About Me

Marios Constantinides is a Senior Research Scientist at the CYENS Centre of Excellence, Cyprus, a special teaching staff at University of Cyprus (UCY), Cyprus, and an honorary lecturer at University College London (UCL), UK. He brings over six years of industrial research experience, having held positions at Nokia Bell Labs in Cambridge, UK, and Telefónica in Barcelona, Spain. He was also a research fellow at the University of Cambridge, UK.

His research sits at the intersection of human-computer interaction (HCI), human-AI interaction, and responsible AI, where he designs and develops human-centered technologies that augment how people interact and communicate. His research has been published in leading HCI conferences and general science journals, and his projects have received international media coverage, featuring in outlets such as the BBC, the Economist, the Times, and Fast Company.

Marios is currently serving as the chair of the Cyprus ACM SIGCHI Chapter.
