Statement of Research:
My research focuses on understanding the effects of climate change, contemporary forest harvest and disturbances on fish and both riparian and aquatic habitats, and more generally on the ecological linkages among water, land, and people. My goals are to use multiple lines of inquiry from various approaches to understand the complexities of fish and the aquatic and riparian world with implications for management and policy planning. In 2021, I was appointed to be the HJ Andrews Experimental Forest Lead Scientist, in addition to my duties as a Research Fish Biologist.
