K-State Olathe

Sara Gragg

Food Science Professor Sara GraggSara comes to Kansas State University Olathe from Texas, where she earned her doctorate and was a post-doctoral research scientist. Closer once again to her Nebraska roots, Sara's interest in food science and animal science began during her service in FFA and through Ag education. She earned her undergraduate degree from UNL before moving to Texas.

Dr. Gragg's experience with industry complements her academic experience, and is an ideal fit for her position at K-State Olathe, which is at the heart of the thriving Animal Health Corridor.  She has traveled extensively presenting on the topic of food safety and studying processes in food safety and microbiology.

Sara's family is at home in Olathe.
