The core research interest of ICET-lab is in software engineering for distributed, Web, and cloud-based systems. The overarching goal of the team is to understand how developers use emerging Internet technology, and to support the community in using these technologies effectively. Many of our studies have an empirical slant (e.g., we crawl open source repositories, send out surveys, or conduct interviews), but we also frequently conduct experimental research (e.g., controlled lab experiments, field studies, or performance evaluations). We are also keen on building proof-of-concepts and tools. We are commited to open and reproducible science, as well as to transferring our results to industry and society as a whole. As part of this, we often speak about our work at academic and industrial conferences.
Virtually all our papers are available freely via the green open access model. If you cannot find a specific paper you are always free to email the authors, we will happily provide a (text-identical) preprint version.
ICET-lab currently receives major financial support from the Wallenberg AI, Autonomous Systems, and Software Programme (WASP), the ICT Area of Advance at Chalmers, the Swedish Research Council (VR), and the Swiss National Science Foundation (SNF).
