Matthias Ehlenz

Dr. Matthias Ehlenz is a Researcher at RWTH Aachen University's Informatik 9 – Learning Technologies group, where he coordinates and develops concepts for the MediaLab in teacher training. He holds a Dr. rer. nat. (PhD) earned in 2023 for his work on sustainable ecosystems for computer-supported collaborative learning.

His research focuses on:

• Learning analytics infrastructures (xAPI, multimodal data)
• Collaborative learning technologies (multi-touch tables, VR/XR environments)
• Serious game design and assessment
• Human-centered approaches in educational technology
• Open science and sustainable EdTech development

Ehlenz's recent publications (2021-2025) demonstrate strong interdisciplinary trends: 40% focus on learning analytics infrastructures, 30% examine collaborative interfaces (tabletops/XR), 20% address teacher training/digital pedagogy, and 10% explore open science practices. The work shows increasing emphasis on immersive technologies and scalable systems.

He actively advises graduate researchers, supervising at least six master's/bachelor's candidates on topics including:

• XR learning environments
• AI in education
• Learning analytics interfaces
• Collaborative game design

Ehlenz co-leads the Learning Technologies Innovation Lab, developing open-source tools for educational research. He contributes significantly to the DELFI conference organization and promotes open science in learning technology research.
