With a keen interest in all things light-related, we have worked in more than one domain. The research in this team ranges from probing objects with modulated light to algorithm application for imaging in various platforms.
Current Projects
Single-pixel and ghost imaging
Novel imaging techniques using “bucket” detectors to measure the signal after the light has interacted with the target and a spatial light modulator.
Optical assessment of skin grafts and flaps
Skin grafts and flaps in postoperative care are assessed with qualitative approaches such as touch and appearance. Research in this domain is keen on identifying quantitative, non-contact approaches to assess the tissue.
ModMicro (Low-cost and modular microscopy) and ModLight (Modular Light Sources)
Modular Microscopy assesses the value of additive manufacturing for low-cost microscopy hardware and techniques.
Modular Light (Certified OSHW Project) sources are a suite of light sources that are LED-based, low-cost illumination strategies.

Biophotonics, Diagnostics and Human Skin Equivalents (HSEs)
Broadly, research in this avenue explores optical assessment and understanding of photon transport in tissue for diagnostics. Our research combines low-cost optical methods, Monte Carlo simulation-based assessments, and experimental methods with microfluidic devices, human skin equivalents (HSEs) and in vivo tissue are the primary focus areas.

Hyperspectral Image Analysis
High-dimensional and high-resolution data is now widely available in remote sensing. We are keen on exploring the dimensionality challenges and spectral investigations for deciphering land-use/land-cover information.
Past Projects
Shoreline change assessment and sea-level rise
Climate change and sea-level rise are two key, related challenges that the world faces today. One of the first areas to be impacted would be coastal regions. Our research looked into assessing past data, including the influencing factors and modelling the coastline to a future position. This approach is key for coastal zone management and planning.
Spectrographs and optical engineering
Optical engineering includes a wide range of research problems, including microscope engineering, spectrograph design, and others.
Our research attempted to recalibrate a proprietary spectrograph system to a separate imaging system and highlights possible avenues of future exploration, presented at the 2018 British and Irish Conference on Optics and Photonics.
