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