I’m a quantitative stream fish ecologist. I study the mechanisms by which fish behavioral and physiological responses to environmental conditions, such as stream hydrology and temperature, produce patterns in their distribution and abundance.

I spent ten years researching salmonids in Alaska, beginning with graduate research on juvenile Chinook Salmon behavior and population dynamics (including development of the VidSync software for 3-D analysis of fish behavior). My postdoctoral research was the Drift Model Project, a 3-year effort to develop and test better models mathematical of drift feeding, which is the primary feeding method of many stream fishes. In 2017, I moved to the Seattle area to work as a Senior Fisheries Ecologist for South Fork Research, studying steelhead in the Columbia River basin and continuing to study salmon in Alaska.

I am also a minor internet entrepreneur, photographer, and die-hard fly fisherman. I created Troutnut.com in 2003 to bring fly anglers’ accumulated knowledge of aquatic entomology online and get more people interested in the scientific aspects of the fly fishing and related sciences.
