Research interests

• Environmental regulation of carbon assimilation and metabolism (i.e., source-sink relationships)
• Whole plant growth dynamics
• Impact of environmental stresses on phytochemistry, growth and development
• Plant growth regulation and the use of exogenous plant growth regulators
• Soil fertility and plant nutrition dynamics and the subsequent impact on symbiotic relationships, plant growth, development, yield and fruit structure and composition
