I am interested in studying the factors that influence fish distribution and persistence. I am curious about the effects of climate change on fish movement and habitat quality, and how the models we're currently developing will reflect what happens in the region's streams over the next few decades. I enjoy helping and supporting resource managers in their development of long-term temperature monitoring networks and stream temperature models.
Fish biology and behavior, as well as the study of habitat quality, are very complex issues. While many attributes have been studied in an attempt to define high-quality fish habitat, stream temperature may be one of the biggest factors influencing their survival.
