Profile
I am currently a PhD Student in the Computer Engineering and Informatics Department (CEID) of the University of Patras, where I received my MSc Diploma in 2011. The title of my postgraduate thesis was “Automatic Generation of Expert Systems with Certainty Factors from Datasets”. Since 2009, I am a member of the Laboratory of Graphics, Multimedia & GIS of the Department, with research interests in Artificial Intelligence and more specifically: Knowledge Representation and Reasoning, Semantic Web, and Training in Virtual Worlds. I have participated in several national and European research projects and have teaching experience in Vocational and Higher Education.
