Nutsinee Kijbunchoo

Nutsinee is an experimental physicist with over a decade of experience in gravitational-wave detection and precision optics. Currently a postdoctoral researcher with the OzGrav (ARC Centre of Excellence for Gravitational Wave Discovery) group, her research focuses on understanding gray-tracking in nonlinear crystals, a degradation mechanism that limits the long-term stability of squeezed vacuum sources used in advanced interferometers.

Her involvement with the LIGO Scientific Collaboration began during her undergraduate studies in the US, working on data analysis at the LIGO Livingston Observatory. After graduating in 2014, she joined the LIGO operations team as an operations specialist in 2015, where she played a role in the historic first detection of gravitational waves, monitoring the interferometer from the control room.

Nutsinee completed her PhD at the Australian National University, where she contributed to the installation and commissioning of a squeezed vacuum source at LIGO Hanford, as part of efforts to enhance detector sensitivity beyond the quantum noise limit.

Her expertise spans quantum optics, optical metrology, free-space optical systems, and sensing and control. Her work bridges experimental quantum technologies with large-scale precision instrumentation for fundamental physics.
