My research at Kassel University includes knowledge discovery in bipartite graph structures, in particular their relation to formal concept analysis, and the application Algebra, Geometric Measure Theory, Topology and Logic, at the intersection of Knowledge Discovery, Machine Learning, and Reasoning.
I am also a senior developer of the blue social bookmark and publication sharing system BibSonomy as well as maintainer of the Formal Concept Analysis Tool conexp-clj.
In Summer 2019 I was on leave for an interim professorship at Humboldt University of Berlin.

Accompanying my theoretical research, these are the projects I am mainly work, i.e., develop program code for.
conexp-clj — a research tool for FCA
The research unit Knowledge & Data Engineering continues the development of the research tool conexp-clj, originally created by Dr. Daniel Borchmann. The continuous enhancement of the software package is supervised by Tom Hanika. Having such a tool at hand, the research group is able to test and analyze the theoretical research efforts in the realm of formal concept analysis and related fields.

BibSonomy is a scholarly social bookmarking system where researchers manage their collections of publications and web pages. BibSonomy is an open source project, continously developed by researchers in Kassel, Würzburg, and Hanover. Functioning as a test bed for recommendation and ranking algorithms, as well as through the publicly available datasets, containing traces of user behavior on the Web, BibSonomy has been the subject of various scientific studies.

The WISKIDZ project was a joint project of the International Centre for Higher Education Research (INCHER-Kassel) and the Interdisciplinary Research Center for Information System Design (ITeG) at the University of Kassel, supported by the BMBF. It contributed to a better understanding of long-term developments in the recruiting behavior in public research and individual career paths after obtaining a doctoral degree. The analyses are based on dissertation data, which are supplemented by information on publications, patents and macro-economic data among others. Essentially the project aims to understand changes in recruiting behavior over time with a special focus put on disciplinary idiosyncrasies. We create and analyze genealogies of doctoral students and their advisors in selected fields (physics, electronics, management and medieval history) from 1945 to the present. Further the project probes into the interdependencies of academic and non-academic employment opportunities of young researchers.
