She has received a Diploma and Ph.D. degree from the Department of Electrical and Computer Engineering from the National Technical University of Athens (NTUA). Her research interests lie in the fields of artificial intelligence, human-computer interaction and software engineering. She has participated as a main researcher/coordinator in more than 30 related national and European-funded projects. Dr. Sgouropoulou has published more than 150 articles in internationaljournals, scientific collections and conference proceedings. She is an acting reviewer in distinguished journals and has served as General Chair, Program Chair and Steering Committee member in major international computer science conferences and participated in several Program and Organizing conference committees. Dr. Sgouropoulou has been prominently active in the area of European Learning Technologies Standardization. She has been a member of the European Standardization Committee (CEN) Workshop on Learning Technologies since 2000, and since 2007 she has been the Head of the Greek delegation of the Hellenic Organization for Standardization (ELOT) to the CEN Technical Committee 353 “ICT for Learning, Education and Training” and the coordinator of its Greek Mirror Committee TC48/WG3. As a field expert, Dr. Sgouropoulou has been appointed by CEN to contribute/coordinate several of its standardization projects on leaning objects, learning opportunities, learner mobility and learning outcomes/competence information. The results of this research work have been published as technical specifications (CEN Workshop Agreements) of the European Standardization Committee and have been presented to the scientific community as published articles. In 2010, Dr. Sgouropoulou was elected Vice-Chair of CEN TC353. Dr. Sgouropoulou has coordinated standardization activities on a “European Learner Mobility Model” for the development of a European Norm on European Learner Mobility Achievement Information (EuroLMAI). In February 2011, the EuroLMAI was formally voted by Member States and is now one of the first European Norms in the field of Learning Technologies.
