In the Biophotonics Group, we use light to observe and to understand physiological and biological processes. Currently we are working on fluorescence spectroscopy, nonlinear microscopy, and optical coherence tomography systems (OCT). We are also proud of our outreach programme.
Our fluorescence work is based on a modular all fiber fluorescence spectroscopy system (called the optrode) we have developed. The optrode is now a very versatile tool and it has been applied to the measurement of the heart action potential in vivo, to bioremediation monitoring, and to water safety testing using fluorescence. We have specialised in fluorescence quantification and lately, we have focused on assessing microbiological safety of turbid media.
OCT is an interferometric technique that allows for in vivo imaging of biological tissues with a resolution of less than 10 microns. On top on developing state-of-the-art imaging capabilities, we have successfully worked towards improving the technique itself, in particular through the development of new original signal processing methods. We have also started to use OCT to identify tissues of different natures, adding a layer of functional information to the structural image provided by OCT, and paving the way to real-time optical biopsies.
Our principal aim is to push all our techniques to their limits by understanding how much information you can obtain from the signal after it has interacted with the sample.

Devices for real time bacterial count

FoodSafe is a MBIE funded research programme aiming at developing near real time devices to assess food safety in situ.

Optical biopsies

We work on different aspects of optical coherence tomography from sources to improve the technique itself by extracting as much information as possible from the optical signal.


Our ultimate goal is to develop optical biopsies. 


The Biophotonics Group has an active and effective outreach programme to industry, students and the public.  


We recognize the importance of inspiring, encouraging, guiding, and connecting people with an interest in our technology.
