Steven Chipps
Dr. Steven R. Chipps, Unit Leader-Professor

I serve as the Unit Leader of the South Dakota Cooperative Fish & Wildlife Research Unit. My research interests include feeding ecology and energetics of fishes, and my students and I are currently working on trout management in the Black Hills, and pallid sturgeon ecology in the Missouri River. Originally from Virginia, I attended the University of Idaho (Ph.D.), West Virginia University (M.S.) and Davis & Elkins College (B.S.).
