Research topics: Information Visualization (InfoVis) • Visual Analytics • Human-Computer Interaction (HCI) • User-Centered Design

Wolfgang is an expert in Information Visualization (InfoVis) and Visual Analytics (VA), particularly in the context of time-oriented data. He performs research on concepts, methods, and software prototypes that support humans in dealing with large and complex information structures, to make them more comprehensible, facilitate exploration, and enable knowledge discovery. Wolfgang has authored and co-authored more than 125 peer-reviewed articles and is an author of the book “Visualization of Time-Oriented Data” (Springer, 2011) that is devoted to a systematic view of this topic.
