Laser Physics

PhD Laser Physics / Laser Flow Cytometry

5 years research work including a final thesis outline.

Withdrawn due to business commitments, see Professional Experience (Spinifex Technologies / dSP – Digital Studio Processing).


Macquarie University, North Ryde, NSW, Australia.




During my PhD I developed a new technique allowing for the first time, the use of pulsed lasers in laser flow cytometry. I drafted a provisional patent which was applied for on behalf of the University.

The second achievement was being able to image every individual cell in a flow cytometer using high sensitivity cooled CCD detectors and high repetition rate pulsed lasers. Previous research had captured images of cells in flow, but we were the first to allow image capturing of EVERY cell in a given sample.

The final major achievement was toward the end of my research work, I lead the technical instrumentation team applying Laser Flow Cytometry to detect Cryptosporidium and Giardia parasites in drinking water. The techniques we developed were published and are still being used today by water authorities around the world.

I was also involved in the commercialisation of other technology in the Centre for Lasers and Applications during my time at the University.

Along with the basic course work, I was awarded two university prizes for my work in practical laser physics. A co-student and I developed a technique for traffic (car movement) detection using optical fibres. The technique was patented by the University and I was involved in drafting the patent as well as finding and working with a company to commercially develop the technology.
