I am currently a researcher in the Visual Information Analysis Group of Prof. Dr. Heike Leitte, where I recently finished my PhD thesis. My thesis deals with investigating how to exploit topological information for the visualization of complex multivariate data sets. See below for a list of my publications and other materials.

I also have a profile on ResearchGate.

Research interests

In general, I am interested in methods and techniques that help us understand complex data sets. Mostly, those data sets are high-dimensional point clouds for me, but I am also interested in analysing graphs or, most recently, networks. I am also interested in analysing the behaviour of machine learning techniques, such as dimensionality reduction algorithms or clustering techniques.

According to Rob Hyndman, this makes me a data scientist!

From the mathematical side, I am interested in investigating how to use methods from algebraic topology to support the analysis of multivariate data. Since multivariate, unstructured point clouds are very common in domains such as biology and climate research, there are many potential applications for this kind of research. During my PhD, I mainly used persistent homology as a tool for describing a data set. I also have a general interest in algebraic & differential topology—both fields contain a wealth of potentially useful tools for visualization!

Some of my colleagues also have personal websites (or used to have them; they are still my colleagues, but their websites unfortunately do not exist any more for one reason or another):
