Research Scientist, USFS
I currently work as a scientist for the US Forest Service in Missoula, Montana. I work primarily in the fields of landscape ecology, remote sensing and mountain climatology. Mountains create steep biophysical and climatic gradients that pose unique modeling challenges. My current research focuses on predicting climate to the scale of terrain and using those models to improve our understainding of disturbance and vegetation dynamics. I have a strong interest in developing models and tools that bridge the gap between research and management. I believe that by integrating research and management we can save taxpayer dollars while improving how we manage natural ecosystems.
Field Of Study:
Ecology, Climate, Climate Change, Remote Sensing, biogeography, fire ecology
My research interest span the disciplines of climatology, disturbance ecology micrometeorology, landscape ecology and remote sensing.
Ph.D., University of Idaho, 2008
I work for the USDA Forest Service in Missoula, MT. I am also a member of the faculty at the University of Montana and the University of Idaho.
