Hi! Thanks for visiting my page. I am a group lead at the DLR Institute of Data Science in Jena, responsible for our Secure Software Engineering Group. We apply and advance machine learning methods to provide software developers with tools, methods and processes that support them in developing 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.
