I am a data engineer at Atypon and an affiliated researcher at Univeristy of Ioannina, Greece. Before that, I was a post-doctoral researcher at ATHENA Research Center, and at Athens University of Economics & Business, as well as a visiting lecturer at University of West Attica, Greece.

I received my PhD in Computer Science in 2016 from the National Technical University of Athens, under the supervision of Prof. Timos Sellis  [thesis: "Personalized, Semantic and Exploratory Data Analysis"]. In 2009 I received my Diploma on Electronic & Computer Engineering from the Technical University of Crete, supervised by Prof. Stavros Christodoulakis.
