General information

I am currently a Principal Researcher (Grade B') in FORTH-ICS. My research interests lie mainly in the broad areas of Knowledge Representation and Reasoning, Artificial Intelligence, the Semantic Web and Argumentative Persuasion. I have been involved in several projects (mostly European) and published more than 100 papers in various venues. I have received the Best Paper Award in STAIRS-06, the Best Student Paper Award in ISWC-09 and ISWC-15, and the Best Workshop Paper Award in SSWS-18. I am the coordinator of the Symbolic AI Group (SymbAI) of the Information Systems Laboratory of FORTH-ICS.
