Research Interests

Landscape evolution, tectonic geomorphology, impacts of climate change on hillslope and fluvial systems, numerical simulation of landform development.

Current Research Projects

• Geomorphology, hydrology, and Quaternary chronology of Colorado arroyo systems, their role in long-term landscape evolution, and implications for sensitivity to climate change.

• Analysis and field testing of long-term stream erosion laws.

• Response of mountain drainage basins to differential normal-fault movement, Italian Apennines.

• Geomorphic and stratigraphic evolution of lowland meandering-river valleys.
