Dynamics of Scientific Collaboration Networks Due to Academic Migrations

Academic migration is the change of host institution by aresearcher, typically aimed at achieving a stronger research profile. Scientificfeatures such as the number of collaborations, the productivityand its research impact tend to be directly affected by such movements.In this paper we analyse the dynamics of the collaboration network ofresearchers as they move from an institution to the next one. We specificallyhighlight cases where they increase and when they shrink, andquantify the dependency between the collaboration networks before andafter such a movement. Finally, we drill down the analysis by dividingmovements depending on the career stage of the researchers. Theanalysis shows a remarkable dynamism of collaboration network acrossmigrations. Interestingly, not always movements result in larger collaborationnetworks, while the overall similarity between networks acrossmovements is quite limited on average. Qualitatively, the same effectscan be found at all career stages, while clearly the magnitude of themmight vary. These results are based on a dataset extracted from Scopus,containing detailed scientific information for the publications of 84,141researchers.
