My research interests include nutrition and energy partitioning in perennial plants with emphasis on turfgrasses and woody ornamentals; physiological basis for nutrient acquisition and use efficiency by turfgrasses; turf management strategies for minimizing nitrate leaching to ground water; and physiological control over photosynthate partitioning between shoots and roots.

Current research includes: Turf Management Variables and Their Impact on Nitrate Leaching to Ground Water; Managing Turf with Minimum Nitrogen; and Plasmodesmatal Control over Photosynthate Partitioning between Shoots and Roots.
