About Myself

I studied informatics at the Friedrich Schiller University Jena (Jena is a beautiful little town in Thuringia - the green heart of Germany - that is definitely worth a visit). During my studies, I focused on computer vision and software engineering. 

Since March 2019, I am a PhD student with Timo Kehrer at Humbold University of Berlin and part of the VariantSync project. My main research interests lie in the systematic support of multi-variant software development, version control, and improving the way in which we as a community conduct our scientific work.
