and landscape ecology to holistically address basic ecological questions as well as applications to conservation and management. Unified by the theme of ecosystem-scale dynamics, my principal research activities focus on linkages between stream geomorphology and ecology, ecological connections between aquatic and terrestrial ecosystems, and watershed landscape ecology.
