Professor Sarah Barman

About

I am Professor of Computer Vision within the School of Computer Science and Mathematics. My research interests include the development of computer vision techniques applied to medical images. Our team has developed algorithms to detect vessel morphology and pathologies on retinal fundus images over the last ten years and previous work includes the development of ophthalmic analysis software resulting in US FDA approval. Current projects are focused on the application of deep learning to both ophthalmic and oral lesion images. I am a member of the UK Biobank Eyes and Vision Consortium and a Fellow of the Institute of Physics.
