Natural products chemistry is about the compounds that give colour and flavour to our foods, scent to flowers, and inspiration for many of our life-saving drugs. My research areas are:
New Zealand natural products: working with Māori on discovering new compounds in native plants, animals and microorganisms; by isolation directed by biological assays, and structure identification by combined NMR spectroscopy and molecular modelling. We also study biosynthesis in plants and ecological roles of natural products.
Food bioactives: using NMR, LC, GC, MS and Raman microscopy, to locate and quantify plant metabolites, food bioactives and flavour chemicals; e.g. a stable vitamin C glycoside in apples.
Synthetic organic chemistry (with Bill Hawkins and Dave Larsen): studies on biomolecules to understand the relationship between structure and biological activity, and to produce more active and selective compounds.
My group is part of Plant & Food Research, a Crown Research Institute, with collaborators in other University of Otago departments including Botany and Marine Science, and links to other universities, industry and government researchers around New Zealand and abroad. We collaborate with Ngāi Tahu and other iwi on developing new products from taonga species native to Aotearoa New Zealand.
