Hometown: Salmon, Idaho

Ryan completed his M.S. degree working with Dr. Colden Baxter in the ISU Stream Ecology Center in spring 2013 and is presently a biologist with the Shoshone-Bannock Tribes. Ryan has a Bachelor of Science degree in Biology from the University of Idaho. Before coming to ISU, he completed a summer internship with Jim and Holly Akenson at Taylor Wilderness Field Station within the Frank Church ‘River of No Return’ Wilderness and worked for the National Park Service in Grand Teton National Park, WY on a wolf-predation survey. He has also been a river guide on the Middle Fork of the Salmon River. His M.S. research (conducted out of the Taylor Wilderness Field Station) focused on the ecology of streams in winter and the role of ice in stream ecosystems. Ryan also investigated unique linkages between aquatic and terrestrial food webs through a study of wolf-killed ungulate carcasses as a resource subsidy to aquatic organisms. Overall, his research aimed to assess possible effects of climate-induced shifts on river ice regimes and predator-prey dynamics.
