  • Ph D Kansas State University 2019


I grew up in a small town in south-central Kansas, and cut my teeth on sandbed rivers in the Arkansas River Basin. I completed a masters and PhD at Kansas State University, where I researched fish passage solutions for Great Plains fish communities and movement and early life history ecology of desert suckers. My research interests are centered around the conservation and ecology of freshwater fishes, and my research experiences have taken place across a diverse array of aquatic systems, including small streams, large rivers, and reservoirs in the Great Plains and desert southwest. I first joined the Budy Fish Ecology Lab in April 2020 as a postdoctoral research fellow assessing climate change impacts on Alaskan arctic lakes and continuing to research desert fish ecology. I am currently research faculty in the Department of Watershed Sciences at Utah State University.. Aquatic ecology and conservation, population and community ecology, animal movement
