I am a Professor and head of the Institute of Computer Graphics and Knowledge Visualization at the Faculty for Computer Science and Biomedical Engineering of Graz University of Technology. My main research interests are in Visual Data Analysis and in applied 3D Object Retrieval. The research questions we are tackling in my group include, among others, how large collections of data, e.g., high-dimensional and spatial-temporal data, and 3D object data, can be visually explored and analysed for data understanding and decision making. We are researching how users can interactively search for visual patterns in data, assisted by similarity functions, visual quality measures, and novel search interfaces, including approaches based on user sketching and eye tracking. We are interested in how to interactively visualize and steer machine-learning approaches like clustering and regression analysis by users, supporting effective and scalable data exploration. Our considered application areas include data exploration for engineering and industrial applications, in research data repositories, digital libraries and 3D cultural heritage object collections. We have worked in national research projects sponsored by the Austrian Science Fund FWF, the Austrian Research Promotion Agency FFG, the German Research Foundation DFG, Fraunhofer Gesellschaft, and EU projects.
