My PhD thesis is entitled "Methods for Enhanced Exploratory Clustering Analyses".

Clustering is pivotal for fundamental exploratory tasks. Several domains, such as computer vision, image segmentation, information retrieval as well as business purposes rely on clustering techniques. However, especially novice analysts require profond support in order to achieve valuable clustering results.

In my thesis, I present novel approaches to support (novice) analysts in order to achieve promising clustering results in a short time period. Instead of "throwing more machines at the problem" and thus reducing the runtime, my goal is to engineer thorough solutions, which can work on existing hardware.

My other research interests are in the area of Meta-Learning, Big Data, Exploratory Data Analysis and Deep Learning.
