General information
I am a Research Director (Grade A') 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,
SEMAPRO-22 and others). I am the coordinator of the Symbolic AI Group (SymbAI) of the Information Systems Laboratory of FORTH-ICS.
