My work centers around the concept of Interactive Visual Analysis - short Visual Analytics (VA). The overarching goal of VA is to integrate the power of automatic data analysis and interactive methods to enable knowledge generation. Visualization, thereby, plays a key role in presenting information; it is capable of making patterns salient, which may not be identified by looking at statistics only. In the era of Big Data, we process and present vast amounts of heterogeneous data in constant pursuit of insight. A main challenge in understanding such complex data is to identify, interpret, and navigate relevant discernible areas (patterns) such as clusters, outliers, or correlations. Over the past years, I addressed this challenge and developed novel methods to make sense of large sets of heterogeneous data. Following, you may get an impression of my work. I collected some projects as well as relevant publications.
