My research is of particular interest to state, federal, and non-governmental agencies including Tribal Nations because I focus on identifying relations and mechanisms related to rare, declining, or economically important aquatic species for which the causes and corresponding management responses are unclear. As a researcher, I am broadly interested in the conservation and management of lotic ecosystems, but I conduct research in three primary areas – 1) disturbance of stream ecosystems (e.g., environmental flows, drought) 2) improving riverine sampling, and 3) ecology, conservation, and management of stream fauna.
