Current Research

Research Interests

Development of landscape scale spatial models that substantially impact aquatic biology, such as: debris flow prediction, valley morphology mapping, stream gradient estimates, and stream temperature modeling.

Past Research

Landscape-scale work involving: land cover and vegetation mapping from satellite imagery, wetland mapping, air inversion modeling.

Why This Research is Important

Debris flows may damage homes, structures, and roads in valleys, but also impact the biology of invasive and endangered species. Stream gradient and temperature have a major influence on the location and number of game fish, such as cutthroat trout.
