Exploring fundamental physics with gravitational waves


The Project aims to develop new theoretical techniques and utilise them to model and analyse various gravitational wave signals within the alternative theories of space, time and matter.

Program type



The recent breakthrough discovery of gravitational waves by LIGO Collaboration has opened a whole new avenue for understanding of some of the most fundamental aspects of the universe. In particular, several well-motivated extensions of the Einstein General Relativity and standard cosmology may now become testable in the strong gravity regime through the measurements of gravitational waves at current and future facilities worldwide. However, while the gravitational wave signals and their sources are relatively well studied within the Einstein theory of gravitation, alternative theories remain less explored. This Project aims to fill this gap by providing a significant theoretical input for interpreting the observations and opening unique opportunity for exploring new physical phenomena and theoretical ideas, such as alternative theories of gravity, exotic compact objects composed of dark matter and cosmological phase transitions in the early universe.

- Confidential disclosure of a pre-existing or current medical condition that may hinder your performance in your degree (e.g. heart disease, pace-maker, significant immune suppression, diabetes, vertigo, etc.);
- Ability to perform independently and/or with minimal supervision;
- Ability to undertake certain physical tasks (e.g. heavy lifting);
- Ability to undertake observatory, sensory and communication tasks;
- Ability to spend time at remote sites (e.g. One Tree Island, Narrabri and Camden);
- Ability to work in confined spaces or at heights;
- Ability to operate heavy machinery (e.g. farming equipment);
- Hold or acquire an Australian driver’s licence;
- Hold a current scuba diving license;
- Hold a current Working with Children Check;
- Meet initial and ongoing immunisation requirements (e.g. Q-Fever, Vaccinia virus, Hepatitis, etc.)

You must consult with your nominated supervisor regarding any identified inherent requirements before completing your application.
