My research aims to push the limits of precision measurement for both fundamental and applied research. Liaising with industry and defence has made my research have real-world impact through development of measurement devices for use outside the laboratory. I have supervised the development of a number of experiments: compact high-stability optical clock, an optical magnetometer, and high-resolution molecular spectroscopy, and atomic spectroscopy within hollow core fibre. I'm now applying this knowledge to a biological setting to extract maximum information from biological systems utilising optical techniques.

I was awarded my PhD almost in 2014 from the University of Western Australia. After submission of my thesis, I accepted a University Research Associate position at the University of Adelaide within the Institute for Photonics and Advanced Sensing (IPAS).

Please see my research group's website.

Work I'm currently working on:

  • Optical Trapping: We develop novel trapping techniques to observe, measure and analyse biomechanical properties in the fertilised embryo to non-invasively quantify embryo quality and health
  • Speckle Measurements: Light scattered off a surface resultant interference pattern has a grainy appearance which we call speckle. This speckle is often considered as a loss of any information contained in the laser light. However, the speckle is actually rich in information about both the laser properties, environment, and the scatterer. We have used this phenomenon to perform highly accurate measurements of laser parameters, such as attometre-resolved wavelength measurement and characterisation of the orbital angular momentum and polarisation of the light beam.
  • Low Light Imaging: Imaging of biological samples typically requires low light levels to ensure the sample is not damaged. We are exploring what the best methods are to create high resolution and high signal-to-noise images in low-light conditions.

Previous projects I've worked on:

  • Compact High-Stability Optical Clock: I led the development of an optical clock based on a two-photon transition within rubidium which is performing at the same level as the best commercially available frequency standard (the Hydrogen maser), while being 10-fold smaller and lighter. This is possible through using two different colour photons to excite the two-photon transition, leading to an increase excitation efficiency of a million-fold. This technology is breaking the nexus between size, weight and performance of optical clocks.
  • Optical Magnetometry: We developed two optical magnetometers for defence and industry applications. I have pioneered techniques to greatly increase the bandwidth of DC atomic magnetometers broadening their practical applications. These magnetometers have been tested outside the lab in real world environments.
  • High-Resolution Molecular Spectroscopy: We are developing a trace gas spectrometer based on a laser frequency comb light source and high precision absorption measurement. We have demonstrated a measurement accuracy of 1% and a precision of 0.04% for measurement of the number density of the common isotopes of Carbon Dioxide. We are applying this to biological samples, to measure Carbon Dioxide produced from yeast, leading up to measurements of biomarkers in exhaled breath for medical diagnostic applications.
  • Non-Linear Spectroscopy: I was the first to show strong light-light interactions within large-diameter hollow-core fibre, achieved through exciting a two-photon atomic transition of the atoms. This has been utilised to perform quantum memories and frequency conversion within hollow-core fibre for quantum information processing.
