Senior Research Fellow

Biography

I am a research scientist in the Photon Factory in the School of Chemical sciences at the University of Auckland. I earned my PhD in Raman spectroscopy of passive film on iron film with electrochemical control from The University of the Witwatersrand in Johannesburg, South Africa, where I also earned a BSc (Hons) in Chemistry and Applied chemistry. I also graduated with MSc in Physical Chemistry from the University of South Africa, Pretoria, South Africa.

I specialise in the use of vibrational spectroscopy (Raman and infrared spectroscopies (Mid, Near- and Far-IR) and chemometrics to analyze a wide variety of materials. I have published over 40 publications in peer-reviewed journals and proceedings, and regularly reviews articles for three different journals and beamline proposals for the Australian Synchrotron

Research | Current

My current research focuses transforming large, complex datasets into knowledge and insight. In particular, she combines multi-modal spectroscopy (Raman, IR, SERS, fluorescence, absorption, etc.) and multivariate data exploration, classification and quantification approaches to determine the detailed composition of complex fluids like milk (detailed nutritional and animal health information; adulteration detection) and solid samples such as skin lesions (identifying and typing for malignancy). The advantages of this combined approach of multivariate data analysis and spectroscopy allows interrogation of materials in situ, without changing the sample matrix. This powerful combination thus enables not only quantitative and qualitative analysis of minor components in complex matrices, but the interactions between the components in their environment as well.

I am also a collaborator in a number of other research projects in the School of Biological Sciences, School of Chemical Sciences, School of Pharmacy and School of Engineering, in the use of vibrational spectroscopy (Raman and infrared spectroscopies, Mid, Near- and Far-IR) and chemometrics to investigate the composition and behaviour of a wide variety of materials.
