I received a BSc degree in computer science from Aristotle University of Thessaloniki, Greece, in 2001 and the MSc and PhD degrees from the University of Surrey, in 2003 and 2006, respectively, both in electrical engineering working on registration. From 2001 to 2002, I held a research position at Aristotle University, working on image and video watermarking. I joined the Communications and Signal Processing (CSP) Department, Imperial College, London, in 2007 where I was a Research Fellow working on 3-D object reconstruction. Now, I am Professor at Kingston University working on computer vision and AI for crowd and human behaviour recognition, anomaly detection, scene analysis, and serious computer games for medical applications. Also research is conducted on AI-powered augmented and virtual reality (AR/VR) systems.
