Fields of Research

  • Control of flowering and perenniality
  • Developmental plant physiology
  • Plant hormone homeostasis
  • Plant hormones in growth and development

Researcher Summary

Research interests are:
- Developmental plant physiology with particular interests in the roles of the plant hormones in growth and development. Current research includes projects on phase change, flowering, pigments, fruit development and senescence
- The interaction between the environment, the physiology and the molecular biology underpinning flowering and perenniality in native species
- Plant-microbe interactions with a particular focus on the perturbation of plant hormones by the microbe and the mechanisms invoked by the plant to retain hormone homeostasis
