Dr. H. Ulrich Hoppe holds a full professorship in the area of “Collaborative and Learning Support Systems” at the University of Duisburg-Essen (Germany). After his PhD on interactive programming in mathematics education in 1984, Ulrich Hoppe has worked for about ten years in the area of intelligent user interfaces and cognitive models in HCI, before he re-focused his research on intelligent support in educational systems and distributed collaborative environments in 1995. With his COLLIDE Research Group he has participated in more than ten European projects on Technology-enhanced learning.

Since 2015 he is engaged as a PI in a Research Training Group on “User Centred Social Media” funded by the German National Science Foundation (DFG). His current research is focused on computational techniques for learning and knowledge building in various context, including higher education as well as vocational education and training. He is an active member of the Learning Analytics community where he particularly pursues the integration and adaptation of computational methods, such as combinations of (social) network analysis with other methods of data mining and artefact analysis.
