Benjamin Dix-Matthews is a Research Associate at the University of Western Australia, working on the stabilisation of free-space optical links for metrology, geodesy, and communications. Benjamin’s research has focused on applying optical phase-stabilization technologies to ultra-stable optical transmissions through the atmosphere for use in high-speed communications, geoscience, and fundamental physics. His work has produced cutting-edge techniques for orbitography, optical clock comparisons, and high-speed optical communications.
