Research Interests

My primary research interest is in understanding how climate change, disturbance, and biophysical interactions across spatial and temporal scales affect population dynamics of aquatic organisms and their habitats in mountain streams.

Climate- Aquatics Blog: This website archives blogs periodically written by the scientist that describe research pertaining to climate change effects on aquatic resources.

Stream Temperature Modeling and Monitoring Website: This website acts as central repository for information pertaining to monitoring and modeling of stream temperatures that the scientist and his collaborators develop.

SSN & STARS: Tools for Spatial Statistical Modeling on Stream Networks: This website hosts freeware statistical software and GIS tools for implementing a new class of spatial statistical models applicable to data measured on stream networks.

NorWest Stream Temperature- Regional Database and Model: This website hosts a comprehensive interagency stream temperature database and high resolution climate scenarios for the Northwest U.S.

Why This Research is Important

Many natural resources are at risk from human development of natural landscapes and the effects of climate change. My research attempts to provide better understanding and predictive models of stream ecosystems so that managers can respond proactively and more effectively to these threats.
