The language that is used in research groups in Germany depends on the subject area involved and the institute concerned. Research groups in Germany are increasingly working in international teams. Thus, advanced English skills are usually taken for granted. At German institutes, especially in the natural and engineering sciences, researchers often research as well as publish their findings in English.
In many humanities and social science subjects, adequate knowledge of German is a requirement for a successful research stay. Depending on the research project, you may need to furnish proof of your language skills with your fellowship application.
