Structured Light
Research focuses on vector vortex beams carrying spin and orbital angular momentum (SAM & OAM), polarisation and phase singularities, topology, etc.
Optical Skyrmions
Research focuses on the fundamental study of topological quasi-particles through spatially varying polarization fields, as well as their applications in computing and beyond.

Adaptive Optics
Research focuses on full vectorial adaptive optics or its subset, encompassing feedback correction for intensity, phase, and polarization aberrations. Applications span across biomedical imaging, direct laser writing, and beyond.
Passive Compensation
Research focuses on the practical application of passive devices to compensate for vectorial aberrations or their subsets.

Polarisation Sensing/Imaging
Research focuses on partial/full Stokes vector or Mueller matrix measurement methods, including calibration, optimisation, and denoising approaches.
Phase Measurement
Research focuses on the methods to measure and retrieve the phase properties of the light beams. The combination of sensing intensity, wavelength, phase, and polarization aligns well with our research interests.
