His research focuses on turfgrass soil, water and nutrient management. He is interested in the relationship between turf crown moisture and temperature stress tolerance. This has implications for turfgrass survival during summer and winter droughts and can result in desiccation of injury and plant death. Other interests include sustainable lawn management, use of nitrogen sensing technology to increase fertilizer application precision, and the cause and management of impermeable iron-oxide layers in sand-based putting greens.
