Biography
I grew up in Hebron, IL on a family-owned 200-acre ornamental production nursery with my identical twin brother (who is an Associate Dean of Academics at the University of Georgia). Since receiving my Ph.D. my professional experiences have included working as the state vegetable specialist for the University of New Hampshire Cooperative Extension, working on USDA-funded basic research, private consultation with sweet onion growers all over the world, and teaching positions at McHenry County College and the University of Wisconsin-Platteville.
I have taught 17 different horticultural and agricultural course subjects in my career, receiving over 20 teaching awards. I have been recognized as a Distinguished Educator by the Non-land-grant Agricultural and Renewable Resources Universities association and an Outstanding Undergraduate Educator and Fellow of the American Society for Horticultural Science.
I have been a member of the facutly since 2008, but I am also an alum of the Agriculture Department, receiving my B.S. degree in Agribusiness-Horticulture in 1993.
