I am a physical scientist who is interested in the interactions and feedbacks between the hydrologic, geomorphic, and ecological processes that occur along riparian corridors. I work at various scales to understand how fluvial processes influence the recruitment and success of different riparian species and how the distribution and structure of the vegetation community alters fluvial processes and, as a result, the size and shape of the river channel. My research is motivated by the need to predict changes in the physical template of our river systems in response to a changing climate, increasing pressure to develop limited water resources, and the pervasive threat of invasive plants, as well as the growing appreciation of the fundamental role of plants on geomorphic processes.
