I wear the hats of Data Scientist and Software Engineer since 2017.
I’m part of the Transregional Collaborative Research Centre “TRR-248: Foundations of Perspicuous Software Systems”, funded by the DFG, where I indulge on my research interests by developing interactive visualization approaches for exploration and explanation of computational models and analysis of cyber-physical systems.
