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, (Symbolic) Artificial Intelligence, Semantic Technologies and Knowledge Graphs. I
have been involved in several projects (mostly European) and published more
than 150 papers in various venues. I have received awards for co-authored
publications in various conferences (including STAIRS-06, ISWC-09, ISWC-15,
SSWS-18, CLAR-21 and others). I am the coordinator of the Symbolic AI Group (SymbAI)
of the Information Systems Laboratory of FORTH-ICS.
