Our research focuses on methods, tools, and theories for the construction of manageable, reliable, adaptable, and evolvable software systems, ranging from embedded systems to large-scale systems. In our research projects, we concentrate on software product lines, but aim at applying our results also to other fields.

In particular, we are interested in:

• Programming methods (feature orientation, generative techniques, modularity)
• Software engineering (variability, feature interactions, domain-specific optimization)
• Empirical methods (program comprehension, the human factor, neuro imaging)
• Formal methods (program algebra, type systems, program analysis)

In our work, we combine formal and empirical methods. Furthermore, we develop tools to demonstrate the practicality of our research results.
