Prof. Dr. rer. nat. habil. Timo Ropinski

Prof. Ropinski heads the Visual Computing Group at Ulm University. Before moving to Ulm, he was Professor in Interactive Visualization at Linköping University in Sweden where he was heading the Scientific Visualization Group. Prof. Ropinski has received his Ph.D. in computer science in 2004 from the University of Münster, where he has also completed his habilitation in 2009.

Research Interests

The focus of the Visual Computing Group is on interactive visualization and visual analytics, whereby new insights are derived from existing data. Therefore, we develop and evaluate visual data analysis methods to make big and complex data comprehensible. Our results are new algorithms and interactive software. We apply our work in medicine and the natural sciences (astronomy, biology and physics) as well as in areas such as cultural heritage and disaster management. Besides desktop systems, our solutions are designed for mobile devices, head-mounted displays and our Powerwall setup.

Teaching

 

We also continuously offer interesting topics for bachelor and master theses. Information about the procedure and examples for current topics can be found at our thesis topics site.
