Short Bio

I was born in Heraklion, Crete. This is the place i grew up, studied and currently live. I mostly spent my childhood in Herkalio and the places my parents grew up. My father's birth place is a village called Roussa Ekklisia (~10 km from Sitia). My mother's place is a mountain village called Anogeia (located at the slopes of Psiloreitis mountain).

I graduated from High School in 2001 and joined the Department of Applied Mathematics of University of Crete. In 2004 I joined Computer Science Department where I received my Bachelor degree in 2008 and my Master of Science on Information Systems in 2010. From 2007 I have been a member of Information Systems Laboratory (FORTH-ICS) with an one-year interval that found me in the army (in 2010).

Nowadays I live in Iraklion and work as an R & D Engineer at the Information Systems Laboratory of Institute of Computer Science, FORTH. My main research interests include: information systems, conceptual modelling, knowledge representation using Semantic Web technologies, semantic data integration, object-oriented languages and frameworks. I have been involved in several national, European and international projects. I have co-authored more than 45 publications in several conferences, scientific journals and periodicals, and have received one best paper award (MTSR'2020) Finaly, I have co-authored book Cinderella’s Stick: A Fairytale for Digital Preservation with my colleauge Yannis Tzitzikas.

In my free time I enjoy moving around with my family (Katerina, Marianna and Giorgos) and friends. My hobbies include: reading, hiking, travelling with my bike.

You can find my detailed CV here, as well as a short version here
