## about me

My research at Kassel University includes Applied Algebra, Logic, Applied Geometric Analysis and Applied Topology, at the intersection of Knowledge Bases, Machine Learning, and Reasoning.
Of particular interest to me are bipartite graph structures, their relation to formal concept analysis, and the application to social networks.
Further interests include permutation patterns and their connection to series parallel partial orders as well as machine learning in general.

I am also a senior developer of the blue social bookmark and publication sharing system BibSonomy.

## projects

Accompanying my research, these are the projects I participate to.-
#### Wiskidz

The WISKIDZ project is is 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 contributes 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. -
#### BibSonomy

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.
