Hi! I am currently responsible for the Secure Software Engineering Group at the DLR Institute of Data Science in Jena. We provide software developers with the tools, methods and processes that they need to develop secure software.

Previously, I completed my PhD with the Computer Vision Group at Friedrich-Schiller-Universität Jena on the integration of semantic knowledge and machine learning. Semantic knowledge can help fill the gap and interpret new types of data, for example imprecise labels.

If you are interested, check out my CV and publications.
