Paul Altin

Dr. Paul Altin is a prominent researcher at the Australian National University's Centre for Gravitational Astrophysics within the Research School of Physics. His work focuses on gravitational wave physics, quantum optics, and dark matter detection, with significant contributions to major international collaborations including LIGO, Virgo, and KAGRA.

His research interests span gravitational wave detection techniques, quantum measurement science, and dark matter searches. Altin has made substantial contributions to gravitational wave data analysis, particularly in continuous wave searches and compact binary coalescence studies. He is also deeply involved in the ORGAN experiment, which searches for axion-like dark matter particles using high-precision microwave cavity techniques.

Analysis of his recent publications reveals a strong focus on gravitational wave astronomy across multiple observational runs (O3, O4), with particular emphasis on multi-messenger astronomy, continuous wave detection, and dark matter searches. His work bridges theoretical astrophysics with cutting-edge experimental techniques in quantum measurement.

Altin is an active participant in numerous international collaborations, contributing to major gravitational wave discoveries including binary black hole mergers, neutron star-black hole coalescences, and dark matter constraints. His research spans both theoretical analysis and experimental instrumentation development.

He is a key member of the Atom Laser group at ANU, working on advanced quantum measurement techniques for gravitational wave detection. His work on cryogenic systems and low-vibration environments supports the development of next-generation gravitational wave observatories with improved sensitivity.
