Research

I am a Forrest Fellow in the International Centre for Radio Astronomy Research where I am working on developing laser systems for high-precision measurement and high-bandwidth communications between spacecraft and ground stations.

Previously, I was a Postdoctoral Fellow in the Department of Quantum Science at the Australian National University, as part of the Centre of Excellence for Engineered Quantum Systems. I worked on developing  optical phased arrays and other laser systems for metrology and communication.

My PhD research involved the development of stabilized reference frequency transfer systems for the Square Kilometre Array telescope. Stabilized transmission systems are required to synchronize the thousands of radio antennas in the array to the ultra-high precision required for them to act together as one giant telescope, and be able to peer deeper into the cosmos than ever before, allowing astronomers to study the first stars and galaxies that formed in our universe.

You can read about my PhD research here, or listen to me talking about my work on 3-Minute Thesis, ABC Radio National, and The Naked Scientists.
