I am the Research and Extension specialist for the Nursery industry in Maryland. My expertise is primarily in the areas of water and nutrient management, to reduce the environmental impacts of production practices. However, my interests are very broad and include general plant physiology, plant water relations, soilless substrates, nutrient modeling, production system dynamics and wireless sensor networks. You can access all my current research and extension projects on my Departmental website, from the link below.
