I joined the Surgical Robot Vision group in 2017, and I work on multimodal optical and computational imaging methods for enhanced surgical guidance and clinical decision-making. My research area is biophotonics, the study of light-tissue interactions, and its application in medicine. I received my PhD in Physics in 2009 from the University of Limerick, where my project involved tracking changes in skin mechanical properties. I subsequently moved to the Hamlyn Centre and Department of Surgery and Cancer at Imperial College London, where I began developing imaging tools for minimally invasive surgery. I have used multispectral imaging to monitor changes in oxygen saturation (liver, bowel, and transplantation surgery), hyperspectral reflectance and autofluorescence imaging for tissue classification (colonoscopy), polarisation imaging to enhance visibility of superficial vessels (abdominal surgery), and structured light profilometry to measure organ shape (head & neck, bowel surgery). These modalities have been further enhanced by computational methods for motion compensation, hardware optimisation and real-time processing. My current work involves studies of organ perfusion during colorectal surgery, in partnership with surgeons at UCLH.
