Biography
Originally hailing from Richmond Virginia, Dr. Dunn is the Leader of the North Carolina Cooperative Fish and Wildlife Research Unit and previously served as an Assistant Leader of the Mississippi Unit. Before joining the Cooperative Research Units program, Dr. Dunn received his B.S. and M.S. degrees from Virginia Tech, his PhD from the University of Missouri, and was a postdoctoral researcher at Mississippi State University. Growing up on the Fall-line part of Virginia exposed him to the many species of migratory fishes that use the area's shoals for spawning habitat. Consequently, Dr. Dunn became a stream-river fisheries biologist who has worked on conservation issues spanning ephemeral headwaters to the Mississippi River. His main research area is the ecology and conservation of rivers and riverine biota. This overarching theme encompasses several research areas including ecology of large-river fishes, endangered species management, invasion ecology, and riverine landscape ecology. Dr. Dunn has taught several courses, including Ecology of River Systems, Structured Decision Making, Native Species Conservation, and Fisheries Sampling Techniques.
