Royal Commission for the Exhibition of 1851 Research Fellow
My main research interest is control of the spatial structure of light, by developing dynamic waveguide circuits. Dynamic optical circuits on waveguide “chips” will be capable of routing and processing information as light. These circuits will enable a faster and more efficient internet, probe the limits of light’s quantum nature, and help unravel its propagation through complex environments such as miniature endoscopes and biological tissue. This project is supported by a Research Fellowship from the Royal Commission.
I also work on many aspects of the microscopy and spectroscopy work we do in the Nanophotonics Centre, particularly where experiments must be automated to collect data on thousands of individual nanoparticles. I have developed an automated microscope produced using 3D printing, capable of sub-micron positioning, which is now being commercialised by WaterScope to provide low-cost diagnostics for developing nations.
My PhD was in optical tweezers, supervised by Prof. Miles Padgett at the University of Glasgow, where I developed a number of optical tweezers systems using high-speed cameras and spatial light modulators. My control program for hologram generation "Red Tweezers" is available online, and I helped design the optical tweezers system sold by Meadowlark Optics.
