The Carl von Ossietzky University welcomes numerous international researchers every year and is pleased about the lively exchange in teaching and research. In the overviews below you will find statistical data and geographical overviews of the researchers present in the respective calendar year. Please note that the figures only take into account those international researchers who have registered with the International Office on a voluntary basis for the duration of their stay (sometimes short-term, but also longer-term, e.g. as part of an employment contract) or who are known to the International Office through supervised funding programmes.
