Ioannis Gkouzionis was born and raised in the city of Thessaloniki, Greece. He received his Diploma of Engineering in Electrical and Computer Engineering from the Technical University of Crete in 2017. After his graduation, Ioannis started studying towards his M.Sc. degree in Electronic and Computer Engineering at TUC, until August 2019. His research focused on Machine Learning methods for the detection and classification of skin lesions in Hyperspectral Imaging. In 2019, Ioannis conducted research at IMEC in Leuven, Belgium in the context of Erasmus internship. There he joined NERF and specifically the FarrowLab led by Prof. Karl Farrow. His research work in that lab focused on the application of Deep Learning methods for the automated segmentation of neurons from confocal images.

Ioannis is currently a PhD Researcher at the Hamlyn Centre for Robotic Surgery and the Department of Surgery and Cancer at Imperial College London. His work focuses on Machine Learning, Deep Learning and Medical Imaging for image-guided interventions and cancer diagnosis and treatment, under the supervision of Prof. Daniel Elson and Dr. Chris Peters. Ioannis aims at solving multidisciplinary problems especially those related to the application of Machine and Deep Learning methods on Biomedical Hyperspectral Imaging.
