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
