I hold a Computer Engineering degree and a Master’s degree in Artificial Intelligence. As a Ph.D. in Semantic Web, I specialized in meta-modeling, ontologies, and graph data representations. I worked at Orange Labs (Meylan, France) in IoT graph data representations and became a member of ETSI Standardization Community in Europe. I taught in several universities in France and Lebanon.
