CV

2021-today University of Duisburg-Essen
Junior Professor

Currently, I am a Junior Professor at the Department of Computer Science and Applied Cognitive Science at the University of Duisburg-Essen in Germany. Here, I lead the research group colaps and our research explores the use of computational methods for modeling and analysis of learning processes both in formal and informal learning contexts.

2018-2021 University of Tartu
Senior Researcher

In Tartu, I worked on using learning analytics to provide feedback and guidance to students and to scaffold learning.  In particular, we focused on using student data derived from the Study Information System of the university to provide valuable information about students’ progress through teacher and student dashboards. 

2016-2018 Carnegie Mellon University
Postdoctoral Fellow

In Pittsburgh USA, I worked as a postdoctoral research fellow at the Human-Computer Interaction Institute at Carnegie Mellon University. There I collaborated with Bruce McLaren and Sandra Katz, Patricia Albacete and Pamela Jordan (LRDC, University of Pittsburgh) on a project that aimed to support students who learn physics with the use of adaptive tutorial dialogues. I designed a student model that evaluates the student’s understanding of the physics curriculum and adapts tutorial dialogues accordingly, with respect to content, style and language.

2014 - 2016 University of Duisburg-Essen
Postdoctoral Researcher

During my time in Duisburg as a postdoc, I worked with Prof. Ulrich H. Hoppe as a member of the COLLIDE research group. There, I focused on using learning analytics to analyze learning activities in various educational settings such as computer-supported collaborative learning environments, online labs, and MOOCs.

2009-2014 University of Patras
Ph.D. in Educational Technologies and HCI

During my PhD research with Nikolaos Avouris at the University of Patras (Greece), I focused on human-computer interaction (HCI), machine learning and computer-supported collaborative learning (CSCL). The subject of my thesis was the use of learning analytics for the assessment of collaboration quality in CSCL activities; thereby I proposed and implemented an “automatic rater” of collaboration quality using time series analysis.

2001-2005 University of Patras
Diploma in Electrical and Computer Engineering

I studied Electrical and Computer Engineering at the University of Patras with an emphasis on Electronics, Processors and Computer Architecture. My diploma thesis - under the supervision of Prof. Stavros Koubias - proposed an information system for the monitoring and management of geographically distributed networks. 

1996-2001 ATEI Piraeus
Diploma Computer Systems Engineering

I received my first higher academic degree on Computer Systems Engineering at the Piraeus University of Applied Sciences (ATEI Piraeus). There, I worked with Prof. Sotiris Leventis on Computer Networks as a member of PeLAB. 

Professional Materials

Teaching statement

I am dedicated to bridging the gap between theory and practice and to engage learners in modern, technology-enhanced learning activities for preparing the 21st century citizens for their future endeavors.

Research statement

I engage in exploring data traces and seeking patterns that provide insights about learning and are backed up by theoretical reasoning. My contributions are in student modeling and learning
analytics.
