Extension (80%) and research (20%) responsibilities for commercial floriculture.

Research: diagnostics, plant nutrition, water quality, plant growth regulators, and economics.

Extension: Focus includes providing production information and diagnostic services to commercial greenhouse floriculture operations.  Area of specialization includes plant nutrition, plant growth regulators, and problem diagnostics.  Primary crop focus includes pansies, bedding plants, poinsettias, and general potted plants.
