Experts and project leaders are crucial for the success of the summer school and its projects. They are knowledgeable either in computational social science methods or migration research (or both) and have some experience in supervising motivated junior scientists. Experts and projects leaders propose an own research project for the summer school for which interested junior scientists can apply. During the summer school, they work together with one other expert and up to four students on their proposed topic. We, therefore, welcome experts/project leader-team applications. They supervise their project team and ideally finish the project with a publication. Approximately 50 percent of the summer school will be devoted to project work which can be freely structured by the experts and project leaders. In addition, we expect them to give one plenary lecture or hands-on workshop for all summer school participants in order to give all participants a broader overview of the field.
