Research and Academic Interests:

GEOMORPHOLOGY: My research broadly covers hillslopes, fluvial systems and the linkages between them. I am also strongly interested in how climate influences geomorphic processes over historic, Holocene, and Quaternary timescales, and interactions between geomorphic and ecological systems.

Research questions my students and I address include:

  • How effective are forest fires in promoting geomorphic change in mountain landscapes, and what relationships exist between fire, climate and erosion over Holocene timescales?
  • How do climatic and tectonic factors and human activity control fluvial systems? What can fluvial terraces tell us about past and present environmental change?
  • How do tributaries influence process and form in mainstem streams, and what controls sediment storage and connectivity in hillslope, alluvial fan, and fluvial systems?
  • What are the effects of beaver activity on fluvial systems, and how do fluvial processes control beaver habitation and damming effects?
  • How do hillslope weathering and erosional processes control slope form in arid and semi-arid landscapes?
  • What are the impacts of large to extreme floods on fluvial systems, and what determines the geomorphic effectiveness of floods?
  • How do floods influence the transport and distribution of contaminated sediments (e.g. mine tailings) in fluvial systems?

I also have interests in late Pleistocene mountain glaciation and equilibrium line altitudes in New Mexico and the western USA.
