I am interested in landscape dynamics, generally focused on understanding and predicting changes in the patterns and functions of landscapes in response to anthropogenic effects. The objectives of my research are to gain an understanding of the processes that control landscape form and function as well and key interactions between hydrology, sediment transport, climate, vegetation, and human impacts in a variety of settings. Examination of these processes and interactions in different environments can ultimately lead to a more general and regional perspective of landscape morphodynamics and evolution. The recent research that I have initiated at USGS is a reflection of my direction and interests. I am keenly interested in sediment transport and particle residence times in varying fluvial and estuarine environments and how these change in response to human activities (such as best management practices (BMPs), dam management, and restoration activities). I am also interested in the behavior and transport of particle-associated contaminants and nutrients as a result of industrial activities, energy extraction, and agricultural and land use practices.
