Higher-order mode displacement sensors
A project to advance a prototype displacement sensor to test-type phase, via improved compact mechanical design, vacuum compatibility, and improved sensor testing.
Fibre optic sensor arrays for vibrometry and acoustic sensing
By leveraging hybrid digital-optical methods, we develop new distributed and quasi-distributed fibre-optic acoustic sensors. These acoustic sensors aim to measure vibration, strain and displacement all while localising the signal source along an optical fibre.
Machine learning for optics and controls
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.
Single side-band modulators for laser interferometric measurements
A topic with a short-term Engineering project and Physics project, to investigate using optical single side-band modulators for interferometric measurements.

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

Dual torsion pendulum for quantum noise limited sensing
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.
Calibrate gravitational wave detectors
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.

Machining learning for coupled interferometer alignment and control
This project aims to develop a three-mirror coupled optical cavity system with automated alignment and control. Machine learning will be used to identify optical modes and optimize cavity operation, enabling advanced studies in precision optical control and interferometry.
Small-package light sources investigation for displacement sensors
Can we use small-package Vertical Cavity Surface Emitting Lasers (VCSELs) or commercial laser diodes for high-performance interferometric displacement sensors?
Vibration control for optical interferometry
Develop an active vibraiton isolation platform to provide a quiet, small displacement environment for high precision inteferometry.
Prospects of future ground-based gravitational-wave detector network
In this project, we study the gravitational-wave astronomy and astrophysics science cases and observational prospects with future ground-based gravitational-wave observatories.
