Experimental physicist at ICRAR
My research focuses on the development of signal stabilization technologies for the Square Kilometre Array telescope and other space science applications.

A huge range of modern technologies, from GPS to radio-telescopes, rely on the transmission of high-precision time and frequency signals. Over long transmission distances, these signals pick up disturbances that reduce their precision, and so reduce the capabilities of the technologies that depend on them. By developing tools and techniques to overcome this signal degradation, my research will support and enable the next generation of high-precision scientific and industrial instrumentation.
In particular, my research focuses on the application of these technologies to the Square Kilometre Array (SKA) and Atomic Clock Ensemble in Space (ACES) projects. This work will enable the SKA to disseminate frequency references to each of the hundreds of SKA antenna sites at a far lower cost than the standard approach of installing an atomic clock at each antenna site, which would be necessary if suitable signal stabilization technologies cannot be developed. My research will also allow signals generated by atomic clocks at UWA to be transmitted to the Western Australia Space Centre, where they will be compared to atomic clocks on the International Space Station, enabling an improvement in the fundamental and applied science objectives of ACES.

Speaking and Outreach
“Communication is not something you add on to science; it is of the essence of science.” – Alan Alda
As scientists it is imperative that we share our research, not just with each other, but with the public in order to educate, excite, and explain to them what it is we do and why we do it. I take every opportunity to share my science. You can connect with me on twitter @DRG_physics.
I was runner-up in the 2014 UWA 3-Minute Thesis competition, reached the national finals of the British Council’s 2015 FameLab competition, and talked about the Square Kilometre Array at TEDxUWA 2016. I have written blog posts for Australia’s Science Channel, been interviewed on radio and podcasts, and have given talks at schools, community groups and science festivals.
A complete list of my speaking and outreach engagements is available here.
I’m happy to respond to media requests for interviews and expertise on astronomy or physics related topics, and matters of science culture.
Previous credits included: ABC Radio National, ABC 720, RTR-FM, Spirit Radio and Australia’s Science Channel.
