Nikolaos Stylianou

I am a Postdoctoral Research Fellow at the Information Technologies Institute of Center for Research & Technology Hellas, in the Multimedia Knowledge and Social Media Analytics Laboratory, part of the M4D group.

Previously, I earned my Ph.D. in Natural Language Processing from Aristotle University of Thessaloniki, under the supervision of Ioannis Vlahavas as part of the Intelligent Systems Lab @AUTH. Before that, I received my B.S. in Computer Science from University of Essex in 2014 and my M.S. in Big Data and Text Analytics from University of Essex in 2015, where I worked with Udo Kruschwitz and Massimo Poesio.

My research is focused on Natural Language Processing and Machine Learning. Specifically, I am interested in Information Extraction, Language Modelling, Multimodal Learning and Self-Supervised learning. If you are interested in collaborating, feel free to reach out.
