Short CV

My name is Alexandros Vassiliades, I was born in Thessaloniki Greece on the 1st of August 1992, but I have two nationalities Greek and Romanian.  I have finished the School of Mathematics in the Aristotle University of Thessaloniki during 2013-2017, with a grade among the top 10% of my class. Next, I attended the Master’s program of the same School with Title: “Theoretical Computer Science and Control Theory” during 201-2019 and got a grade of 8.99/10. On parallel, I was working as a private tutor for High-School and Bachelor students and had a 3 months internship at BETA CAE. Currently, I am pursuing my PhD with Professor Nick Bassiliades, and I am working on Knowledge Representation and Knowledge Extraction from the Semantic Web for Robotic Platforms, as well as on Argumentation.
