Theodoros Pissas

PhD student / Research Assistant


I am a PhD student at the Wellcome EPSRC Centre for Interventional and Surgical Sciences at UCL under the supervision of Christos Bergeles and Lyndon Da Cruz. I am also research assistant at the Robotics and Vision in Medicine lab at King’s College London. My research focus is the development of systems utilizing deep learning-based computer vision in order to and assist high-precision retinal microsurgery delivery. More specifically, my research interests lie in semantic segmentation of pre-operative and intra-operative images and multimodal image registration. I am also interested in weakly supervised and self supervised learning for medical image analysis with the goal of tackling the hurdle of obtaining labeled data in this domain. Prior to joining UCL in October 2017, I completed my undergraduate studies (joint MSc and BSc) at the National Technical University of Athens. During my diploma thesis I worked on human action recognition using deep learning.
