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 one of the Chief Investigators of 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
ringdown of binary black hole mergers
calibration of the gravitational-wave detectors
science of the next-generation detectors
In particular, I am interested in bringing together advanced computing and signal processing techniques, gravitational-wave data and theory, as well as the understanding of the instruments for gravitational-wave observation.
