David Kuhn, PhD
David Kuhn, PhD, is an associate professor and extension specialist in the Department of Food Science and Technology at Virginia Tech in Blacksburg, Virginia. He has earned B.S. degrees in Mathematics and Civil Engineering and a M.S. and a doctorate degree in Civil and Environmental Engineering. He maintains an aquatic laboratory on the main campus at Virginia Tech. In addition to conducting research projects in the laboratory (topics such as aquacultural engineering, biotechnology applications, alternative nutrition, animal health, and food quality) he has also served as a principal investigator on sponsored projects at nine privately owned aquaculture facilities that culture finfish, shrimp, oysters or clams. Conducting research in these public-private partnerships brings a unique and practical aspect back to his research and outreach programs.
