Mass spectrometry based techniques are used for structure elucidation and the development of analytical methods to quantify molecules of biological and/or technological interest. Main area of research is the study of the secondary metabolites in grape and wine (cf Wine Science Programme), even though current projects on honey, dairy products, etc. are currently undergoing. Strong collaborations with David Barker allow to extend this field of research to the total synthesis of the molecules of interest. These projects are developed to gain fundamental knowledge on the biosynthesis of these compounds in natural products and to provide important applicable insight to several NZ industry sectors.
