Prof Julian Heyes PGDipDevStud, PhD, BSc(Hons)

Head of School of Food and Advanced Technology

Doctoral Supervisor
School of Food and Advanced Technology

I have also applied my knowledge to support small farmers in developing countries who are seeking higher-value market opportunities. For four years I was Chair of the International Society for Horticultural Science Commission on Fruit and Vegetables for Health, and this topic has driven many of the research projects of my PhD students. I have acted as chief- or co-supervisor for 23 students who have completed their PhDs since 2009.

I am a Fellow of the New Zealand Institute for Agricultural and Horticultural Science (and its Vice President) and Life Member of the New Zealand Society of Plant Biologists. I am an Adjunct Professor in the University of Mataram, Indonesia. My DPhil in plant physiology came from the University of Oxford, where I was a Rhodes Scholar.

I am the Head of the School of Food and Advanced Technology and my discipline is postharvest physiology: the science behind our global trade in fresh fruit, vegetables and cut flowers. My strategic research interests lie in connecting science to growth of the New Zealand bioeconomy, based on high value products and technologies particularly from the horticulture sector.

Project Title: Metabolomics for health

'A diet rich in fruit and vegetables has been shown to reduce the risk of coronary heart disease': this is one of the few pre-approved high-level health claims that is permitted under New Zealand and Australian food labelling legislation. But what is it in our fresh fruit and vegetables that helps to keep us healthy? We know that the list includes vitamins, minerals and nutrients; and we know that dietary fibre has a huge role to play in maintaining good health. But there are also tens of thousands of phytochemicals: small bioactive molecules that trigger protective responses in our body and may help us fight all kinds of disease. Historically research in this area has been slow as we focus on one chemical at a time. In this project we adopted a non-targetted 'metabolomics' approach, measuring 'everything that moves' in simple carrot extracts using nuclear magnetic resonance, and then we let the computer tell us what was different between particular samples. This approach can be used to screen (for example) extracts from different cultivated varieties of a single vegetable that are known to have different "bioefficacy". This preliminary study was carried out jointly with Plant & Food Research and has led to ongoing research trying to match particular carrot varieties to particular health outcomes.
