Research | Current

Bruno's research focuses on isolation, identification and analysis of molecules from biological samples. Mass spectrometry based techniques are used for structure elucidation and the development of analytical methods to quantify molecules of biological and/or technological interest.

The main area of research is the study of the secondary metabolites in grape and wine, even though current projects on honey, dairy products, etc. are currently undergoing. The research developed in Bruno's lab stretches across a variety of chemical fields such as analaytical chemistry and organic synthesis. These projects are developed to gain fundamental knowledge on the biosynthesis and significance of these compounds in natural products as wellas to provide important applicable insight to several NZ industry sectors.
