For gravitational-wave detections and analyses, the raw outputs from the gravitational-wave detectors need to be converted into analysable data through some calibration apparatus. This project investigates new techniques to improve calibration accuracy and precision and better integrate the calibration bias into astrophysical analyses. 

Construct a small dual tosion pendulum which have their centre of mass co-incide and their rotational axis colinear. Inital diagnostics will be done using shadow sensors.

Gravitational wave detectors have reached the thermodynamic limit of optical coating performance and require novel coating materials and coating noise suppression techniques for further sensitivity improvements. This project is to design a high-bandwidth feedback control system to stabilise the intensity and frequency of a 2µm-band laser for investigations of thermal noise in experimental mirror coatings.

Optical cavities are widely used in physics and precision measurement.  This project will explore the use of modern machine learning methods for the control of suspended optical cavities.

In this project, we study the gravitational-wave astronomy and astrophysics science cases and observational prospects with future ground-based gravitational-wave observatories.

Using non-classical light states on laser interferometric gravitational-wave detectors, to further enhance the best length measurement devices in the world.

Gravitational wave detectors have reached the thermodynamic limit of optical coatings. Further sensitivity improvements require new coating materials and noise mitigation techniques. This project models the behaviour of higher order spatial laser modes in optical resonators for measuring coating thermal noise directly.

Develop an active vibraiton isolation platform to provide a quiet, small displacement environment for high precision inteferometry.
