Dr. Gruys received his BS degree in Chemistry from Gustavus Adolphus College in Minnesota and his PhD in Chemistry (Biochemistry emphasis) from the University of Nebraska-Lincoln. After obtaining his PhD, Dr. Gruys was an NIH Postdoctoral Fellow at the Institute for Enzyme Research and the Department of Biochemistry at the University of Wisconsin-Madison. Dr. Gruys also completed the Stanford Executive Program at the Stanford University Graduate School of Business in Palo Alto, CA.
Dr. Gruys joined KGI after 25 years of R&D experience in the private sector working primarily in the area of Agricutural Biotechnology. Examples of new plant traits he and his collegues discovered and developed during his leadership tenure include oilseeds high in Omega-3 fatty acids, and oil with a high oleic, low polyunsaturated and saturated fat content similar to olive oil. These traits were obtained through plant metabolic engineering, and the high value oil generated by these Biotech crops have both consumer and processor benefits. This and other work of Dr. Gruys has resulted in numerous scientific publications, book chapter contributions and multiple issued patents globally.
Dr. Gruys currently is the Director of the Team Master’s Project, which is the capstone of the KGI Master of Business and Science (MBS) program.
