I am an Imperial College Junior Research Fellow in the Department of Surgery and Cancer, and the Hamlyn Centre for Medical Robotics. My research activities are centred around the development of optical technologies that can be used in minimally invasive diagnosis and surgery. These methods aims to give more feedback to the clinician in the form of structural and functional information on the health of the tissue. This includes classification of tissue pathology, oxygenation mapping, blood flow/perfusion and detection of structural abnormalities.
Some of my current work is outlined in the table below.
|Hyperspectral & Multispectral Reflectance and Fluorescence Imaging||Detection and identification of diseased tissue; endoscopic polyp identification|
|Polarisation Imaging||Depth-sensitive vessel identification; detection of abnormal tissue development|
|Multispectral Oxygen Saturation Mapping||Intraoperative perfusion monitoring: organ transplantation, bowel anastomoses, arterio-venous fistulae|
|Simultaneous Multispectral and 3D Imaging||Correction of in vivo motion artefacts; deblurring|
|Structured Light 3D Imaging||Deformation recovery; augmented reality|
|Liquid Lens-Based Endoscope||Gaze-contingent autofocus|
Previous work has involved the development of a device to detect changes in the skin's mechanical properties using an indentor and optical tracking system. Other work on the skin included monitoring red blood cell concentration using polarisation spectroscopy and following the response of the microcirculation to compression and irritation.
I am a graduate of the University of Limerick in Ireland, where I received my BSc in Applied Physics, followed by a PhD in 2009.
