A key vision driving my research is to empower software engineering practice to enter an era of intensive automation. I develop and evaluate methods, tools, and theories for the construction and analysis of efficient, reliable, maintainable, and configurable software systems. In this endeavor, I pay special attention to the human factor and interdisciplinary research questions. In particular, I am interested in:
| Software variability and configuration |
| AI-based program generation and optimization |
| Socio-technical software analysis |
| Empirical and neurophysiological methods |
I apply my research results routinely to real-world software systems and projects from various domains, both from the open-source realm or in collaborations with partners from industry, such as Siemens AG, Bosch Engineering, and Airbus Helicopters.
