Research Interests:
Landforms on Earth's surface are sculpted by flowing water in the form of rivers and glaciers and by the wind and windborne particles. My work seeks to understand the intrinsic feedbacks between landforms on Earth's surface and the fluid flow above the surface which creates these self-organized patterns. I focus on computer modeling and in the integration of model results with field and remote-sensing data.
Active research projects:
- Dust emission and
deposition from playas
- Spiral troughs on Mars
- Formation of
oriented thaw lakes
- Quaternary
landscape evolution in Cuyama Valley, CA (led by S. DeLong)
- Oscillations in
arid alluvial channels
- Drainage basin evolution
- Experiments in the Rainfall Erosion Facility
- Quaternary
evolution of alluvial fans in the Southwest U.S.
- Quaternary
dating of terraces with scarp evolution
- Flexural modeling in response to glacial erosion
in the western U.S.
- Coherence
resonance and ice ages
- Controls on soils formation and modern
calibration for paleoclimates
