Optical coherence tomography is an imaging method best described as “ultrasound but with light”.  It is a non-invasive imaging technique that allows for rapid subsurface imaging of the skin, allowing us to reveal key health properties. 

It is known that ultraviolet light exposure causes melanoma. However, it is not clear whether there are other environmental factors acting along with ultraviolet radiation. This study investigates the role of organochlorine compounds, found in the environment, in melanoma development.

This multi- institute project (InterMEL consortium project) identifies molecular and clinical factors which relate to the prognosis of melanoma, with the ultimate objective of improving the treatment of advanced melanoma.

Polarization speckle is a noise-like interference pattern created when a skin lesion is illuminated by laser light.

In this project, we develop a handheld and easy-to-operate optical probe for detecting melanoma. Delivery of the technology is aimed at non-dermatologist healthcare providers, improving their diagnostic accuracy and reducing the number of referrals to the specialists.

Computer-aided systems for melanoma - The objectives of this project are to develop automated computer systems to help interpret complex dermoscopic images with the ultimate aim of distributing the technique to non-dermatologist healthcare providers and, maybe, even patients.
