About Me


My name is Giannis Haralabopoulos. I am a computer scientist from Greece, interested in Human Computer Interaction, Data Science, Natural Language Processing and Machine Learning. I currently work as a Research Fellow at the University of Nottingham.

I received my Ph.D. from University of Thessaly in 2016. My thesis title was "Online social networks: real-time graph sampling, multilayered information diffusion, and equality issues". My early studies were completed in the beautiful island of Samos at the University of the Aegean, from where I received my B.Sc. in Mathematics, 2009, and my M.Sc. in Computer Science, 2011.

You can find my publications and a selection of conferences, images and datasets below. Clicking on the title of a publication will redirect you to its hosting domain. On the bottom of the page you will find my contact details and links for social and academic media.
