Currently I'm working in the DFG project Hybris (Hybrid Reasoning for Intelligent Systems) on probabilistic Description Logics based on the aggregating semantics and the principle of maximum entropy. Previously, I have been a doctoral student in the QuantLA Research Training Group, where my research was focused on the use of similarity measures in Description Logics.
