I am a postdoctoral researcher at TH Köln - University of Applied Sciences. My main research interests are reproducible science and the evaluation of information access systems. On the one hand, I work on solutions to quantify reproducibility by analyzing the quality of reimplementations. On the other hand, reproducibility can be proactively ensured, and I am an advocate of logging metadata and making the data provenance of computational experiments transparent. Furthermore, I believe that user simulations are the solution to bridge the gap between system- and user-oriented evaluations and to better understand the generalizability of experimental outcomes. During my doctorate, I developed a living lab infrastructure to conduct interactive information retrieval experiments with technically reproducible information access systems.
