I’m Kristian Sandahl, professor in Software Engineering at Linköping University in Sweden. My passion is to do research and teach about methods and tools for developing, operating, and maintaining large-scale software system with the right quality to the right cost. Most of my research is done in cooperation with industry and most of my teaching is done in connection to project work. I find empirical methods and experiments especially useful in understanding the complex endeavor of taking advantage of software technology.
