West Virginia Staff Member
- MS West Virginia University 2013
Ryan received a BS from West Virginia University in Wildlife and Fisheries Resources in 2004. While attending WVU, he had the opportunity to work on a variety of projects generally using an ecosystem-based approach for the conservation of native freshwater species in the Central Appalachian region. Following graduation, he worked in the Inter-mountain West and the Pacific Northwest focusing on a variety of marine groundfish, anadromous salmonid and freshwater species projects.
Ryan’s research interest is focused primarily in stream ecology and management. His recent interest is in fish physiology and histology. He is currently part of a comprehensive fish health assessment in the Great Lakes drainage with specific research focusing on non-specific genetic toxicity by evaluating for the presence of micronuclei in peripheral erythrocytes. His long term research interests are geared at the pairing of spatial data with histopathological and genetic endpoints to better evaluate and manage impaired systems.
