Download CV


I received my M.Eng. in Electrical and Computer Engineering from the Aristotle University of Thessaloniki in 2012.

I work as a research associate and a software engineer since 2014. With participation in a long series of EU-funded research projects, I have acquired an elaborate expertise in the design and implementation of complex system architectures in the domains of e-health, digital preservation, security and crisis management. In parallel, I have worked on the implementation of sentiment extraction techniques from text with the use of knowledge graphs and NLP.

As a result, I have developed a critical skill set in the application of semantic technologies, knowledge graphs, linked data, semantic reasoning and natural language processing. Last but not least, I have several publications in international conferences and scientific journals.
