I work with students studying disturbance impacts on the hydrology, geomorphology and riparian vegetation of streams, and on methods for documenting and modeling those impacts. Much of this work and that of my students has been in the Yellowstone ecosystem and in mountain environments.

I supervise student work in the following general research areas:

• Disturbance impacts on stream habitats
• Hydraulic, geomorphic, and sediment transport processes in streams
• Remote sensing, mapping and modeling of streams and riparian vegetation
• Fate and effects of mining sediments in stream systems
• Environmental education
