Daniel Brown

Dr. Daniel Brown is an ARC Grant-Funded Researcher B in the Physics department at the University of Adelaide. His research focuses on cutting-edge gravitational wave astronomy, detector technology, and quantum optics. He contributes to major international collaborations including LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo, advancing detector sensitivity and data analysis methodologies.

Key areas of focus include improving interferometer performance through quantum noise reduction, identifying gravitational wave signals from compact object mergers, and analyzing detector noise characteristics. Dr. Brown has pioneered work on transverse mode control in quantum-enhanced interferometers, and contributed to studies of thermal lensing effects in LIGO test masses using machine learning approaches.

His work spans experimental astrophysics, with notable contributions to gravitational wave observations of neutron star-black hole coalescences. He also explores dark matter models using gravitational wave data from KAGRA detectors and investigates lensing effects in multi-detector networks. Dr. Brown actively participates in the development of next-generation gravitational wave observatories like the Einstein Telescope.

Dr. Brown's research outputs include over 50 peer-reviewed articles, with recent emphases on: improving LIGO's noise performance in O4 runs, analyzing ultralight vector dark matter, and developing novel techniques for point absorber detection in optical systems. He collaborates internationally with institutions like the Max Planck Institute for Gravitational Physics and the Virgo Collaboration.
