Speakers & Experts

Three keynote speeches from leading scholars in the field will introduce computational social science and the topic of social cohesion. Our experts are experienced scholars either in computational social science methods or on the research topic of important aspects of social cohesion (or both). During the summer school, each experts gives a lecture and/or a hands-on workshop.

Most of our experts will also lead projects. During the summer school, two experts work together and build a team with up to four students on one specific research topic. The experts’ task is to lead the research project and supervise students. Ideally, the research project finishes with a publication.
