Talk of Prof. Helwig Hauser at FI MULet us invite you to the talk of our special guest Prof. Helwig Hauser from the University of Bergen, which will be held on the 8th of November (Thursday) at 3 PM in the D2 room. From One to Many in Visualization A lot of interesting development has been happening in visualization research in the past 25 years. Certain topics, like medical visualization, flow visualization, tabular data visualization, and network visualization have attracted continued interest over many years and every year fascinating new findings are presented. We focus on the important work of optimizing our solutions and maturing the field. Every now and then, however, we also see promising chances for radical innovation, for new pioneering research in visualization. In this talk, we take a look at one of these chances, i.e., to transition from the visualization of individual datasets to visually studying large sets of datasets, for example from medical cohort studies or from numerical ensemble simulations. It seems that relevant new visualization challenges arise, when hundreds or thousands of datasets are studied simultaneously—in particular, when these are sets of multi-aspect spatiotemporal datasets. This talk brings up some of the related major questions (for example: how to map to the 2D/3D visualization space), together with examples of related work, and hopefully inspires some bright minds to conduct more visualization research on this topic of increasing relevance. Helwig Hauser's Short Bio Helwig Hauser graduated in 1995 from Vienna University of Technology in Austria and in 1998 he finished his PhD project on the visualization of complex dynamical systems (flow visualization). In 2003, he got his Habilitation at TU Wien, entitled ''Generalizing Focus+Context Visualization''—in 2006 this work was awarded with the Heinz-Zemanek Award by OCG. Already in 2004, his work on the interactive visual analysis of simulation data won the IEEE Visualization Contest in Austin. In 2013, Helwig Hauser then received the Dirk Bartz Prize for Visual Computing in Medicine from Eurographics (medical ultrasound data visualization). With >190 refereed publications and >7500 citations (h-index ≈ 50), he is an active and respected member of the international visualization research community. Recently, he chaired/hosted several important visualization conferences, including EuroVis 2011, PacificVis 2012, IEEE InfoVis 2013 & 2014, and VCBM 2016 in Bergen, and he has been serving as associate editor for three of the central journals (including IEEE TVCG, CGF, and C&G). After first working for TU Wien as assistant and later as assistant professor (1994–), he changed to the new VRVis Research Center in 2000 (having been one of the founding team, also). There, he led the basic research group on interactive visualization (until 2003) before he became the scientific director of VRVis (–2007). Since then, he is professor in visualization at the University of Bergen in Norway, where he built up a new research group on visualization.
