My research interests include landforms on the Earth's surface that are sculpted by flowing water in the form of rivers and glaciers and by wind and windborne particles. My work seeks to understand the intrinsic feedbacks between landforms on the Earth's surface and the fluid flow above the surface which creates these self-organized patterns. I focus on computer modeling and on the integration of model results with field and remote-sensing data.
