Rate My Professor Bram Slagmolen

Associate Professor Bram Slagmolen serves as Senior Fellow and GW Laboratory Manager for Gravitational Wave Detection at the Centre for Gravitational Astrophysics within the Research School of Physics at the Australian National University. He obtained his BSc in Photonics from TH Rijswijk, Den Haag, Netherlands, in 1998, and his PhD from the Australian National University in 2005. His early career included a position as Project Scientist at the University of Western Australia's Gingin facility from 2003 to 2004. Slagmolen held an ARC Australian Postdoctoral Fellowship from 2007 to 2009 and an ARC Future Fellowship starting in 2013. In 2023, he was elected Fellow of the American Physical Society for the development of technologies for gravitational wave detectors. He previously chaired the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA), which preceded OzGrav, and serves on the Multi-Messenger Astronomy Advisory Committee (MMAAC) advising the board of Astronomy Australia Limited.

Slagmolen's research specializations include the development of measurement technologies and hardware implementations for gravitational wave detection, particularly for the Advanced LIGO project, based around optical laser interferometry. Current interests focus on sensors for low-frequency gravitational force signals due to seismic and atmospheric disturbances, as well as new technologies to improve the performance of current and future gravitational wave detectors. Notable achievements encompass commissioning the first 4 km optical cavity at LIGO Hanford Observatory to test the arm length stabilisation system and designing and managing the delivery of 30 Tip-Tilt small optic suspensions to Advanced LIGO, now used to direct the laser beam onto photodiodes registering gravitational wave signals. Key publications include "Advanced LIGO detector performance in the fourth observing run" (Physical Review D, 2025), "A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-wave Candidates from the Third Gravitational-wave Observing Run" (The Astrophysical Journal, 2024), "Automated alignment of an optical cavity using machine learning" (Classical and Quantum Gravity, 2025), "Low-vibration cryogenic test facility for next generation of ground-based gravitational-wave observatories" (Review of Scientific Instruments, 2025), and "Tip-tilt mirror suspension: beam steering for advanced laser interferometer gravitational wave detectors" (Review of Scientific Instruments, 2011). His contributions have significantly advanced gravitational wave detection capabilities.
