Jian Liu

Jian Liu is a Research Fellow at the School of Physics, Mathematics and Computing, University of Western Australia, and serves as Program Scientist for Instabilities and Control at the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav). His research focuses on gravitational wave instrumentation, specializing in suppression of high-power instabilities (e.g., angular/parametric instabilities) and quantum performance enhancement in detectors. He leads development of a 2-micrometre cryogenic silicon test mass optical cavity at the Gingin High Optical Power facility.

Education:

• PhD in Gravitational Wave Instrumentation, University of Western Australia (2018)
• MSc, Beijing Normal University (2014)
• BEng, Huazhong University of Science and Technology (2011)

Research Interests: Dr. Liu's work integrates laser optics, quantum measurement, and precision engineering to advance gravitational wave detection. Key areas include optical spring amplification, seismic isolation systems, and noise reduction in interferometers. His collaborations with LIGO-Virgo-KAGRA emphasize real-time detector characterization and multi-messenger astrophysics.

Publications: Recent articles (2020-2025) demonstrate a strong focus on gravitational wave detector optimization, quantum noise suppression, and electromagnetic counterpart analysis. Trends include advanced parametric instability control, cryogenic silicon technologies, and machine learning applications for transient detection. Collaborative works frequently involve multi-institutional teams analyzing LIGO/Virgo observational data.

Advising & Facilities: Actively supervises PhD/HDR students in gravitational wave instrumentation. Primary research conducted at UWA's Gingin High Optical Power Facility, contributing to next-generation detector R&D for global observatories.
