Research Interests

I am interested in using data to influence management decisions so that stream habitats are conserved in the face of climate change using the most cost-effective and biologically relevant approaches. I enjoy collaborating and coordinating with resource managers and scientists to create data and information sharing opportunities for the benefit of research and land management. I also find disturbance ecology fascinating, especially the short and long-term effects of wildfire on stream habitat and aquatic communities.

Past Research

Fish habitat inventory procedures and database development, wildfire and prescribed burn effects on large woody debris and other habitat characteristics, and implications of using various fuel reduction practices in riparian areas.


Why This Research is Important

In most aspects of fish and fish habitat research, we are not data poor, but rather, lacking in data organization and coordination. Given 1. There are huge quantities of historical data in addition to continuing data collection, 2. The massive expenditures associated with such data collection, and 3. The vital importance of long-term, and spatially explicit and extensive data sets, it only makes sense to tap these data to address time-sensitive conservation questions that require large long-term and reliable data sets.
