I work on the design and implementation of visual analytics approaches for complex data from application areas, in particular from the life sciences, and on network analysis and graph drawing algorithms as well as their underlying graph theoretical principles. A further focus of my research is on Immersive Analytics, a research direction that studies how technologies can facilitate a deep cognitive, perceptual and/or emotional involvement of humans when understanding and reasoning with data.
I am involved in a variety of research collaborations with researchers from the life sciences, and participate in a number of software projects that realize the developed concepts in free open source software for use in the corresponding communities, see below. Due to the nature of my research, my interests overlap with a variety of research fields, including visual/immersive analytics, information visualization, HCI, network visualization, graph drawing, and algorithm engineering.
