Welcome

My name is Marios Belk, I work in the fields of Human-Computer Interaction and Human-Centered Computing. I received a PhD in Computer Science (Dec. 2015) from the University of Cyprus (#84 World's Best Young University 2020 - Times Higher Education).

I am co-founder and CEO of Cognitive UX GmbH, Heidelberg, Germany, which is an IT company aiming to develop AI-driven and human-centered cybersecurity and privacy systems. I am also a Visiting Lecturer at the Department of Computer Science, University of Cyprus, and an Adjunct Lecturer at the Open University of Cyprus within the Cognitive Systems Master's programme.
