Der Schwerpunkt meiner Forschung und meines Interesses liegt in den Bereichen Lernen durch Websuchen (engl. search as learning) und videobasiertes Lernen. Der Kernaspekt meiner Arbeit besteht in der Definition, Analyse und Vorhersage von Komplexität in multimodalen Lernressourcen wie Webseiten oder Videos.
