Dr Gravel's expertise is in the area of sustainable horticultural production systems with a specific emphasis on sheltered or greenhouse crops. Research interests include: nutrient availability and plant uptake in organic cropping systems, plant growth regulation in sustainable production sytems, microbial interactions within the soil-plant-environment continuum, and biological control of diseases and pests in sustainable fruit, vegetable and ornemental crops.
