Theses

I am glad to supervise theses in the field of Information Visualisation. Hereby we mainly rely on the Javascript Framework D3 for fast and easy development of visualizations. Here I would like to present some general research topics of my interest as well as concrete topics. If you are interested in a thesis or if you do have something you would like to work on which fits my field, feel free to write me an email or drop by my office.

Theses on the perception of visualization (Bachelor- & Masterthesis)

Theses in this area aim to understand how observers perceive visualization. Using these insides, we then try to find to visualizations can be improved in order to make them more accessible and therefore easier to find answers to given questions or while exploring the data.

Theses on Informationvisualization (Bachelor- & Masterthesis)

Theses in this area aim to visualize various data like for example email-traffic, dynamic graphs, computer networks, social media, or even satellite orbits. These visualizations should then help observers to find answers to given questions or support them while exploring the data.
