2023 - today
University of Duisburg Essen
Professor (W2 / tenured)
I am a Professor of Computational Methods in Modeling and Analysis of Learning Processes 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 such as Artificial Intelligence, Learning Analytics and Data Mining to model how we learn both in formal and informal learning contexts.
2021-2023
University of Duisburg-Essen
Junior Professor
In April 2021, I moved to the University of Duisburg-Essen, Germany as a Junior Professor at the Department of Computer Science and Applied Cognitive Science. My work focused on computational methods for modeling and analysis of learning processes in multiple contexts including, intelligent learning environments, online learning and project-based learning.
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.
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.
