Doctoral Candidate - Doctor of Philosophy


I am a second year PhD student of Physics at University of Auckland and I also hold a Master degree in Physics from the University of Glasgow. I possess excellent leadership, networking, communication and problem-solving skills with proven ability to manage and complete projects to the highest standard, with a careful attention to details and within agreed targets.

Research | Current

My current research focuses on the development of microfluidic devices for flow cytometry study of bacteria cells. In this research, microfluidic devices which incorporates hydrodynamic flow focusing using sheath flow are fabricated to achieve single-cell focusing of stained bacteria cells. Fluorescence imaging is then applied to analyse the width of the flow-focusing stream of bacteria cells at different flow velocities to ensure single-cell analysis using a focused laser beam. Fluorescence imaging analysis have been used to determine the optimised flow-conditions for single-cell focusing of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) in the fabricated microchannels which has been instrumental in the improvement of the limit of detection of the microfluidic flow cytometry system. This work will enhance the rapid and accurate detection of bacteria cells to improve health and food safety in New Zealand. I work under the supervision of Associate Professor Frederique Vanholsbeeck, Dr. Cushla McGoverin and Associate Professor Simon Swift.
