Associate Professor (Biological Sciences)

Qualifications: BSc, MSc(Hons) Auckland, PhD Edinburgh

Research Interests

Plant vascular transport and carbon and water physiology, with a focus on the role of vascular functioning in the development of flowers and fruit. Current research projects include the flowering phenology and physiology of nectar production in mānuka (Leptsopermum scoparium), water use by Hass avocado, fruit growth and flavour development in kiwifruit, and the environmental physiology and ecology of New Zealand native trees.
