Biography

Biography

Prior to being appointed to Deakin’s School of Life and Environmental Sciences as an Alfred Deakin Postdoctoral Research Fellow (ADPRF), I have completed 2 postdoctoral fellowships at RIKEN (The Institute of Physical and Chemical Research, Japan) and Monash University (Clayton). My main expertise is vibrational spectroscopy including Fourier transform infrared (FTIR) and Raman technique, and synchrotron-FTIR microspectroscopy.

With the highly growing demand in the consumption of omega-3 polyunsaturated fatty acids (n-3 PUFAs) particularly for DHA and EPA, my main research interest at Deakin has been focused on developments of FTIR microspectroscopic technique and chemometric approaches for rapid non-invasive, potentially on-line, monitoring of n-3 production in novel microencapsulated fish oil (uEFO) supplements and marine fungoid protist thraustochytrids–a potential alternative vegetarian resource for n-3 PUFAs other than fish oils.

High-resolution FTIR and Raman imaging analysis further provides unique information on the distribution of biological macromolecules (i.e. lipids, proteins, carbohydrates and nucleic acids) and other vital components such as chlorophyll and carotenoids. The technique requires only minimal sample preparation and the spectral image can be acquired directly from the micron-sized intact cells and encapsulated fish oil powder in non-invasive fashion.

The use of synchrotron-FTIR microspectroscopy particularly provides an exceptional advantage due to the superior characteristics of the highly intense synchrotron-IR radiation that allows in vivo examination of individual live cells directly from the growth medium without any sample preparation. Together with chemometric methodologies, information of chemical variation within cell populations can be assessed to provide a mean for quality control standardization, and potentially leads to quantification of PUFA compositions in the cells.
