I am a post-doctoral visualization researcher in Hanspeter Pfister's group at the Harvard School of Engineering and Applied Sciences. I did both my PhD and Master's at at the Institute for Computer Graphics and Vision at the Graz University of Technology under the supervision of Prof. Schmalstieg. In 2011 I was a visiting researcher at Prof. Peter Park's Computational Genomics Research Group at Harvard Medical School.

My primary research interests are data visualization, mainly applied to molecular biology, and human computer interaction. My focus is my work on Caleydo, which is both, software that can be used by life science experts to visualize biomolecular data and pathways, but also a platform for implementing prototypes of more radical visualization ideas.

I am particularly interested in subset visualization for heterogeneous datasets in a molecular biology context. A recent application example of this research is StratomeX, a Caleydo view for cancer subtype analysis. For more information visit or look at the video.

My second major research topic is visualization related to biological networks (pathways). An example is the enRoute technique which enables users to explore large quantities of experimental data in the context of pathways. Check out or look at the video.
