M.Sc. Paul Maximilian Bittner

I apply programming language methods to software engineering research problems. In particular, I focus on static variability in software and systems and understanding changes to it (e.g., in version control). In my research, I apply formal reasoning to ensure that the models we use are correct, expressive, and useful. Devoted to denotational design, I thereby strive to find proper formal specifications of systems, which might be implemented in several, potentially optimized ways. Within the research project VariantSync, Alexander Schultheiß and me are striving towards making software product-line technology easier to adopt, in particular in clone-and-own development. A notable software project we developed is DiffDetective, a Java library for variability-aware differencing.

Anything of your interest? Don't hesitate to contact me. :)
