The subject of my PhD thesis is "Temporal and spatial knowledge representation on RDF databases". I've received my B.Sc in Computer Science from DI&T, NKUA in 2007 and my M.Sc. in Computer Systems Technology from the same department in 2010. Since 2008, I am a member of the Management of Data and Information Knowledge Group (MaDgiK).
