Dr Ling (Lilli) Sun

Research Fellow, Centre for Gravitational Astrophysics, The Australian National University

I am a research fellow at the Centre for Gravitational Astrophysics (CGA) at the Australian National University. I am a member of the Laser Interferometer Gravitational-wave Observatory (LIGO) Scientific Collaboration and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav).

My primary research interests are gravitational-wave data analysis and studying fundamental physics from gravitational-wave observations, including:

  • continuous waves from neutron stars

  • gravitational waves from ultralight boson condensates around black holes

  • post-merger process and remnants of binary neutron star mergers

  • calibration of the gravitational-wave detectors

In particular, I am interested in bringing together the advanced computing and signal processing techniques, gravitational-wave data and theory, as well as the understanding of the instruments for gravitational-wave observation.
