I work as a research associate in the biophotonics group in the Hamlyn Centre at Imperial College London. My work primarily involves the design, construction and application of optical devices for use in minimally invasive surgery (MIS). This includes:
• Measurement of tissue oxygenation
• 3D surface shape measurement
• Correction of motion artefacts in multispectral image stacks
• Application-specific surgical light sources
• Polarisation imaging
• Gaze-contingent autofocus
• Fluorescent gold nanoparticle detection
A number of these techniques have been trialled in vivo in applications such as bowel oxygenation imaging, perfusion imaging during organ transplant procedures, examination of vascular anastomoses and contrast enhancement during MIS examination of the abdomen.
I am also interested in advanced image analysis algorithms for structured light detection, pattern recognition, modelling of light propagation in tissue and 3D reconstruction of tissue surface shape.
