My academic interests lie in floriculture, greenhouse cropping systems and the physiology of ornamental plants. My research and extension efforts in flower bulb forcing and use are substantially supported by the Dutch flower bulb export industry as well as US companies and Foundations. Findings from my research group have been adopted by many in the floriculture industry worldwide. I also provide leadership for the Seeley Conference, a major floral industry think tank held annually in Ithaca, and I teach courses in herbaceous plant materials and greenhouse management and crop production.
